|
|
Re-routing of the C library printf function to the UART.
|
||
|
|

|_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 STM32F107xC devices.
|
||
|
|
|
||
|
|
- This example has been tested with STM3210C-EVAL RevC board and can be
|
||
|
|
easily tailored to any other supported device and development board.
|
||
|
|
|
||
|
|
- STM3210C_EVAL Set-up
|
||
|
|
- Connect a null-modem female/female RS232 cable between the DB9 connector
|
||
|
|
CN6 (USART2) and PC serial port if you want to display data on the HyperTerminal.
|
||
|
|
@note Make sure that jumper JP16 is 2-3 position (USART2_RX).
|
||
|
|
|
||
|
|
- 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
