Hi Community,
I am trying to write and read data of 1 byte after the transaction of 1000 data of 1 byte through i2c_stm32_transfer() in i2c_ll_stm32.c, I am getting incorrect response (tx_data != rx_data) in I2C polling mode (controller). Is there a global buffer which is getting filled and not able to clear the contents, the pointer is stuck somewhere, or the data register is pre-occupied. What could be the possible reason? And what is the maximum no. of data bytes we can transfer in I2C Polling mode?
