DAC channels conversion are configured to be triggered by TIM2 TRGO with triangle wave generation. 12bit right data alignment is selected since we choose to access both DAC_DHR12R1 and DAC_DHR12R2 registers. A triangle amplitude of 2047 is selected for DAC channel1 and 1023 for DAC channel2. Both DAC channels are then enabled. DAC Channel1 DHR12R1 and DAC channel2 DHR12R2 registers are set to have a base output voltage of VREF/16 on each output. Once TIM2 is enabled, each TIM2 TRGO update event trigger both DAC channels start of conversion. The triangle counter is incremented, added to the base value and applied to the corresponding DAC channel output. The same calculation is repeated on each trigger. The triangle waves can be visualized by connecting both PA.04 and PA.05 pins to an oscilloscope. @par Directory contents - DAC/TwoChannels_TriangleWave/stm32f10x_conf.h Library Configuration file - DAC/TwoChannels_TriangleWave/stm32f10x_it.c Interrupt handlers - DAC/TwoChannels_TriangleWave/stm32f10x_it.h Header for stm32f10x_it.c - DAC/TwoChannels_TriangleWave/main.c Main program - DAC/TwoChannels_TriangleWave/system_stm32f10x.c STM32F10x system source file @par Hardware and Software environment - This example runs on STM32F10x Connectivity line, High-Density, XL-Density, Medium-Density Value line, High-Density Value line and Low-Density Value line Devices. - This example has been tested with STMicroelectronics STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line), STM32100E-EVAL (High-Density Value 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 and PA.05 pins to an oscilloscope @note JP2 should be open - STM3210C-EVAL Set-up - Only PA.04 can be monitored on an oscilloscope, PA.05 is used by other module (Motor control connector) that prevents to have DAC channel output on it. However, if you don't use Motor control connector, you can remove the 0ohm resistor R84 and thus PA.05 can be used for DAC output. @note Make shure that jumper JP15 is open. - STM3210E-EVAL Set-up - Connect PA.04 and PA.05 pins to an oscilloscope - STM32100E-EVAL Set-up - Connect PA.04 and PA.05 pins 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 *** 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. *
