|
||||
|
||||
|
||||
## 1. Defines the *Prop*
|
||||
Defining a Bridge (Yun), Ethernet or Wifi *Prop* is slighlty different.
|
||||
|
||||
### Defining a *BridgeProp*
|
||||
```csharp
|
||||
#include <Bridge.h>
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
// If you're running our Escape Room control software (Room 2.0) you have to respect
|
||||
// prpos inbox/outbox syntax Room/[escape room name]/Props/[propsname]/inbox|outbox
|
||||
// https://live-escape.net/go/room
|
||||
|
||||
BridgeProp prop(u8"Arduino Contrôleur", // as MQTT client id, should be unique per client for given broker
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/inbox",
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/outbox",
|
||||
"192.168.1.42", // your MQTT server IP address
|
||||
1883); // your MQTT server port;
|
||||
|
||||
PropDataLogical clignoter(u8"clignote", u8"oui", u8"non", true);
|
||||
PropDataLogical led(u8"led");
|
||||
|
||||
void clignote(); // forward
|
||||
PropAction clignoteAction = PropAction(1000, clignote);
|
||||
```
|
||||
Create *BridgeProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
The *Bridge* instance is created by `#include <Bridge.h>`.
|
||||
|
||||
### Defining an *EthernetProp*
|
||||
```csharp
|
||||
#include <Ethernet.h>
|
||||
#include <IPAddress.h>
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
byte mac[] = { 0xFC, 0xFA, 0xEA, 0x00, 0x00, 0x02 }; //<<< MAKE SURE IT'S UNIQUE IN YOUR NETWORK!!!
|
||||
String ip = "192.168.1.19"; //<<< ENTER YOUR IP ADDRESS HERE ("" for DHCP)
|
||||
|
||||
// Builtin led is not available with the shield
|
||||
#undef LED_BUILTIN
|
||||
#define LED_BUILTIN 8
|
||||
|
||||
// If you're running our Escape Room control software (Room 2.0) you have to respect
|
||||
// prpos inbox/outbox syntax Room/[escape room name]/Props/[propsname]/inbox|outbox
|
||||
// https://live-escape.net/go/room
|
||||
|
||||
EthernetProp prop(u8"Arduino Contrôleur", // as MQTT client id, should be unique per client for given broker
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/inbox",
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/outbox",
|
||||
"192.168.1.42", // your MQTT server IP address
|
||||
1883); // your MQTT server port;
|
||||
|
||||
PropDataLogical clignoter(u8"clignote", u8"oui", u8"non", true);
|
||||
PropDataLogical led(u8"led");
|
||||
|
||||
void clignote(); // forward
|
||||
PropAction clignoteAction = PropAction(1000, clignote);
|
||||
```
|
||||
Create MAC address (which must be unique, it's the hardware ID in the netwprk).
|
||||
|
||||
Create *EthernetProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
The *Ethernet* instance is created by `#include <Ethernet.h>`.
|
||||
|
||||
### Defining a *WifiProp*
|
||||
```csharp
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
// Setup your WiFi network
|
||||
const char* ssid = "";
|
||||
const char *passphrase = "";
|
||||
|
||||
// Builtin led is not available with the shield
|
||||
#undef LED_BUILTIN
|
||||
#define LED_BUILTIN 8
|
||||
|
||||
// If you're running our Escape Room control software (Room 2.0) you have to respect
|
||||
// prpos inbox/outbox syntax Room/[escape room name]/Props/[propsname]/inbox|outbox
|
||||
// https://live-escape.net/go/room
|
||||
|
||||
WifiProp prop(u8"Arduino Contrôleur", // as MQTT client id, should be unique per client for given broker
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/inbox",
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/outbox",
|
||||
"192.168.1.42", // your MQTT server IP address
|
||||
1883); // your MQTT server port;
|
||||
|
||||
PropDataLogical clignoter(u8"clignote", u8"oui", u8"non", true);
|
||||
PropDataLogical led(u8"led");
|
||||
|
||||
void clignote(); // forward
|
||||
PropAction clignoteAction = PropAction(1000, clignote);
|
||||
```
|
||||
The *AduinoProps* library uses **<a href="https://github.com/arduino-libraries/WiFiNINA" target="_blank">WiFiNINA</a>** WiFi library for **Arduino Uno WiFi Rev 2**, **Arduino NANO 33 IoT**, **Arduino MKR WiFi 1010** and **Arduino MKR VIDOR 4000**.
