Keyboard Interrupt on UART receive

[StanCosgrove]

Hi i m using 26 keyboard key to interrupt via UART received, should i coded the 26 interrupt in a single rxcplt callback function or a multiple callback function? Whats the best way? pls advise...

void HAL_UART_RxCpltCallback(UART....)

{

  HAL_UART_Receive_IT(huart, &rx_data....)

  if (rx_data  == 'a')

....

  if (rx_data == 'b')

...

if (rx_data == 'c')

}

I've updated the code to show how to check for each character, at least for abc. Just do the same for the rest of the alphabet.
