Have an error ISR not in IRAM

Question

Hello I had the color weather station working but needed to change the weather ID. I did that and now when I upload I get the "connecting to WiFi" then it says connected and basically keeps rebooting.

when I check the serial monitor it shows this error:

Connecting to WiFi mywifi/mypassword

..........Connected...Initializing touch screen...

ISR not in IRAM!

Abort called

I do have the WEMOS D1 mini pro selected and changed to the 15(16Mil) spiffs setting however I noticed (didnt matter originally as it worked lol) 

that I dont have ....Tools== > ==Flash Mode== select "DIO"

Any Ideas?

Thanks ,Jim

worked perfectly going back to proper version

Answer 1

https://docs.thingpulse.com/guides/wifi-color-display-kit/#install-the-esp8266-toolchain says to install ESP8266 Arduino core 2.4.2. What you seem to have installed is >=2.5.1.

The issue you are seeing is https://github.com/PaulStoffregen/XPT2046_Touchscreen/issues/25 in the display library we are using.

Also ich habe das gleiche Problem. Ich habe das Board Wemos D1 mini pro über den Boardmanager mit Version 2.5.2 installiert. Kompilieren und Hochlade funktioniert fehlerfrei. Nach dem Start des Sketch erhalte ich im seriellen monitor auch:

................Connected...Initializing touch screen...

Ich habe gerade gesehen, dass ich im Boardmanager die core 2.5.2 für esp8266 installiert habe.
Nun habe ich die Version 2.4.2 installiert und im seriell monitor erscheint:

Leider sehe ich auf dem ILI9341 TFT nicht die Wetterdaten. Woran könnte dieses liegen?

Answer 2

I solved this problem using ESP-Core 2.5.2 by modifying the XPT2046 library as follows.

Edit file "libraries/\XPT2046_Touchscreen\\XPT2046_Touchscreen.cpp" in your Arduino libraries folder.

Beginning from line 46, patch this section by adding "ICACHE_RAM_ATTR" at line 49.

#ifdef ESP32
void IRAM_ATTR isrPin( void )
#else
ICACHE_RAM_ATTR void isrPin( void )
#endif

On Github Paul already updated this library but it hasn't been published into Arduino library manager (still version 1.3).

I will try that ...Greatly appreciated, Still trying to get it to sleep and then wake on touch screen..LoL

The new compiler version now checks that an interrupt service routine is located in IRAM, if not as you've seen it gives the warning.

The code needs to be updated to enable the macro to locate the ISR correctly in the IRAM and ad the functions to lock the variables and prevent corruption during an ISR.
