##### How to use this driver #####
|
|
===============================================================================
|
|
[..]
|
|
The Extended UART HAL driver can be used as follows:
|
|
|
|
(#) Declare a UART_HandleTypeDef handle structure.
|
|
|
|
(#) For the UART RS485 Driver Enabled mode, initialize the UART registers
|
|
by calling the HAL_RS485Ex_Init() API.

This subsection provides a set of functions allowing to initialize the USARTx or the UARTy
|
|
in asynchronous mode.
|
|
(+) For the asynchronous mode only these parameters 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.
|
|
Depending on the frame length defined by the M bit (8-bits or 9-bits),
|
|
the possible UART frame formats are as listed in the following table:
|
|
|-----------|-----------|---------------------------------------|
|
|
| M1M0 bits | PCE bit | UART frame |
|
|
|-----------------------|---------------------------------------|
|
|
| 00 | 0 | | SB | 8-bit data | STB | |
|
|
|-----------|-----------|---------------------------------------|
|
|
| 00 | 1 | | SB | 7-bit data | PB | STB | |
|
|
|-----------|-----------|---------------------------------------|
|
|
| 01 | 0 | | SB | 9-bit data | STB | |
|
|
|-----------|-----------|---------------------------------------|
|
|
| 01 | 1 | | SB | 8-bit data | PB | STB | |
|
|
+---------------------------------------------------------------+
|
|
| 10 | 0 | | SB | 7-bit data | STB | |
|
|
|-----------|-----------|---------------------------------------|
|
|
| 10 | 1 | | SB | 6-bit data | PB | STB | |
|
|
+---------------------------------------------------------------+
|
|
(++) 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_LIN_Init() and HAL_RS485Ex_Init() APIs follows respectively the LIN and
|
|
the UART RS485 mode configuration procedures (details for the procedures are
|
|
available in reference manual).

detection length to more than 4 bits for multiprocessor address mark wake up.
|
|
(+) HAL_UART_EnableStopMode() API allows the UART to wake up the MCU from Stop mode as

long as UART clock is HSI or LSE
|

(+) HAL_UART_DisableStopMode() API disables the above feature

|
wake-up event is the address match feature
|
