FastLED interrupt is hanging on esp32 #70

Open iamJoeTaylor opened 1 year ago

iamJoeTaylor commented 1 year ago

Describe the bug I had the same issue on a TinyPico and a Feather esp32. Calling pix.begin causes a failure in the FastLED.show method because Pixie Chroma is calling noInterrupts. FastLED is waiting for interrupts to fire but the interrupts have been disabled causing it to hang and fail with watchdog.

I had this code working in April of last year, but trying to flash it recently caused this issue. If I comment out the noInterrupts and interrupts calls in Pixie Chroma lib it is able to print to the LED screens.

To Reproduce Steps to reproduce the behavior (using the Getting Started)

  1. pix.begin( DATA_PIN, PIXIES_X, PIXIES_Y ); with an esp32.
  2. Build and upload with platform io
  3. See error:

(Note: this error is from my espHome module but the same error and trace happens from a fresh arduino platform io build as well)

Expected behavior Begin should no panic at Watchdog causing any programs to fail.

I can confirm; I see the same problem with both a regular ESP32 and an ESP32-S2. Removing the interrupt lockout solves the issue for me as well. It must be something that changed between versions of the Arduino Core/ESP-IDF since FastLED hadn't changed.

romkey commented 1 year ago

This problem happens with both PlatformIO and Arduino IDE.

Arduino framework 2.0.4 is the last version that doesn't crash this way. More recent versions do. Not sure what the change was that brings out the problem.

@connornishijima do you remember why you were disabling interrupts for this section of code?
