Looking for a good starting point on teensy 4


New member
Hi, I'm looking for some recommendations on beginner's guides for using the hardware in a Teensy 4.1. I've used a bunch of libraries and done some other work but I'm curious about how the libs are written and I think it's a good time to learn how this stuff actually works. I especially want to know how to use the internal timers and interrupts but I know I need to learn a lot more.
Does anyone know some good resources, books, tutorials etc. I could read?
Are you interested more in the library creator side or using libraries in a more advanced way?
