Example project that shows how to use the espcd-library and how to automatically build and upload the firmware using github actions.
Open espcd-example.ino.
Adjust at least the cert[] variable, the espcd backend url using espcd.setUrl(url) and the product id using espcd.setProductId(id).
The cert variable can be extracted using a webbrowser. Open the backend url (e.g.: https://api.espcd.duckdns.org/), display the certificate chain and select the root ca with the longest validity. Open this PEM certificate and paste the content into the cert variable.
If a product id is specified, the uploaded firmware is automatically associated with that product. This allows the devices using this product to update the firmware automatically.
Open .github/workflows/arduino-compile.yml.
In the matrix, adjust the fqbn's for which the sketch is to be compiled.
In the steps adjust the sketch. (More information here).
Create a new token in the espcd-frontend and add this token as new secret API_KEY in the github repository settings.
