Example description
===================
This example provides a description of how to use the USART with hardware flow
control and communicate with the Hyperterminal.
First, the USART2 sends the TxBuffer to the hyperterminal and still waiting for
a string from the hyperterminal that you must enter which must end by '\r'
character (keypad ENTER button). The communication will end if received data exceed
255 without sending the '\r' character. Each byte received is retransmitted to the
Hyperterminal.
The string that you have entered is stored in the RxBuffer array. The receive
buffer have a RxBufferSize bytes as maximum.
The USART2 is configured as follow:
- BaudRate = 115200 baud
- Word Length = 8 Bits
- One Stop Bit
- No parity
- Hardware flow control enabled (RTS and CTS signals)
- Receive and transmit enabled
Directory contents
==================
platform_config.h Evaluation board specific configuration file
stm32f10x_conf.h Library Configuration file
stm32f10x_it.h Interrupt handlers header file
stm32f10x_it.c Interrupt handlers
main.c Main program
Hardware environment
====================
This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
boards and can be easily tailored to any other hardware.
To select the STMicroelectronics evaluation board used to run the example, uncomment
the corresponding line in platform_config.h file.
+ STM3210B-EVAL
- Connect a null-modem female/female RS232 cable between CN5 and PC serial
port.
- Note: in this case USART2 Tx, Rx, RTS and CTS pins are remapped by software
on PD.05, PD.06, PD.04 and PD.03 respectively.
+ STM3210E-EVAL
- Connect a null-modem female/female RS232 cable between CN8 and PC serial
port.
- Make sure the Jumper 4 (JP4) is in position 2<-->3.
+ Hyperterminal configuration:
- Word Length = 8 Bits
- One Stop Bit
- No parity
- BaudRate = 115200 baud
- flow control: Hardware
How to use it
=============
In order to make the program work, you must do the following :
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files :
+ stm32f10x_lib.c
+ stm32f10x_usart.c
+ stm32f10x_gpio.c
+ stm32f10x_nvic.c
+ stm32f10x_rcc.c
+ stm32f10x_flash.c
- Link all compiled files and load your image into target memory
- Run the example
