Error: invalid rotary encoder pin state

Hello!

First of all, thank you for your example!

I get the following errors in the serial monitor:
Error: invalid rotary encoder pin state - prev=0,0 new=0,1

However, navigating through the menu works. Any idea why this happens?
I use the KY040 Rotary Encoder (https://www.ebay.co.uk/itm/274296632950).
Thanks in advance for any tip and help! :-)

Take care...

Change value Slow or Fast

Hello,
first of all, I would like to say that this Menu with Encoder is very good and thank you for sharing it.
I am some kind of beginner in c++. That is why I come here to ask for help.

I think it would be nice to have the possibility to change the values in the Submenu depending on the speed that the encoder is turning.

What I mean is. If turning the encoder slow it would encrease or decrease the value by 1. If turning fast it would change the value by 10 for example.

I would make the following change in the code as follow.

"
// demonstration enter a value
void value1() {
  resetMenu();                        
  menuMode = value;                    
  oledMenu.menuTitle = "demo_value";     
  oledMenu.mValueLow = 0;               
  oledMenu.mValueHigh = 100;        
If (slow_fast== 0) {     
  oledMenu.mValueStep = 1;            
}  
  If (slow_fast== 1) {     
  oledMenu.mValueStep = 10;            
}  
  oledMenu.mValueEntered = 50;           
}
"
Only I don't know, where and how I could change inside the code the variable slow_fast from state 1 or 0.

I would appreciate your point of view and thanks in advance for some help.

display live data

hi, great work there mate,
I have a question, how do you display live data calculated from analog pins in one of the menus?

OLED display simple none blocking menu System on esp8266/esp32 - i2c version SSD1306 - 30mar22

I was searcing a menu code for my project and found this interesting for me. Tried compile with arduino ide 1.8.11, for ESP32 DevModule, but got error message:
enumeration value 'off' not handled in switch [-Werror=switch]

What is the problem?

Problem Uploading

I'm using an Arduino Pro Mini. The SDA and SCL pins are still A5 and A4. However I get this same error when I try to upload to an Uno so I don't think it is a board issue. This code looks awesome and I want to try it but I am having this issue:

It doesn't like this line of code: " Wire.begin(I2C_SDA,I2C_SCL); "

It highlights it when I try to upload it and gives me the following error info

Some idea with a state version of a Rotary Encoder

Hi Alan,

searching for a good and easy to use menu system I found yours and I'm quite enthusiastic on it.
I'm a total greenhorn on all this coding in C++ - so please excuse my poor knowledge on it.

I recently bought an Arduino Uno R4 and I'm fine with it. Now I'm putting together some code to run a menu using this Uno R4, an OLED 128x64 and a Rotary Encoder KY-040 using the u8g2 library.
For the encoder I found a "state version of reading a KY-040, It offers full accuracy unlike other solutions" published by ownprox.

Source is: GitHub - ownprox/Rotary_Encoder_KY-040_Fixed: This is a state version of reading a KY-040 for Arduino, It offers full accuracy unlike other solutions.

Maybe you can include in your project a version which is running with that environment.
For me personnally it would be great if you could provide some advice.

Kind regards
Karl
