A71CH Memory addresses

[ahmedtolba]

Hello,

I'm trying to interface with A71CH using STM32F Hal functions hal_mem_write.

 Which writes to a specific address with size, a byte of data command PCB. 

What are the adddresses and what it should be ?

The hal function definition is like that

HAL_StatusTypeDef HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout)

The device address is 0x48, but what should be the memAddress in A71CH ?

Hello,

A71CH's I2C interface is using the following I2C spec:

Please check with the ST tech supporter on how to use the Hal API to implement the timing.

Thanks for your patience and understanding!

Have a great day,
Kan
