Your workbench

• Arduino IDE 2.2.1
• Simple FOC 2.3.3 installed
• esp32 3.0.2 installed

I have set the board on the arduino IDE to ESP32 Thing Plus C as suggested in the Hookup guide by Sparkfun (https://docs.sparkfun.com/SparkFun_IoT_Brushless_Motor_Driver/software_overview/)

Steps to reproduce

Simply having the above installed and trying to verify/upload the code

Hello,

Luckily I was able to both reproduce and fix the issue that you were seeing. Simply update your Simple FOC library to the latest: 2.3.4, more details follow. In your output, it's clear that it's an issue with the "Simple FOC" library. When I installed version 2.3.3 (thanks for listing your version there) I was able to see the problem:

Shown below:

Checking the Simple FOC 2.3.4 release, I see that they mention new support for the MCPWM driver. Which is why when I use 2.3.4, I no longer see the error:

I know the images aren't great, but I hope that helps.

Thanks!

Brilliant! Thank you very much for getting back to me. What convenient timing with the FOC update!
