How can I do three channel A2D in single conversion mode ? There are lots of examples using continuous mode but none for single conversion mode. In this tutorial we will see that it's possible to retrieve data from a potentiometer and send them in an array. To monitor multiple channels we need to use DMA to update a memory array with the sampled values. At the moment I simply want to obtain an input value (ConvertedValue) as a variable rather than saving to memory in DMA. Separate voltage regulator for the Analog part, which allow the ADC to be read correctly without the digital noise pickup. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4. Hello, ? i think the issue with the difference between expected results and the reached results is regarding that in the FIR example has floating point input format, and in your case the ADC give a int format data, so you need to convert that into voltage floating. The DMA is a great tool to use with the ADC when you want to transfer lots of samples to memory continuously.
