First, the USART1 and USART2 address are set to 0x1 and 0x2. The USART1 send continusouly the character 0x33 to the USART2. The USART2 toggle a LED connected to the PC.06, PC.07, PC.08 and PC.09 pins while receiving 0x33. When a falling edge is applied on EXTI line9, an interrupt is generated and in the EXTI9_5_IRQHandler routine, the USART2 is entred in mute mode and still in this mode (no LED toggling) until a rising edge is applied on EXTI Line 0 occured. In this interrupt routine the USART1 send the character of address mark (0x102) to wakeup USART2. The LED restart toggling. USART1 and USART2 configured as follow: - BaudRate = 9600 baud - Word Length = 9 Bits - One Stop Bit - No parity - Hardware flow control disabled (RTS and CTS signals) - Receive and transmit enabled 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_Rx(PD.05) and USART1_Rx(PA.10) to USART2_Tx(PD.06) (in the STM3210B-EVAL board, connect a null-modem female/female RS232 cable between CN5 and CN6). - Connect four led to pin PC.06, PC.07, PC.08 and PC.09 (LD1, LD2, LD3 and LD4 on STM3210B-EVAL board). - Connect a push-button to pin PB.09 (EXTI Line9) (Key push-button on STM3210B-EVAL board). - Connect a push-button to pin PA.00 (EXTI Line0) (Wakeup push-button on STM3210B-EVAL board). 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 + stm32f10x_exti.c - Link all compiled files and load your image into either RAM or Flash - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE******
