Rotary Encoder with ESP-32

I was expecting the same with the ESP-32.  Any advice would be appreciated!

I came unstuck about 30 years go in this way but it was using a 1MHz 6809 - interrupt on one phase and up/down off the other. It did work "most of the time" but if the encode got a jolt, it exceeded the ability of the 6809 to cope. The solution back then was a neat CMOS dedicated  encoder chip.

Even with the grunt of the 32, It does have a huge amount going on so I'd worry if the encode was monitoring a motor.

Thought: the Pi Pico could be a winner peripheral with it's dedicated input handles.

In Bill's latest email, he states "At one point, the remote control even had a rotary encoder on it. I learned the hard way that using a rotary encoder with an ESP32 isn’t as straightforward as you might think. More time lost!"

Can anyone expand on that?  I have a project that uses a few Arduinos and I'm consolidating it into a single ESP-32.  It will be a lot smaller and more powerful.  But I'm currently using a rotary encoder with the Arduino solution.  And it was very easy to incorporate.  I was expecting the same with the ESP-32.  Any advice would be appreciated!

 

Hi Bill, any insights?

I've just got several ESP32's for my next (future) project and was going to ask questions later, however as the subject has been broached I may as well start asking now.

Was the issue interference from the motor causing problems or were there associated issues?

I noted from the link posted by Bill that the TTGO board comes with a display and an encoder.  Does this mean that board cannot be used for motor control.

As a side note my boards C3's were on Dev4 PCB's and require 2 standard breadboards side by side to fit on for experimentation.

I looked it up and the only member using bill as a handle has never posted nor replied. I'm thinking that the Bill referenced above should really be addressed to @dronebot-workshop. That's the Bill that creates the content.

@will 

Thanks Will, that would explain why my past posts have gone unanswered!

I hope you get the information you need.
