A large part in ensuring our payload works as intended, is to test either parts of, or the entirety of any drivers we write. Often times, this includes wiring the subsystem together, and signal testing the output using an oscilloscope. As such, this document is going to over the basics of how to get started in camera driver testing with the RM46.
It is imperative to understand return types for the functions you are testing, as you will need it to understand what you see on the oscilloscope, as well as to make sure that the oscilloscope either validates or contradicts your required function output.
