Encoder error: "ISR not in IRAM" on Wemos D1 Mini

[aliusc]

Hello,

I trying to set up this library with my hardware. I use Wemos D1 Mini, rotary encoder, 1602 LCD via PCF8574. For ideal test condition I selected LCD > PCF8574 example.

I have wired encoder's CLK and DT to D5, D6, encoders switch to D7. I use ESP8266 core library 2.6.3. Code compiles well and starts up, but frequently reboots with Error in console:

Arduino Menu Library
ISR not in IRAM!

User exception (panic/abort/assert)
Abort called

I have tried to lower core library to 2.5.0, but error was still here.

When I comment out encoder and leave LCD and button only it starts up correctly. I have read interrupt functions should have attribute ICACHE_RAM_ATTR to make them work correctly. But I have difficulties to add them to proper functions. I have tried to add it to "menuIO/encoderIn.h" to functions "encodeInUpdateA" and "encoderInUpdateB" declarations: static void ICACHE_RAM_ATTR encoderInUpdateA(class encoderIn<pinA,pinB> *e); static void ICACHE_RAM_ATTR encoderInUpdateB(class encoderIn<pinA,pinB> *e);

and void ICACHE_RAM_ATTR encoderIn<pinA,pinB>::encoderInUpdateA(class encoderIn<pinA,pinB> *e) function declaration. Sadly it didn't helped. Maybe anybody had similar issue and may suggest where to add "ICACHE_RAM_ATTR" attribute? Thank you

Hi! The builtin encoder uses pin change interrupts and was tested on AVR's only, clickEncoder (an alternative) has been used with esp8266.

One can even use other encode/input method and issue menu commands when appropriate, after reading the input.

codeCtrl example is about menu commands

Saldy clickEncoder did not compiles for my board, but I'm not sad as I found codeCtrl example! It opens all possibilities of menu I need. I can control rotary encoder and button from my code. So i will adopt my project to work with this menu and get rid my old menu code I used as it is bit hardly maintained. Thank you for your support.