|
||||
|
||||
Please update the WiFiNINA firmware: [WiFiNINA firmware update](WifiNinaFirmware.md).
|
||||
|
||||
Create *WifiProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
#### MQTT topics
|
||||
The prop listens to the *inbox* topic for command messages and send data and messages into the *outbox* topic.
|
||||
|
||||
If you're running Live Escape Room 2.0 control software, you have to respect *inbox*/*outbox* syntax:
|
||||
|
||||
Room 2.0 *inbox* topic:
|
||||
```csharp
|
||||
format: Room/[escape room name]/Props/[prop name]/inbox
|
||||
example: u8"Room/Demoniak/Props/Arduino Contrôleur/inbox"
|
||||
```
|
||||
Room 2.0 *outbox* topic:
|
||||
```csharp
|
||||
format: Room/[escape room name]/Props/[prop name]/outbox
|
||||
example: u8"Room/Demoniak/Props/Arduino Contrôleur/outbox"
|
||||
```
|
||||
See [README.md](../README.md): **4. Application protocol for escape room 2.0 prop**.
|
||||
|
||||
#### *PropData* instances
|
||||
*PropData* provides a facility to monitor data sent into MQTT outbox.
|
||||
|
||||
See [PropData.md](PropData.md) for *PropData* reference.
|
||||
|
||||
#### *PropAction* instances
|
||||
To maintain a non-blocking asynchronous behavior of your prop, use *PropAction* objects to trigger action periodically.
|
||||
|
||||
Reading I/O and simple computing (arithmetics) can be done at every sketch loop but long computing have to run periodically.
|
||||
|
||||
For example, to blink a led, don't block the skecth with a `delay(1000)` call to switch the output: instead, ***check if 1 second is elapsed to switch the output***.
|
||||
|
||||
See [PropAction.md](PropData.md) for *PropAction* reference.
|
||||
|
||||
|
||||
## 2. Setup the *Prop*
|
||||
`InboxMessage::run` is the callback executed when a message is received in the MQTT inbox.
|
||||
```csharp
|
||||
void setup()
|
||||
{
|
||||
// CODE TO BEGIN THE INTERNET CONNECTION
|
||||
... see below the different code for BridgeProp, EthenetProps and WifiProp
|
||||
|
||||
// SAME CODE FOR ALL PROPS
|
||||
prop.addData(&clignoter);
|
||||
prop.addData(&led);
|
||||
|
||||
prop.begin(InboxMessage::run);
|
||||
|
||||
pinMode(LED_BUILTIN, OUTPUT); // initialize digital pin LED_BUILTIN as an output
|
||||
|
||||
// At this point, the broker is not connected yet
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
*BridgeProp*, *EthenetProps* and *WifiProp* has the exactly same setup:
|
||||
|
||||
- add *PropData* references to the prop
|
||||
- call `prop.begin(InboxMessage::run)`
|
||||
|
||||
The setup code is slighlty different to start the network client (bridge, ethernet of wifi):
|
||||
```csharp
|
||||
void setup()
|
||||
{
|
||||
#if defined(BRIDGEPROP_H)
|
||||
Bridge.begin();
|
||||
updateBrokerAdressFromFile("/root/broker", &prop); // if you're running our Escape Room control software (Room 2.0)
|
||||
|
||||
#elif defined(ETHERNETPROP_H)
|
||||
// can do more static IP configuration
|
||||
//Ethernet.setSubnetMask(IPAddress());
|
||||
//Ethernet.setGatewayIP(IPAddress());
|
||||
//Ethernet.setDnsServerIP(IPAddress());
|
||||
|
||||
IPAddress ipa;
|
||||
if (!ipa.fromString(ip)) {
|
||||
// attempt a DHCP connection:
|
||||
if (!Ethernet.begin(mac)) {
|
||||
// if DHCP fails, start with a hard-coded address:
|
||||
Ethernet.begin(mac, IPAddress(10, 90, 90, 239));
|
||||
}
|
||||
}
|
||||
else {
|
||||
Ethernet.begin(mac, ipa);
|
||||
}
|
||||
delay(1500); // time for shield stuff
|
||||
|
||||
#elif defined(WIFIPROP_H)
|
||||
// can do more static IP configuration
|
||||
//WiFi.config(IPAddress(), IPAddress(), IPAddress());
|
||||
//WiFi.config(IPAddress(), IPAddress());
|
||||
//WiFi.config(IPAddress());
|
||||
|
||||
WiFi.begin(ssid, passphrase);
|
||||
|
||||
while (WiFi.status() != WL_CONNECTED) {
|
||||
delay(500);
|
||||
}
|
||||
#endif
|
||||
...
