First, the USART1 is configured to WakeUp from STOP with StartBitMethod(when any data is received on RX line). After configuration, the MCU enters STOP mode and waits to be waken. When a string is sent to USART1 via the hyperterminal, the MCU WakeUp from stop, restore the system clock configuration and configures the systick to toggle LED's. The LED's toggling is used to indicate that the MCU is Waken Up from stop. The USART1 is configured as follow: - BaudRate = 115200 baud - Word Length = 8 Bits - One Stop Bit - No parity - Hardware flow control disabled (RTS and CTS signals) - Receive and transmit enabled @par Directory contents - USART/USART_WakeUpFromStop/stm32f0xx_conf.h Library Configuration file - USART/USART_WakeUpFromStop/stm32f0xx_it.c Interrupt handlers - USART/USART_WakeUpFromStop/stm32f0xx_it.h Interrupt handlers header file - USART/USART_WakeUpFromStop/main.c Main program - USART/USART_WakeUpFromStop/main.h Main program header file - USART/USART_WakeUpFromStop/system_stm32f0xx.c STM32F0xx system source file @note The "system_stm32f0xx.c" is generated by an automatic clock configuration tool and can be easily customized to meet user application requirements. To select different clock setup, use the "STM32F0xx_Clock_Configuration_VX.Y.Z.xls" provided with the AN4055 package available on ST Microcontrollers @par Hardware and Software environment - This example runs on STM32F0xx Devices. - This example has been tested with STMicroelectronics STM320518-EVAL (STM32F0xx) evaluation board and can be easily tailored to any other supported device and development board. - STM320518-EVAL Set-up - Connect a null-modem female/female RS232 cable between the DB9 connector CN7 and PC serial port. - Make sure that JP3 is in position 5<->6 - Hyperterminal configuration: - BaudRate = 115200 baud - Word Length = 8 Bits - One Stop Bit - No parity - flow control: None @par How to use it ? In order to make the program work, you must do the following : - Copy all source files from this example folder to the template folder under Project\STM32F0xx_StdPeriph_Templates - Open your preferred toolchain - Rebuild all files and load your image into target memory - Run the example *
