AS A RESULT, STMICROELECTRONICS SHALL NOT BE HELD LIABLE FOR ANY * DIRECT, INDIRECT OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY CLAIMS ARISING * FROM THE CONTENT OF SUCH FIRMWARE AND/OR THE USE MADE BY CUSTOMERS OF THE * CODING INFORMATION CONTAINED HEREIN IN CONNECTION WITH THEIR PRODUCTS. ****************************************************************************** @endverbatim @par Example Description This example provides a basic communication between USARTy and USARTz using DMA capability, flags and interrupts. USARTy and USARTz can be USART1 and USART2 or USART2 and USART3, depending on the STMicroelectronics EVAL board you are using. First, the DMA transfers data from TxBuffer2 buffer to USARTz Transmit data register, then this data is sent to USARTy. Data received by USARTy is transferred using RXNE flag and stored in RxBuffer1 then compared with the sent ones and the result of this comparison is stored in the "TransferStatus1" variable. In the same time, the DMA transfers data from TxBuffer1 buffer to USARTy Transmit data register, then this data is sent to USARTz. Data received by USARTz is transferred using Receive interrupt and stored in RxBuffer2 then compared with the sent ones and the result of this comparison is stored in the "TransferStatus2" variable. USARTy and USARTz configured as follow: - BaudRate = 230400 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/DMA_Interrupt/platform_config.h Evaluation board specific configuration file - USART/DMA_Interrupt/stm32f10x_conf.h Library Configuration file - USART/DMA_Interrupt/stm32f10x_it.h Interrupt handlers header file - USART/DMA_Interrupt/stm32f10x_it.c Interrupt handlers - USART/DMA_Interrupt/main.c Main program - USART/DMA_Interrupt/system_stm32f10x.c STM32F10x system source file @par Hardware and Software environment - This example runs on STM32F10x Connectivity line, High-Density, High-Density Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density and Low-Density Value line Devices. - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density Value line), 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 USART/DMA_Interrupt/platform_config.h file - STM32100E-EVAL Set-up - Connect a null-modem female/female RS232 cable between CN10 (USART1) and CN5 (USART2). @note Make sure that jumper JP5 is not open. - STM32100B-EVAL Set-up - Connect a null-modem female/female RS232 cable between CN10 (USART1) and CN9 (USART2). @note In this case USART2 Tx and Rx pins are remapped by software on PD.05 and PD.06 respectively. - STM3210C-EVAL Set-up - Connect USART2 Tx pin (PD.05) to USART3 Rx pin (PC.11) - Connect USART2 Rx pin (PD.06) to USART3 Tx pin (PC.10) @note In this case USART3 Tx and Rx pins are remapped by software. Make sure that jumpers JP19 and JP18 are open. - STM3210E-EVAL Set-up - Connect a null-modem female/female RS232 cable between CN12 (USART1) and CN8 (USART2). - STM3210B-EVAL Set-up - Connect a null-modem female/female RS232 cable between CN6 (USART1) and CN5 (USART2). - In this case USART2 Tx and Rx pins are remapped by software on PD.05 and PD.06 respectively. @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\STM32F10x_StdPeriph_Template - Open your preferred toolchain - Rebuild all 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 *** and 128 Kbytes. - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers where the Flash memory density ranges between *** and 128 Kbytes. - High-density Value line devices are STM32F100xx microcontrollers where the Flash memory density ranges between 256 and 512 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. *
