This implementation output the printf message on the Hyperterminal using USART6. The USARTx 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 - "inc": contains the project firmware header files - inc/stm32f4xx_conf.h Library Configuration file - inc/stm32f4xx_it.h Interrupt handlers header file - "src": contains the project firmware source files - src/system_stm32f4xx.c STM32F4xx system clock configuration file - src/stm32f4xx_it.c Interrupt handlers - src/main.c Main program @note The "system_stm32f4xx.c" is generated by an automatic clock configuration tool and can be easily customized to your own configuration. To select different clock setup, use the "STM32F4xx_Clock_Configuration_V1.0.0.xls" provided with the AN3988 package available on <a href="http://www.st.com/internet/mcu/family/141.jsp"> ST Microcontrollers </a> @par Hardware and Software environment - This example has been tested with the following environment: - STM32F4DISCOVERY board - STM32F4DIS-BB for the Base Board - Hyperterminal - Software development tools - EWARM V6.40 - MDK-ARM V4.60 - Hardware Set-up - Mount STM32F4DISCOVERY board onto STM32F4DIS-BB board through CON1 and CON2 - Connect a null-modem female/female RS232 cable between the DB9 connector COM1 (USART6) and PC serial port @note Make sure that jumper JP1: ON JP2: ON - Connect the STM32F4DISCOVERY board to a PC with a 'USB type A to Mini-B' cable through USB connector CN1 to power the board. - Hyperterminal configuration: - Word Length = 8 Bits - One Stop Bit - No parity - BaudRate = 115200 baud - flow control: None @par How to use it ? In order to load the Project code, you have do the following: - EWARM - Open the Project.eww workspace - Rebuild all files: Project->Rebuild all - Load project image: Project->Debug - Run program: Debug->Go(F5) - MDK-ARM - Open the Project.uvproj project - Rebuild all files: Project->Rebuild all target files - Load project image: Debug->Start/Stop Debug Session - Run program: Debug->Run (F5) /*********** Portions COPYRIGHT 2012 Embest Tech.
