Frequently Asked Questions
First of all, take a look at the examples and the Wiki - especially the Basics page. There's a lot of useful information over there. If something isn't working as expected, try searching the issues.
While RadioLib was originally written with Arduino in mind, it has since evolved and contains its own lightweight hardware abstraction layer. Thanks to this layer, RadioLib can be used on non-Arduino frameworks as well. See this Wiki page for details.
First, check out the Troubleshooting Guide, which sums up the most common issues and how to resolve them. The fastest way to get help is by creating an issue using the appropriate template. It is also highly recommended to try running the examples first - their functionality is tested from time to time and they should work. Finally, RadioLib is still under development, which means that sometimes, backwards-incompatible changes might be introduced. Though these are kept at minimum, sometimes it is unavoidable. You can check the release changelog to find out if there's been such a major change recently.
See this Wiki page - it even has an example for ESP32!
Start by creating new issue (if it doesn't exist yet). If you have some experience with microcontrollers and C/C++ in general, you can try to add the support yourself! Use the template files in /extras/ folder to get started. This is by far the fastest way to implement new modules into RadioLib, since I can't be working on everything all the time. If you don't trust your programming skills enough to have a go at it yourself, don't worry. I will try to implement all requested modules, but it will take me a while.