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
### Change timings
|
||||
Default timings are:
|
||||
* check data changes every 400 milliseconds
|
||||
* *Prop* remains silent for up to 30 seconds
|
||||
|
||||
Timings can be changed anywhere in the code with `resetIntervals()`:
|
||||
```csharp
|
||||
prop.resetIntervals(250, 15); // check data changes every 250 milliseconds, silent up to 15 seconds
|
||||
```
|
||||
|
||||
|
||||
## 3. Call in *loop()*
|
||||
```csharp
|
||||
void loop()
|
||||
{
|
||||
prop.loop();
|
||||
|
||||
led.setValue(digitalRead(LED_BUILTIN)); // read I/O
|
||||
|
||||
clignoteAction.check(); // do your stuff, don't freeze the loop with delay() calls
|
||||
}
|
||||
|
||||
```
|
||||
Couldn't be more simple!
|
||||
|
||||
Just call `prop.loop()` when entering the sketch `loop()`, it will maintain MQTT broker connection and run callback when receiving MQTT messages.
|
||||
|
||||
|
||||
## 4. Implement `InboxMessage::run()` callback
|
||||
`InboxMessage::run` is the callback executed when a message is received in the MQTT inbox, you have to implement it.
|
||||
|
||||
Example for Room 2.0 commands:
|
||||
```csharp
|
||||
void InboxMessage::run(String a) {
|
||||
|
||||
if (a == u8"app:startup")
|
||||
{
|
||||
prop.sendAllData();
|
||||
prop.sendDone(a);
|
||||
}
|
||||
else if (a == "clignoter:1")
|
||||
{
|
||||
clignoter.setValue(true);
|
||||
|
||||
prop.sendAllData(); // all data change, we don't have to be selctive then
|
||||
prop.sendDone(a); // acknowledge prop command action
|
||||
}
|
||||
else if (a == "clignoter:0")
|
||||
{
|
||||
clignoter.setValue(false);
|
||||
|
||||
prop.sendAllData(); // all data change, we don't have to be selctive then
|
||||
prop.sendDone(a); // acknowledge prop command action
|
||||
}
|
||||
else
|
||||
{
|
||||
// acknowledge omition of the prop command
|
||||
prop.sendOmit(a);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 5. Update broker address from SSH (*BridgeProp*)
|
||||
Room 2.0 use a SSH command to change remotely the broker IP address (in /root/broker file) and to relaunch to sketch:
|
||||
```bash
|
||||
ssh 'echo 192.168.1.14> /root/broker && reset-mcu'
|
||||
```
|
||||
On the *BridgeProp* you can read the broker IP address from Linino filesystem with this code:
|
||||
```csharp
|
||||
void updateBrokerAdressFromFile(const char* broker_file, BridgeProp* prop)
|
||||
{
|
||||
// broker IP address is stored in Linino file systems and updated with ssh command by Room 2.0
|
||||
IPAddress ip;
|
||||
|
||||
Process _process;
|
||||
_process.begin("cat");
|
||||
_process.addParameter(broker_file); // for ssh remotely set broker address
|
||||
_process.run(); // run the process and wait for its termination
|
||||
String b;
|
||||
while (_process.available() > 0) {
|
||||
char c = _process.read();
|
||||
b += c;
|
||||
}
|
||||
b.trim();
|
||||
|
||||
if (ip.fromString(b.c_str())) prop->setBrokerIpAddress(ip);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 6. Examples
|
||||
The library comes with a number of example sketches. See **File > Examples > ArduinoProps** within the Arduino IDE application.
