                I working on USART in stm32f0-discovery board, in that USART keeps on sending a character 'c'..But i intended to write a code it sends the character 'c' whenever it receives 'a' ....Why it is happening like tat, my code is

void usart_access(void)
             unsigned char ab=USART_ReceiveData(USART2);
             if(ab == 'a')
                  while (USART_GetFlagStatus(USART2, USART_FLAG_RXNE) == RESET);

The USART_access function called in the while(1) loop.
