Hi

i bought the [wukong breakout board](https://www.elecfreaks.com/learn-en/microbitExtensionModule/wukong.html)

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