The library of firmware is very good for basic operations, but is by no means comprehensive. In other MCU environments you can get access to an include file that defines memory locations of all of the processors registers and bitfields and the like. However, in the online world of Particle, where do you find this sort of thing? Can someone help me find documentation or how you find a include file?
In this particular case I’d like to get access to the timer registers so I can do some timing measurements on incoming signals.
