It seems nobody has a simple explanation for inputing R/C. I did Google quite a bit.

Did you run across Larry Barello or Bob Blick's 2-channel to H-Bridge mixers?

 

Barello has a assembler project that describes mixing 2-channel RC input channels into an H-bridge ([url=http://barello.net/Papers/RCtoPWM/index.htm]http://barello.net/Papers/RCtoPWM/index.htm[/url]) and a C/Assembler project that exercises 4 RC channels via a joystick ([url=http://barello.net/Papers/ServoPulseGenerator/index.htm]http://barello.net/Papers/ServoPulseGenerator/index.htm[/url]). He seems to use the AVR microprocessor in C and Assembly, but translation shouldn't bee all that difficult.  As far as resolution of the PWM pulse, Barello seems to achieve 1 microsecond.

 

Blick has a project note for a dual channel PWM to H-Bridge written in C[url=http://www.bobblick.com/techref/projects/sv2hb/sv2hb.html] (http://www.bobblick.com/techref/projects/sv2hb/sv2hb.html[/url]).  

 

In each project, you may have to read both the description and code to get a clear picture of the R/C input.
