### Device definition method
|
|
|
|
_One firmware to rule them all._ Not really :-) one per device platform (ESP32, ESP32-S2...).
|
|
|
|
There is no need to compile the firmware for your EVSE design.
|
|
Source code ist not hardcoded to GPIOs or other hardware design features.
|
|
All code is written in ESP-IDF without additional mapping layer like Arduino.
|
|
|
|
All configuration is written outside firmware in configuration file named _board.cfg_ on dedicated partition.
|
|
For example, on following scheme is minimal EVSE circuit with ESP32 devkit.
|
|
|
|
|
|
|
|
For this circuit there is _board.cfg_, for more information's see [Wiki](https://github.com/dzurikmiroslav/esp32-evse/wiki/Board-config).
