I connect the L9110s Drive board directly to my 7.2v Battery(8.4v) to test. L9110s can handle 12V in its datasheet. Test about 3 minutes, the MPU and PS2Controller are good, but something wrong with the PWM controlling and my ESP32 is very hot. I disconnect the power immediately to save my ESP32. I ...

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. https://www.amazon.com/gp/product/B078TDKC4F/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 Thanks. This one seems to be a much bigger one. If I add a...

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 m...

More test, I narrow the error down to the power source and the motor. I got 4 N20 motors in hand, 2 are 300 rpm and the other 2 is 200rpm. I measure the electric resistance of them. One 300 rpm motor is 5.8Ω, the other motors are around 10.8~12.8Ω which explains why this 5.8Ω one is the fastest and ...

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.

Hi, my dev board is MH-ET ESP32 Mini Kit. I got issues by using PWM driving 2 N20 Motors(1:50, 6V). I've found that sometimes my robot reboot when the motor start or change its direction. So I make a simple programme to reproduce the error. Something like Blink Example, change 2 N20 Motor direction ...

Hi, I noticed there are pull-ups resistors on the L9110s x2 Motor Drive Module. And lately, I got a tiny L9110s Motor board which doesn't have the pull-ups. And I read the data-sheet of L9110s chips. No pull-ups in the example circuit. I'm generating the PWM by ledcWrite() and sigmaDeltaWrite() and ...

Thanks a lot. @ESP_Angus

Hi,
I'm using to restart my ESP32 by code. But I found the GPIO pins seems not reset into a rebooted state.
So ESP.restart()'s effect is not the same as pressing the RESET BUTTON.
I'm wondering if there is a quick way to Reset all the GPIO pins into a restarted state by code?

Hi,
I tested the Touch sensor's interrupt function lately.
I'm wondering how to detach the ISR.
How to get access the functions and variables with the prefix "__" in my code?

And how to deInit the Touch sensor, too? Will pinMode(myPin, INPUT) do? I see it be set into ANALOG in the cpp file.
