@par Example Description
|
|
|
|
Re-routing of the C library printf function to the UART.
|
|
The UART outputs a message on the HyperTerminal.
|
|
|
|
Board: STM32VL-Discovery
|
|
Tx Pin: PA.09
|
|
Rx Pin: PA.10

|_STM32_Board_____________|
|
|
|
|
The USART is configured as follows:
|
|
- BaudRate = 9600 baud
|
|
- Word Length = 8 Bits (7 data bit + 1 parity bit)
|
|
- One Stop Bit
|
|
- Odd parity
|
|
- Hardware flow control disabled (RTS and CTS signals)
|
|
- Reception and transmission are enabled in the time
|
|
|
|
@note USARTx/UARTx instance used and associated resources can be updated in "main.h"
|
|
file depending hardware configuration used.
|
|
|
|
@note When the parity is enabled, the computed parity is inserted at the MSB
|
|
position of the transmitted data.

@par Hardware and Software environment
|
|
|
|
- This example runs on STM32F100xB devices.
|
|
|
|
- This example has been tested with STM32VL-Discovery board and can be
|
|
easily tailored to any other supported device and development board.
|
|
|
|
- STM32_VL_DISCOVERY Set-up
|
|
- If you want to display data on the HyperTerminal, please connect USART1 TX (PA9)
|
|
to RX pin of PC serial port (or USB to UART adapter).
|
|
USART1 RX (PA10) could be connected similarly to TX pin of PC serial port.
|
|
|
|
- Hyperterminal configuration:
|
|
- Word Length = 7 Bits
|
|
- One Stop Bit
|
|
- Odd parity
|
|
- BaudRate = 9600 baud
|
|
- flow control: None
|
|
|
|
@par How to use it ?
|
|
|
|
In order to make the program work, you must do the following :
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
