Скачать или смотреть STM32 based motor controller - Reading ADC - Plotting Data with python

This is update video of my current motor controller project.

I had lot of problems on setting adc readings correctly and aligning them with motor pwm. Solution that i found was starting to use center aligned PWM and triggering ADC conversion on the center of every pulse. This ensures that mosfet is ON when ADC is read and worst noise can be eliminated from signal.

STMonitor was not fast enough, it was only supporting 1000 samples/second, and since i am reading 24k samples / second / channel, so in STMonitor data was looking too good because it was missing so much details/noise because low datarate. Instead of SWDIO debugging i started to use USB and custom datapackets that can be read with python script in real time.

In video i am currently plotting current_a value that is measured from phase a low shunt resistor.

Next update is adding all other ADC channels to the plotting, and starting look how i want to filter values.

At some point i would like to make better UI on C# for controlling, but now i will just use python because it is so fast to implement.
