Hi folks! I want to make my own simple PIC16F873 based R/C transmitter. I will= include four control channels with some simple functions. However, I need to generate the TX pulse train inside the microcontroller= and use my existing RF module for the radio transmission. There are several FAQ's on Internet which explains the format of this PPM= signal. Do anyone have tips generating this? Timers and interrupts, yes, but how to obtain a good resolution in position= variation? (and what is good variation anyway?) Maybe anyone has hacked the software principles of a computer based R/C= radio?
