Dear expert
I am currently implementing the SMBUS communication with TI BQ40Z80 via STM32L431xxx + Middle ware.
However, when observing the smbus waveform, N byte block write does not work properly and block read is also strange.
Other register accesses of BQ40Z80 that operate with READ, BLOCK_WRITE cmnd_query operate normally.
I would like help with the middle ware stack interface argument.
-. cmnd_query , direction , piobuf = STACK_SMBUS_GetBuffer(..) implement.
cmnd_code = command code;
cmnd_query = BLK_PRC_CALL;
cmnd_master_Tx_size = tx_length;
cmnd_master_Rx_size = rx_length;
call STACK_SMBUS_HostCommand(....) function with direction = READ;