|
||||
|
||||
See [EXAMPLES.md](../EXAMPLES.md) for an adaptation of the Blink example (https://www.arduino.cc/en/tutorial/blink) as a simple MQTT prop:
|
||||
|
||||
1. **BlinkOnBridgeProps**: the Blink example on a Yun prop with *ArduinoProps library*
|
||||
2. **BlinkOnEthernetProps**: the Blink example on an Ethernet prop with *ArduinoProps library*
|
||||
3. **BlinkOnWifiProps**: the Blink example on a Wifi prop with *ArduinoProps library*
|
||||
4. **BlinkOnBridgePubSub**: the Blink example on prop using *PubSubClient* directly
|
||||
|
||||
|
||||
## 7. Compatible hardware
|
||||
*Props library* supported harware:
|
||||
- Arduino Yún and Arduino Yún Rev 2
|
||||
- Any Arduino + Dragino Yún Shield (tested with Elegoo Mega 2560 R3)
|
||||
- Arduino Uno WiFi Rev 2
|
||||
- Arduino NANO 33 IoT
|
||||
- Arduino MKR WiFi 1010
|
||||
- Arduino MKR VIDOR 4000
|
||||
- Arduino Ethernet
|
||||
- Arduino Ethernet Shield
|
||||
|
||||
For WiFi prop, please update the WiFiNINA firmware: [WiFiNINA firmware update](WifiNinaFirmware.md).
|
||||
|
||||
To use other WiFi hardware compatible with any *<a href="https://github.com/knolleary/pubsubclient" target="_blank">Nick O'Leary PubSubClient</a>* library you have to fork `WifiProp.h` and `WifiProp.cpp` and to replace `WiFiNINA.h` whih appropriate WiFi library (`ESP8266WiFi.h` for example):
|
||||
- Arduino WiFi Shield
|
||||
- Sparkfun WiFly Shield – [library](https://github.com/dpslwk/WiFly)
|
||||
- TI CC3000 WiFi - [library](https://github.com/sparkfun/SFE_CC3000_Library)

# *Prop* class reference
|
||||
|
||||
*Prop* is a base class for 3 connected prop flavors, depending on their network interface:
|
||||
*Prop* is an interface (base class) implemented by 3 classes:
|
||||
* ***BridgeProp*** for Yun board and Yun shield
|
||||
* ***EthernetProp*** for Ethernet shield
|
||||
* ***WifiProp*** for WiFiNINA boards
|
||||
|
||||
*Prop* class reference:
|
||||
1. [Define the *Prop*](#1-defines-the-prop)
|
||||

|
||||
* Defining an *EthernetProp*
|
||||

|
||||
3. [Call in *loop()*](#3-call-in-loop)

|
||||
6. [Examples](#6-examples)
|
||||
7. [Compatible](#7-compatible-hardware) hardware
|
||||
## Constructors
|
||||
* `PropDataDecimal(const char *, uint8_t digits = 2, double precision = 0.1, double initial = 0)`
|
||||
* `PropDataInteger(const char *, double precision = 0.1, long initial = 0)`
|
||||
* `PropDataLogical(const char *, const char *trueval = NULL, const char *falseval = NULL, bool initial = false)`
|
||||
* `PropDataText(const char *)`
|
||||
|
||||
By default for *PropDataLogical*, `trueval` is `"1"` band `falseval` is `"0"`.
|
||||
|
||||
## 1. Defines the *Prop*
|
||||
Defining a Bridge (Yun), Ethernet or Wifi *Prop* is slighlty different.
|
||||
For *PropDataDecimal*, `digits` is the number of decimal digits in the display string.
|
||||
|
||||
### Defining a *BridgeProp*
|
||||
For *PropDataDecimal* and *PropDataInteger*, `precision` is the percentage threshold for deciding whether a change has occurred or not.
|
||||
|
||||
## Interface
|
||||
* `String fetch()`
|
||||
* `String fetchChange()`
|
||||
|
||||
*fetch()* always returns the `"var=value "` string ready to be sent in a `DATA` protocol message and update the `_previous` value.
|
||||
|
||||
*fetchChange()* checks whether a change has occurred or not. If a change occured, returns the `"var=value "` string ready to be sent in a `DATA` protocol message and update the `_previous` value. If no change occured, returns and empty string.
