Development notes

• If you start a new Platformio project, use:

# put this line in platformio.ini :
monitor_speed = 115200 
# to fix could not open port /dev/ttyUSB0: [Errno 13] Permission denied: '/dev/ttyUSB0', open terminal and write:
sudo chmod a+rw /dev/ttyUSB0

Tools used:

• Platformio (https://platformio.org)
• VScode (https://code.visualstudio.com)
• ESP-IDF (https://docs.espressif.com/projects/esp-idf/en/stable/get-started/)
• M5StickC , but you can use other dev board:
  • For the Detailed documentation of M5StickC, please click here
  • In order to buy M5StickC, please click here
  • Description: M5StickC is a ESP32 development board with 0.96 inch TFT color screen (80 * 160 resolution), Red LED, button, Microphone, IR transmitter, 6-axis IMU (SH200Q) and 80 mAH battery. The ESP32 module ESP32-Pico in M5StickC also has a built-in 4MB flash. If the M5StickC is equipped with watch-base and watch-belt, you can wear it on your wrist.
