First, the USART1 sends data from TxBuffer1 buffer to USART2 using TXE flag. Data received using RXNE flag by USART2 is stored in RxBuffer2 then compared with the sent ones and the result of this comparison is stored in the "TransferStatus1" variable. Then, the USART2 sends data from TxBuffer2 buffer to USART1 using TXE flag. Data received using RXNE flag by USART1 is stored in RxBuffer1 then compared with the sent ones and the result of this comparison is stored in the "TransferStatus2" variable. USART1 and USART2 configured as follow: - BaudRate = 230400 baud - Word Length = 8 Bits - One Stop Bit - Even parity - Hardware flow control disabled (RTS and CTS signals) - Receive and transmit enabled - USART Clock disabled - USART CPOL: Clock is active low - USART CPHA: Data is captured on the second edge - USART LastBit: The clock pulse of the last data bit is not output to the SCLK pin Directory contents ================== stm32f10x_conf.h Library Configuration file stm32f10x_it.h Interrupt handlers header file stm32f10x_it.c Interrupt handlers main.c Main program Hardware environment ==================== Connect USART1_Tx(PA.09) to USART2_Tx(PD.05) and connect a pull-up resistor to this line (10K). 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_gpio.c + stm32f10x_rcc.c + stm32f10x_usart.c + stm32f10x_nvic.c + stm32f10x_flash.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE******
