Try adding a dummy return value to following function in IS31FL3733.cpp or better yet, make it a void : uint8_t IS31FL3733::set_page(uint8_t page) { write_reg(0xFE, 0xC5); write_reg(0xFD, page); } I had this exact same problem after moving to 2.0.11 ESP32 Arduino. See https://esp32.com/viewtopic.ph...

You can debug the backtrace. https://github.com/espressif/arduino-esp32#decoding-exceptions If you roll back to the version of arduino-esp32 you originally programmed the code in, it is likely to work. You can see the branch dates at https://github.com/espressif/arduino-esp32/releases After several...

I have a question about the operation of ESP32 after uploading code in the Arduino IDE environment. This problem has been bothering me for several weeks. Let me first describe my environment: OS version: Windows 10 Pro 22H2 (19045.3324) Arduino version: 1.8.13 Board Manager ESP32 version: 2.0.13 (by...
