I added the Music Maker FeatherWing to a ESP32 Feather V2 device and I’m following the instructions in the tutorial to run the feather_player sample sketch. I put some music files on the memory card, inserted it in the memory card holder then changed the file names in the sketch so it plays the sound files I have on the memory card.
After sorting out how to deploy code to an ESP32 device that runs different code on each processor core, I set about building out my application. As soon as I added my project's code to one of the cores, the device started rebooting again when it ran the code and generated the following error message:
I built several projects on the ESP32 platform over the last few years; I recently published an update to my Glowing Pumpkin project. The project basically randomly flashes some LEDs with the intention that you put it inside a carved pumpkin and it does cool light effects inside the pumpkin. I wanted to build a version that used web application to control which color displays on the device so I set about learning how to run two processes on the processor, one that handles the LED stuff and the other that runs a web server accepting color requests from a remote device like a smartphone or tabled.
