Hello Community, I'm currently working on a project that involves controlling stepper motors at high speeds using an ESP32 board with built-in WiFi. However, I'm facing issues with the ESP32 WROOM 32 Dev Module, as it is unable to run the motors properly alongside WiFi communication. I'm now looki…

I am building a differential drive rc robot. Stepper motor runs upto 7000steps/s and both motors at different speeds. Hardware: esp32 Wroom 32, li-ion cells, drv8825 stepper driver, nema 17 stepper motor Here is the code: davinci_robot/drv_stepper_test.ino at main · robofuntastic/davinci_robot · G…

[image] robofuntastic: I am using Accelstepper library for motors ... If we remove WiFi code and remove FreeRTOS part then it works great Maybe easier to use MobaTools instead. MobaTools creates the steps by timer interrupts in the background. So you don't have to bother with step creation …

I will try that library and inform you about the results. If I use that library with FreeRTOS, will that be an issue?

[image] robofuntastic: If I use that library with FreeRTOS, will that be an issue? I never tried it, but I don't think so.

That library did not work i tried it with FreeRTOS it just jams the motor and does not move

I edited the ESP32Web example and added a simple RTOS task running in parallel ( printing to the Serial line every second ) and it worked. What may be a problem is running MobaTools from different tasks in parallel. MobaTools methods are not written to be re-entrant. I tried that and it worked, bu…

Alright may be there could be problem with my code I have discussed it with a professional He said that its not a good idea to use the interrupts with FreeRTOS. Our application cannot compromise over slow speed and also other task should also work smoothly. So we have decided to use 2 esp32 board…