|
||||
|
||||
## Accessors and Mutators
|
||||
* `void setValue(const double|long|bool|String)`
|
||||
* `double|long|bool|String value() const`
|
||||
|
||||
Accessors and Mutators are typed according to *PropData* type.
|
||||
|
||||
## Usage
|
||||
|
||||
### Create a *PropData* instance
|
||||
```csharp
|
||||
#include <Bridge.h>
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
// If you're running our Escape Room control software (Room 2.0) you have to respect
|
||||
// prpos inbox/outbox syntax Room/[escape room name]/Props/[propsname]/inbox|outbox
|
||||
// https://live-escape.net/go/room
|
||||
|
||||
BridgeProp prop(u8"Arduino Contrôleur", // as MQTT client id, should be unique per client for given broker
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/inbox",
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/outbox",
|
||||
"192.168.1.42", // your MQTT server IP address
|
||||
1883); // your MQTT server port;
|
||||
|
||||
PropDataLogical clignoter(u8"clignote", u8"oui", u8"non", true);
|
||||
PropDataLogical led(u8"led");
|
||||
|
||||
void clignote(); // forward
|
||||
PropAction clignoteAction = PropAction(1000, clignote);
|
||||
```
|
||||
Create *BridgeProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
The *Bridge* instance is created by `#include <Bridge.h>`.
|
||||
|
||||
### Defining an *EthernetProp*
|
||||
```csharp
|
||||
#include <Ethernet.h>
|
||||
#include <IPAddress.h>
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
byte mac[] = { 0xFC, 0xFA, 0xEA, 0x00, 0x00, 0x02 }; //<<< MAKE SURE IT'S UNIQUE IN YOUR NETWORK!!!
|
||||
String ip = "192.168.1.19"; //<<< ENTER YOUR IP ADDRESS HERE ("" for DHCP)
|
||||
|
||||
// Builtin led is not available with the shield
|
||||
#undef LED_BUILTIN

Create MAC address (which must be unique, it's the hardware ID in the netwprk).
|
||||
|
||||
Create *EthernetProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
The *Ethernet* instance is created by `#include <Ethernet.h>`.
|
||||
|
||||
### Defining a *WifiProp*
|
||||
```csharp
|
||||
#include "ArduinoProps.h"
|
||||
|
||||
// Setup your WiFi network
|
||||
const char* ssid = "";
|
||||
const char *passphrase = "";
|
||||
|
||||
// Builtin led is not available with the shield
|
||||
#undef LED_BUILTIN
|
||||
#define LED_BUILTIN 8
|
||||
|
||||
// If you're running our Escape Room control software (Room 2.0) you have to respect
|
||||
// prpos inbox/outbox syntax Room/[escape room name]/Props/[propsname]/inbox|outbox
|

// https://live-escape.net/go/room
|
||||
|
||||
WifiProp prop(u8"Arduino Contrôleur", // as MQTT client id, should be unique per client for given broker
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/inbox",
|
||||
u8"Room/Demoniak/Props/Arduino Contrôleur/outbox",
|
||||
"192.168.1.42", // your MQTT server IP address
|
||||
1883); // your MQTT server port;
|
||||
|
||||
PropDataLogical clignoter(u8"clignote", u8"oui", u8"non", true);
|
||||
PropDataLogical led(u8"led");
|
||||
|
||||
void clignote(); // forward
|
||||
PropAction clignoteAction = PropAction(1000, clignote);
|
||||
```
|
||||
The *AduinoProps* library uses **<a href="https://github.com/arduino-libraries/WiFiNINA" target="_blank">WiFiNINA</a>** WiFi library for **Arduino Uno WiFi Rev 2**, **Arduino NANO 33 IoT**, **Arduino MKR WiFi 1010** and **Arduino MKR VIDOR 4000**.
|
||||
|
||||
Please update the WiFiNINA firmware: [WiFiNINA firmware update](WifiNinaFirmware.md).
|
||||
|
||||
Create *WifiProp* instance with MQTT parameters, then create *PropData* instances and *PropsActions*.
