In STM32F407, the The DAC output channels support a low power mode, the Sample and Hold mode. We can proceed programming as like in Arduino. Contribute to eziya/STM32F4_HAL_EXAMPLES development by creating an account on GitHub. That works pretty well, but I am quite disappointed that one cannot setup a waveform in a memory location from wich the DMA would feed the data into the DAC automatically, without the involvement of the processor. A chorus effect is generated by mixing a Signal with varying delay(0-30ms) to the original one. 14. You've only got 66 microseconds to sample, calculate and output. ino file or the README. Earlier, we learned about Analog-to-Digital Converters like ADS1115 as well as you have two DAC boards connected to the same SDA/SCL I2C bus pins.
