JoyC is a rocker module designed for the M5StickC.It supports two-hand operation. Embedded STM32F030F4 main control chip, using I2C communication protocol and host M5StickC for data transmission. The range of the joystick is 0~200, there are 12 RGB LEDs under the left and right joysticks, and the bottom of the joystick is equipped with a 16340 battery base for continuous battery life.
I2C address: 0x38
The library isn`t updated through the arduino IDE, download latest version from https://github.com/m5stack/M5StickC and update it manually, probably will be fixed soon.
I'm using it with Blockly. It generate a 0 to 200 signal on each axis.
For now it's a reliable product.
