@sconstan Hi, I was working on that. I have a version of CanAirIO Firmware working with Home Assistant. And now CanAirIO Firmware support M5StickCPlus M5AtomLite and M5CoreInk. Maybe I think is possible that works with M5 Core2

Home Assistant Support

• Home Assistant first release. PR #153
• Anaire improvements and clouds refactors
• battery level primitives on BLE, InfluxDB and MQTT clouds
• new BMP680 sensor and some Sensorslib improvements
• Refactor main_value and device_type from Sensorslib

AIRobot

ESP32 robot platform, the idea is join it with a MaxiPy RISC-V camera. For now the current development works with a M5StickC Joystick hat that controlling the robot via UDP using protobuf (nanopb). In the robot it use a simple ESP32 board.

TODO

• Platformio project (two sources)
• UDP channel settings in preferences lib
• nanopb (protocol buffers implementation) for joystick messages
• separated OTA (joystick and robot)
• MQTT channel ?
• SPI connection to MaxiPy nano camera
• Push AI models via proto
• Auto navegation
• Seek and destroy objects

Firmware

You can build it with Arduino IDE renaming the main files to .ino, but it is more easy if you use PlatformIO, with a simple command you upload both, Joystick and Robot.

pio run --target upload

Please check the right USB ports on platformio.ini file.

After the first upload, you could comment the robot and joystick blocks in platformio.ini and uncomment the OTA blocks for upload via WiFi without USB.

Usage

Turn on the robot, then the joystick, when the joystick detect the robot, push the M5 button for some seconds for pair. For turn off the joystick press again the M5 button.

DIY Robot demo

For the instructions and more details here.

Hi everyone, I wrote a example that extend the clock to a NTP clock (using a time service to sync it) and other features, the idea is improve it and add more features.

Features

• eInk display refresh without any blink
• shutdown with RTC implementation
• run time is only 2 sec each minute
• NTP sync beep confirmation
• added implementation for ENVII hat (disabled for default)
• detecting USB charging (toggle partial update/full refresh in battery mode)
• Clock features on Left/Right wheel button

Source code and contributions

Source code (PlatformIO, Arduino compatible)

@m5stack said in How to get Device infos from m5stack Devices:

you could refer to this program to get the battery status info:

https://github.com/m5stack/M5StickC/tree/master/examples/Basics/AXP192

but before you compile it. you need to download the M5StickC-Plus lib for you device. and change the program include code.

Hi, thanks for you answer,

But is secure that use this files, the AXP192 library files from StickC in the CoreInk board? I did see that in axp.begin() method you enable some voltages but the board is different, maybe I could be damage my CoreInk?
