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 +by DMA and stored in RxBuffer1 then compared with the send 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 by DMA and stored in RxBuffer2 then compared with the send 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_Polling/platform_config.h Evaluation board specific configuration file + - USART/DMA_Polling/stm32f10x_conf.h Library Configuration file + - USART/DMA_Polling/stm32f10x_it.h Interrupt handlers header file + - USART/DMA_Polling/stm32f10x_it.c Interrupt handlers + - USART/DMA_Polling/main.c Main program + - USART/DMA_Polling/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_Polling/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 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 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. + + * <h3><center>© COPYRIGHT 2011 STMicroelectronics</center></h3> + */ |
