I thought about it but the 12F683 has only 1 CCP module and so if I wanted to be able to look at R_Common and L_common using that chip I had to do something else.
You only need 1 comparator for both Rcommon and Lcommon, because both signals are synced. (put one on each channel of your scope) R2 and Digital Up are in sync... R1 and Digital Right are in sync.. ect.
BEGIN BTFSS GPIO,RA0 BSF GPIO,RA1 BTFSC GPIO,RA0 BCF GPIO,RA1 GOTO BEGIN
So this CAN be done, lol.
and what do you guys think of this oscope? its a clone of seeedstudios opensource one and looks good enough for anything id need http://cgi.ebay.co.uk/ARM-DSO-Nano-Pocket-Sized-Digital-Oscilloscope-2-8-/300458819103?pt=Radio_Control_Parts_Accessories#shId
I got another one for you... you dont need to use an ADC to see the state of the buttons, it can be done digitally. All you need ADC for is identifying the beginning of the wave train from there you can tell if buttons are pressed or not digitally.
also just curious what voltage does r2 go to when pressed? and then when unpressed?
ur a funny guy :P One of our members Exofire was the first (to my knowledge) to have an Rcommon only RF on the market... and another great looking guy around here also has succeeded as well .
