Hi, I have been trying my hand at a bit of NQC for the BrickOS firmware recently and working with BricxCC. So far it has been good fun although I was wondering if anyone has any tips for getting LNP to run on my brick. As there is an option in the (...)

Hello! I just started using brickOS and am trying to use it as a programmable function generator. As such, I'm trying to get good repeatability on cycle time.
