Hi ,
I am trying to implement UART with interupt control in my system , and trying to print the sent and received data on PC terminal via a micro-usb port. In my system UART is working great in polling mode. I am using STM32F415RG, when I am using these APIs like HAL_UART_Transmit_IT and HAL_UART_Receive_IT, I am getting HAL_Busy as a return error, and I don't see any msgs on terminal.
I have tried looking for some online code for reference and most of them are using APIs like RCC_APB2PeriphClockCmd RCC_AHB1PeriphClockCmd
I tried to implement this in my code, but it gives compilation error, I couldn't find the respective driver file for these APIs.
Please let me know what needs to done in this case, I can share my code if you want to take a look at it.
