You got me thinking on the switches how you done it with a digital pot IC.
I think I know now. I'll give it a shot. Your making the pulse width equal to a digital number. lets say 1 ms = a wait of 0 . pulses = 1ms to 2ms on each channel. .01 ms = switch 1 on .02 ms = switch 2 on .04 ms = switch 3 on .08 ms = switch 4 on .16 ms = switch 5 on .32 ms = switch 6 on .64 ms = switch 7 on so if you had switches 1,3 on then the total pulse would be 1.05 ms if you have switches 2,4,5 is on the the total pulse would be 1.26 ms You get my thoughts . That could give a total of 7 switch in the digital word in 1 ms of width. Is this the way you did the switches on the transmitter. The Rx would need a Pic to detect that pulse width and turn on the outputs for the switches . Charles |

The pulses from the receiver go to the OSD PIC controller. The controller measures the pulse length and canculate the state of the pulses. Frederic |
