Enivronment Setup Notes:
- So far only tested with the Positive Grid Spark 40 Amp
- Pi version has so far only tested to run on the latest Raspberry Pi OS 32-bit lite image on Pi Zero W and Pi 4B (https://www.raspberrypi.org/documentation/installation/installing-images/README.md).
- Raspberry Pi OS Lite Setup: https://github.com/jrnelson90/tinderboxpedal/wiki/Raspberry-Pi-OS-Lite-Setup
- ESP32 version has so far only been tested in Arduino IDE with the MELIFE Dev Board (https://www.amazon.com/gp/product/B07Q576VWZ). Please check your specific ESP32 dev board pinouts if attempting to use this version.
- Full ESP32 Arduino-Core Setup coming soon!
On client, edit tinderbox.py or tinderbox.ino to match your GPIO mapping or OLED screen type before running.
On demo server (to run on another Pi if you don't have a Spark yet), edit demoLedServer.py to match your LED GPIO mapping before running.
Basic Schematic:
Wiring is more or less the same for the ESP32 version, except in this code pins 4, 5, 18, and 19 are used for button input. Your ESP32 dev board's GPIO is likely different, so please double-check after wiring and before running!
