Detailed Description
Half-duplex mode function.
=============================================================================== Half-duplex mode function =============================================================================== This subsection provides a set of functions allowing to manage the USART Half-duplex communication. The USART can be configured to follow a single-wire half-duplex protocol where the TX and RX lines are internally connected. USART Half duplex communication is possible through the following procedure: 1. Program the Baud rate, Word length, Stop bits, Parity, Mode transmitter or Mode receiver and hardware flow control values using the USART_Init() function. 2. Configures the USART address using the USART_SetAddress() function. 3. Enable the USART using the USART_Cmd() function. 4. Enable the half duplex mode using USART_HalfDuplexCmd() function. @note The RX pin is no longer used @note In Half-duplex mode the following bits must be kept cleared: - LINEN and CLKEN bits in the USART_CR2 register. - SCEN and IREN bits in the USART_CR3 register.
