Re: Help! ESP32 burnt by Motor Drive Module.

I have used this one, may not be what your looking for but it could prove out the issue because it has opto Isolators as inputs to protect your device.

Describe what your measuring with your A/D pin and anything attached to that pin.

Re: Help! ESP32 burnt by Motor Drive Module.

There is something that does not make sense here. I have done exactly the same thing as you. Not using the exact same parts mind you. But basically the same motor driver and motor. I never had a issue when I would reverse the motor direction. The control lines and PWM signal are input only to the mo...

Re: Help! ESP32 burnt by Motor Drive Module.

What would be more helpful it is give links to the exact modules you are using. And also what pins you have connected to them.

Re: RTOS running on one core only

But: polling an input-pin with CoopOS is much faster
Just curious why you would pole an input-pin rather than set a IRQ for it.

Re: Variable doesn't update between cores

You better just play it safe and get a wall wart that is 5v 1A. They can be had all over the place for a few dollars. While your at it you might want to get something like this to know what your actually using and the peaks. (NOTE: not saying to get this one, so do some homework on whats best for yo...

For myself, i can't help too much because its Arduino. But you should post your complete code for others to have a lookse

Re: Variable doesn't update between cores

Also I see in your code you have: #include "freertos/FreeRTOS.h" #include "freertos/task.h" Yes, this is not Arduino code. There are 2 primary ways to code for the ESP32. ESP-ADF and ESP-IDF. ADF is the Arduino side of things. Being Arduino, there is allot more things hidden from the user that is g...

Re: Variable doesn't update between cores

I appreciate your input. I thought since I had nothing in the loop that it took no resources. What should be put in Loop so that it doesn't bog the two tasks down? Will a delay command be all that is necessary? Loop is constantly running, granted there is nothing for it to do when its empty. But in...

Re: Variable doesn't update between cores

Why? Each task is assigned a different core. Both tasks should be running independently shouldn't they? Since they are on seperate cores I don't actually need anything in the loop correct? That would be true if you had 2 clock sources with one for each core. Think of it like you PC. you have multip...
