View Full Version : Using Propeller chip to communicate with R/C transmitter & receiver

05-25-2010, 09:14 AM
I am trying to control the speed of a brushless motor in a R/C plane that is connected to a ESC, but I want to use·a PWM signal from the propeller chip·I/O. How can·I·use the·throttle input from my Futaba 72MHz 6 channels Tx/Rx to control this PWM signal going to the ESC.

Take a look at this obex project http://obex.parallax.com/objects/482/

I posted a program to the OBEX that drives an ESC from a PC keyboard to test out the motor. There are objects in OBEX that can read an RC receiver, and others can drive servos. Basically a servo and an ESC are the same.
Here is a thread that has other code posted, etc http://forums.parallax.com/forums/default.aspx?f=25&p=001&m=436063
