Hi everyone, I'm new to MCUs and programming in general and currently trying to calculate the average of the plateaus from 3 ADC input channels. I'm using Exponential Smoothing to reduce the noise and an algorithm to detect the plateau. Even tho my s...

Signals are similar across all 12 channels but I'm confused about how to run the averaging algorithm for 12 channels at the same time. Currently, I can get the ADC values from all 12 channels using DMA without the averaging process.To explain further...

Thanks for the suggestions. Actually the interrupt priority for SysTick and DMA Callback were the same and after lowering the DMA priority (higher numeric value) everything worked as expected. There're definitely other improvement possible in terms ...

> In what way?I get lower voltage values than expected. My sensor runs/scans for a certain amount of time and the number of plateaus are also known. So, I'm guessing the delay function doesn't work with the current implementation. Because, when I run...

Idk, now it's not even visible for me as well. I've uploaded it here: https://ibb.co/whW5b1Y

Thanks for the suggestion. I have a MATLAB algorithm for detecting plateaus from this signal but I'm having difficulties implementing the same algorithm for 12 channels with STM32. But the MATLAB algorithm is also not perfect. So, I'm looking for oth...

Thanks for the suggestion. The signal looks like this and I want to detect and calculate the average (of N samples) for each plateau.

Using HAL_Delay inside the DMA callback

Hi everyone, I'm a beginner with MCUs. I want to read ADC values from 12 channels continuously and I'd like to implement an averaging process before transmitting them through UART. I'm using Nucleo-L476RG.
