Encoder - ESP8266(WEMOS D1) - PWM

SultanRR · February 24, 2025, 10:51pm

I’ve been tormenting the unfortunate code all evening, getting lost in three pines))) Even gpt4 didn’t help me.
The goal is still to study (perhaps in the future I would like to make a reference voltage regulator for TL494 and there are many other ideas, but for this you need to adjust the borehole) but first, I want to figure out how to smoothly adjust the borehole of the PWM signal with a given current frequency using the encoder: one click clockwise +1% fill, and -1% counterclockwise rotation . While some nonsense is being obtained , when rotating in both directions , only a decrease in filling occurs, if you turn sharply clockwise, it can only start to increase %, regardless of which way to rotate , until you turn the encoder sharply again , which can switch the direction of adjustment Here is my code and a little bit of logs :

Clarification arrived :
The encoder needs to go to 0, that is : in the logs ([02:39:57][D][sensor:093]: ‘Rotary Encoder’: Sending state 0.00000 steps with 0 decimals of accuracy ) I make one hundred clicks of the encoder clockwise and 100% filling is set, then I make 100 clicks counterclockwise and only at 101 clicks the purity begins to decrease and only at 200 clicks counterclockwise the filling will be 0 . And let’s say I take 200 more steps counterclockwise, then I will need to take 301 steps clockwise to start increasing the filling again, and then there will only be 1%,302 steps 2%, 400 steps 100% …

Instead of the lambda you have for trying to count depending on direction turned, why don’t you calculate those values using on_clockwise: and on_anticlockwise:? Then it doesn’t matter if you are at zero to start.

I have just solved the problem, while everything is working I will test it)))
I needed to track not the value of the encoder steps, but the increment or decrease of successive values during rotation)))
