I want to use RTC (RX-8571) for I2C communication with STM32WLE5JC. I wrote the code using [HAL_I2C_Master_Transmit] and [HAL_I2C_Master_Receive], but I can only send the device address of the first byte. The errata says "Write the first data in I2C_TXDR", but I don't know how to write it. Please help me.
