DAC channel1 is then enabled. Once TIM6 is enabled, each TIM6 TRGO update +event generate a DMA request which transfer data to the DAC1 register and DAC +conversion is started. The escalator signal can be visualized by connecting PA.04 +pin to an oscilloscope. + +@par Directory contents + + - DAC/OneChannelDMA_Escalator/stm32f10x_conf.h Library Configuration file + - DAC/OneChannelDMA_Escalator/stm32f10x_it.c Interrupt handlers + - DAC/OneChannelDMA_Escalator/stm32f10x_it.h Header for stm32f10x_it.c + - DAC/OneChannelDMA_Escalator/main.c Main program + - DAC/OneChannelDMA_Escalator/system_stm32f10x.c STM32F10x system source file + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, XL-Density, + High-Density Value line, Medium-Density Value line and Low-Density Value + line Devices. + + - This example has been tested with STMicroelectronics STM32100B-EVAL + (Medium-Density Value line),STM32100E-EVAL (High-Density Value line), + STM3210C-EVAL (Connectivity line) and STM3210E-EVAL (High-Density and + XL-Density) evaluation boards and can be easily tailored to any other + supported device and development board. + + - STM32100B-EVAL Set-up + - Connect PA.04 pin to an oscilloscope + @note Make shure that jumper JP2 is open. + + - STM3210C-EVAL Set-up + - Connect PA.04 pin to an oscilloscope + @note Make shure that jumper JP15 is open. + + - STM3210E-EVAL Set-up + - Connect PA.04 pin to an oscilloscope + + - STM32100E-EVAL Set-up + - Connect PA.04 pin to an oscilloscope + +@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> + */ |
