[QUOTE="Hotwire, post: 83441, member: 505"] FPGA sounds like a very tough choice. You would need to include a minimum of 3 giros. You also need to know the ESC com system which isn't open sauce for DJI and I'm sure they no longer use PWM. If you wish to build a UAV from scratch and FC from a chip, go and check out betaflight or one of its predecessors. There are plenty of small programmable chips that can get you going. Start with a PWM ESCs because most of the code for PWM already exists. Same goes for Rx coms, just start with a big chunky PWM Rx. DJI are very closed shop. You aren't likely to get any help from them. They have been close since the beginning. [/QUOTE]
