Workflow

Setup Local

cd ESP32_ZACUS
python3 -m venv .venv
source .venv/bin/activate
pip install platformio esptool pyserial

# List PlatformIO boards
pio boards | grep freenove

Build & Upload Freenove

pio run -e freenove_esp32s3_full_with_ui -t upload --upload-port /dev/cu.usbmodem5AB90753301

Serial Monitor (115200 baud)

pio device monitor -p /dev/cu.usbmodem5AB90753301 -b 115200

Or Python:

python3 << 'PY'
import serial, time
port = '/dev/cu.usbmodem5AB90753301'
ser = serial.Serial(port, 115200, timeout=0.5)
time.sleep(0.2)
ser.write(b'STATUS\n')
time.sleep(0.3)
for _ in range(10):
    line = ser.readline().decode('utf-8', 'ignore').strip()
    if line:
        print(line)
ser.close()
PY

Future Work

UI Optimization (ui_freenove_allinone):
- Refactor LVGL rendering pipeline
- Scene/story integration improvements
- Touch input handling; audio trigger feedback
Story Engine (lib/story/):
- Performance audit
- Memory footprint reduction
- ESP-NOW sync protocol optimization
Hardware Integration:
- Audio codec I2S optimization
- PSRAM buffer management
- Camera/WiFi/Bluetooth coexistence

Git Push to GitHub

Once repo created on GitHub:

cd ESP32_ZACUS
git remote add origin https://github.com/YOUR_USER/ESP32_ZACUS.git
git branch -m master main
git push -u origin main
