This implementation output the printf message on the Hyperterminal using USARTx. USARTx can be USART1 or USART2 depending on the EVAL board you are using. 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 - USART/Printf/stm32f10x_conf.h Library Configuration file - USART/Printf/stm32f10x_it.h Interrupt handlers header file - USART/Printf/stm32f10x_it.c Interrupt handlers - USART/Printf/main.c Main program @par Hardware and Software environment - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, XL-Density, Medium-Density Value line, Low-Density and Low-Density Value line Devices. - This example has been tested with STMicroelectronics STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line), STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) evaluation boards and can be easily tailored to any other supported device and development board. To select the STMicroelectronics evaluation board used to run the example, uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL) - STM32100B-EVAL Set-up - Connect a null-modem female/female RS232 cable between the DB9 connector CN10 and PC serial port. - STM3210C-EVAL Set-up - Connect a null-modem female/female RS232 cable between the DB9 connector CN6 (USART2) and PC serial port. @note Make sure that jumpers JP19 and JP18 are open. - STM3210E-EVAL Set-up - Connect a null-modem female/female RS232 cable between the DB9 connector CN12(when USART1 is used) and PC serial port. - STM3210B-EVAL Set-up - Connect a null-modem female/female RS232 cable between the DB9 connector CN6(when USART1 is used) and PC serial port. - 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 make the program work, you must do the following : - Create a project and setup all project configuration - Add the required Library files : - stm32f10x_exti.c - stm32f10x_gpio.c - stm32f10x_rcc.c - stm32f10x_usart.c - stm32f10x_i2c.c - stm32f10x_spi.c - misc.c - stm32_eval.c (under Utilities\STM32_EVAL) - system_stm32f10x.c (under Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x) - Edit stm32f10x.h file to select the device you are working on. - Edit stm32_eval.h file to select the evaluation board you will use. @b Tip: You can tailor the provided project template to run this example, for more details please refer to "stm32f10x_stdperiph_lib_um.chm" user manual; select "Peripheral Examples" then follow the instructions provided in "How to proceed" section. - Link all compiled files and load your image into target memory - Run the example @note - Low-density Value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density Value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 512 and 1024 Kbytes. - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. * <h3><center>&copy; COPYRIGHT 2010 STMicroelectronics</center></h3> */
