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.
I'm a huge fan of Adafruit's projects, especially the Feather series of microcontrollers and associated FeatherWings (add-on boards). The format is so popular that Particle (another one of my favorite hardware companies) even adopted the footprint for their latest hardware.
I'm working on a project that uses an ESP32 device with an Ionic Capacitor Electron app. The ESP32 device runs a web server the Electron app talks to and with the latest version of Capacitor Electron, when the app makes an API call to the ESP32 device, it completes successfully, but Electron fires the following error:
