- ##### Initialization and Configuration functions #####
- ===============================================================================
- [..]
- This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
- in asynchronous mode.
- (+) For the asynchronous mode the parameters below can be configured:
- (++) Baud Rate
- (++) Word Length
- (++) Stop Bit
- (++) Parity: If the parity is enabled, then the MSB bit of the data written
- in the data register is transmitted but is changed by the parity bit.
- (++) Hardware flow control
- (++) Receiver/transmitter modes
- (++) Over Sampling Method
- (++) One-Bit Sampling Method
- (+) For the asynchronous mode, the following advanced features can be configured as well:
- (++) TX and/or RX pin level inversion
- (++) data logical level inversion
- (++) RX and TX pins swap
- (++) RX overrun detection disabling
- (++) DMA disabling on RX error
- (++) MSB first on communication line
- (++) auto Baud rate detection
- [..]
- The HAL_RS485Ex_Init() API follows the UART RS485 mode configuration
- procedures (details for the procedures are available in reference manual).
-
-@endverbatim
-
- Depending on the frame length defined by the M1 and M0 bits (7-bit,
- 8-bit or 9-bit), the possible UART formats are listed in the
- following table.
-
- Table 1. UART frame format.
