When the user presses the KEY push-button, DMA transfers the two selected waveforms to the DAC. For each press on KEY button, 2 signals has been selected and can be monitored on the two DAC channels: - Escalator waveform (Channel 1) and Sine waveForm (Channel 2). - Noise waveform (Channel 1) and Triangle waveform (Channel 2). @par Directory contents - DAC/DAC_SignalsGeneration/stm32f4xx_conf.h Library Configuration file - DAC/DAC_SignalsGeneration/stm32f4xx_it.c Interrupt handlers - DAC/DAC_SignalsGeneration/stm32f4xx_it.h Interrupt handlers header file - DAC/DAC_SignalsGeneration/main.c Main program - DAC/DAC_SignalsGeneration/main.h Main program header file - DAC/DAC_SignalsGeneration/system_stm32f4xx.c STM32F4xx system source file @note The "system_stm32f4xx.c" is generated by an automatic clock configuration tool and can be easily customized to your own configuration. To select different clock setup, use the "STM32F4xx_Clock_Configuration_V1.1.0.xls" provided with the AN3***8 package available on ST Microcontrollers @par Hardware and Software environment - This example runs on STM32F40xx/STM32F41xx, STM32F427x/STM32F437x Devices. - This example has been tested with STMicroelectronics STM324xG-EVAL (STM32F40xx/ STM32F41xx Devices) and STM32437I-EVAL (STM32F427x/STM32F437x Devices) evaluation boards and can be easily tailored to any other supported device and development board. - STM324xG-EVAL and STM32437I-EVAL Set-up - Use KEY push-button connected to PG15. - Connect PA4 (DAC Channel1) and PA5 (DAC Channel2) pins to an oscilloscope. - Make sure that JP31 is removed. @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\STM32F4xx_StdPeriph_Templates - Open your preferred toolchain - Rebuild all files and load your image into target memory - Run the example *
