Functions

void USART_SendData (USART_TypeDef *USARTx, uint16_t Data)
 Transmits single data through the USARTx peripheral.
uint16_t USART_ReceiveData (USART_TypeDef *USARTx)
 Returns the most recent received data by the USARTx peripheral.

Detailed Description

Data transfers functions. 

 ===============================================================================
                    ##### Data transfers functions #####
 ===============================================================================
    [..] This subsection provides a set of functions allowing to manage 
         the USART data transfers.
    [..] During an USART reception, data shifts in least significant bit first 
         through the RX pin. When a transmission is taking place, a write instruction to 
         the USART_TDR register stores the data in the shift register.
    [..] The read access of the USART_RDR register can be done using 
         the USART_ReceiveData() function and returns the RDR value.
         Whereas a write access to the USART_TDR can be done using USART_SendData()
         function and stores the written data into TDR.
