wukong board - does anyone know the byte "maps" for the device

Hi

i bought the wukong breakout board

i’m looking at the code behind [pxt-wukong here](https://github.com/zhouF96/pxt-longanbit/blob/4744e5758f5ee9052fc9652ce0852fbea85b0e2e/main.ts#L343]

does anyone know all the i2cread/i2cwrite combinations i can send to the wukong device?

e.g. to send an angle to Servo0 i can send

buf[0] = 0x03

buf[1] = angel;
buf[2] = 0;
buf[3] = 0;
pins.i2cWriteBuffer(board_address, buf);

how would i read this angle back with i2cReadBuffer() ?