|
||||
|
||||
#### MQTT topics
|
||||
The prop listens to the *inbox* topic for command messages and send data and messages into the *outbox* topic.
|
||||
|
||||
If you're running Live Escape Room 2.0 control software, you have to respect *inbox*/*outbox* syntax:
|
||||
|
||||
Room 2.0 *inbox* topic:
|
||||
```csharp
|
||||
format: Room/[escape room name]/Props/[prop name]/inbox
|
||||
example: u8"Room/Demoniak/Props/Arduino Contrôleur/inbox"
|
||||
```
|
||||
Room 2.0 *outbox* topic:
|
||||
```csharp
|
||||
format: Room/[escape room name]/Props/[prop name]/outbox
|
||||
example: u8"Room/Demoniak/Props/Arduino Contrôleur/outbox"
|
||||
```
|
||||
See [README.md](../README.md): **4. Application protocol for escape room 2.0 prop**.
|
||||
|
||||
#### *PropData* instances
|
||||
*PropData* provides a facility to monitor data sent into MQTT outbox.
|
||||
|
||||
See [PropData.md](PropData.md) for *PropData* reference.
|
||||
|
||||
#### *PropAction* instances
|
||||
To maintain a non-blocking asynchronous behavior of your prop, use *PropAction* objects to trigger action periodically.
|
||||
|
||||
Reading I/O and simple computing (arithmetics) can be done at every sketch loop but long computing have to run periodically.
|
||||
|
||||
For example, to blink a led, don't block the skecth with a `delay(1000)` call to switch the output: instead, ***check if 1 second is elapsed to switch the output***.
|
||||
|
||||
See [PropAction.md](PropData.md) for *PropAction* reference.
|
||||
|
||||
|
||||
## 2. Setup the *Prop*
|
||||
`InboxMessage::run` is the callback executed when a message is received in the MQTT inbox.
|
||||
### Add the *PropData* instance to managed data of the *Props*
|
||||
```csharp
|
||||
void setup()
|
||||
{
|
||||
// CODE TO BEGIN THE INTERNET CONNECTION
|
||||
... see below the different code for BridgeProp, EthenetProps and WifiProp
|
||||
...
|
||||
|
||||
// SAME CODE FOR ALL PROPS
|
||||
prop.addData(&clignoter);
|
||||
prop.addData(&led);
|
||||
Props::addManagedLogicalData(&clignoter);
|
||||
|
||||
prop.begin(InboxMessage::run);
|
||||
|
||||
pinMode(LED_BUILTIN, OUTPUT); // initialize digital pin LED_BUILTIN as an output
|
||||
|
||||
// At this point, the broker is not connected yet
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
*BridgeProp*, *EthenetProps* and *WifiProp* has the exactly same setup:
|
||||
|
||||
- add *PropData* references to the prop
|
||||
- call `prop.begin(InboxMessage::run)`
|
||||
|
||||
The setup code is slighlty different to start the network client (bridge, ethernet of wifi):
|
||||
```csharp
|
||||
void setup()
|
||||
{
|
||||
#if defined(BRIDGEPROP_H)
|
||||
Bridge.begin();
|
||||
updateBrokerAdressFromFile("/root/broker", &prop); // if you're running our Escape Room control software (Room 2.0)
|
||||
|
||||
#elif defined(ETHERNETPROP_H)
|
||||
// can do more static IP configuration
|
||||
//Ethernet.setSubnetMask(IPAddress());
|
||||
//Ethernet.setGatewayIP(IPAddress());
|
||||
//Ethernet.setDnsServerIP(IPAddress());
|
||||
|
||||
IPAddress ipa;
|
||||
if (!ipa.fromString(ip)) {
|
||||
// attempt a DHCP connection:
|
||||
if (!Ethernet.begin(mac)) {
|
||||
// if DHCP fails, start with a hard-coded address:
|
||||
Ethernet.begin(mac, IPAddress(10, 90, 90, 239));
|
||||
}
|
||||
}
|
||||
else {
|
||||
Ethernet.begin(mac, ipa);
|
||||
}
|
||||
delay(1500); // time for shield stuff
|
||||
|
||||
#elif defined(WIFIPROP_H)
|
||||
// can do more static IP configuration
|
||||
//WiFi.config(IPAddress(), IPAddress(), IPAddress());
|
||||
//WiFi.config(IPAddress(), IPAddress());
|
||||
//WiFi.config(IPAddress());
|
||||
|
||||
WiFi.begin(ssid, passphrase);
|
||||
|
||||
while (WiFi.status() != WL_CONNECTED) {
|
||||
delay(500);
|
||||
}
|
||||
#endif
|
||||
...
