Need help with building/controlling ESC

[dvsvkimo]

Hi, all

This is my first time attempting to create an ESC from scratch. I have read through Microchip's app notes on how to build ESC for brushless motors. However, instead of building an ESC from scratch, I am also thinking if there is any possible way to just feed in signals into existing commercial ESC modules. It will be an excellent alternative if there is any document or manual that can help me on how these commercial ESCs are controlled by the raio recievers. I have a GWS ICS100 chip with me. But if general commercial ESC are controlled in similar ways, I may just refer to any document for help. Your helps are greatly appreciated!

IMO buidling an ESC from scratch is almost imossible for a beginner. It will take many months or even years. It will cost you 10x more than commercial units.

Regular ESC are cheap and controlled by simple 1ms-2ms pulse. This can be done with 10 lines of code in PIC, AVR, or PC. If you are afraid of computers the old fashioned 555 timer chip can be used but needs more components.

There are hundreds of posts explaining how to do this. Here's an example that only uses one part:

Hey, thanks for the replies guys. I am about to try out some PIC programming on my ESC circuit after reading so many application notes and stuff. However I am open to suggestions and any hints and advices are appreciated. :)