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
### Change timings
|
||||
Default timings are:
|
||||
* check data changes every 400 milliseconds
|
||||
* *Prop* remains silent for up to 30 seconds
|
||||
|
||||
Timings can be changed anywhere in the code with `resetIntervals()`:
|
||||
### Use the *PropData* instance anywhere
|
||||
```csharp
|
||||
prop.resetIntervals(250, 15); // check data changes every 250 milliseconds, silent up to 15 seconds
|
||||
```
|
||||
clignoter.setValue(true);
|
||||
|
||||
...
|
||||
|
||||
## 3. Call in *loop()*
|
||||
```csharp
|
||||
void loop()
|
||||
{
|
||||
prop.loop();
|
||||
|
||||
led.setValue(digitalRead(LED_BUILTIN)); // read I/O
|
||||
|
||||
clignoteAction.check(); // do your stuff, don't freeze the loop with delay() calls
|
||||
}
|
||||
|
||||
```
|
||||
Couldn't be more simple!
|
||||
|
||||
Just call `prop.loop()` when entering the sketch `loop()`, it will maintain MQTT broker connection and run callback when receiving MQTT messages.
|
||||
|
||||
|
||||
## 4. Implement `InboxMessage::run()` callback
|
||||
`InboxMessage::run` is the callback executed when a message is received in the MQTT inbox, you have to implement it.
|
||||
|
||||
Example for Room 2.0 commands:
|
||||
```csharp
|
||||
void InboxMessage::run(String a) {
|
||||
|
||||
if (a == u8"app:startup")
|
||||
{
|
||||
prop.sendAllData();
|
||||
prop.sendDone(a);
|
||||
}
|
||||
else if (a == "clignoter:1")
|
||||
{
|
||||
clignoter.setValue(true);
|
||||
|
||||
prop.sendAllData(); // all data change, we don't have to be selctive then
|
||||
prop.sendDone(a); // acknowledge prop command action
|
||||
}
|
||||
else if (a == "clignoter:0")
|
||||
{
|
||||
clignoter.setValue(false);
|
||||
|
||||
prop.sendAllData(); // all data change, we don't have to be selctive then
|
||||
prop.sendDone(a); // acknowledge prop command action
|
||||
}
|
||||
else
|
||||
{
|
||||
// acknowledge omition of the prop command
|
||||
prop.sendOmit(a);
|
||||
}
|
||||
if (clignoter.value()) {
|
||||
digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
|
||||
led.setValue(digitalRead(LED_BUILTIN));
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 5. Update broker address from SSH (*BridgeProp*)
|
||||
Room 2.0 use a SSH command to change remotely the broker IP address (in /root/broker file) and to relaunch to sketch:
|
||||
```bash
|
||||
ssh 'echo 192.168.1.14> /root/broker && reset-mcu'
|
||||
```
|
||||
On the *BridgeProp* you can read the broker IP address from Linino filesystem with this code:
|
||||
```csharp
|
||||
void updateBrokerAdressFromFile(const char* broker_file, BridgeProp* prop)
|
||||
{
|
||||
// broker IP address is stored in Linino file systems and updated with ssh command by Room 2.0
|
||||
IPAddress ip;
|
||||
|
||||
Process _process;
|
||||
_process.begin("cat");
|
||||
_process.addParameter(broker_file); // for ssh remotely set broker address
|
||||
_process.run(); // run the process and wait for its termination
|
||||
String b;
|
||||
while (_process.available() > 0) {
|
||||
char c = _process.read();
|
||||
b += c;
|
||||
}
|
||||
b.trim();
|
||||
|
||||
if (ip.fromString(b.c_str())) prop->setBrokerIpAddress(ip);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
## 6. Examples
|
||||
The library comes with a number of example sketches. See **File > Examples > ArduinoProps** within the Arduino IDE application.
|
||||
|
||||
