Hi all,
This is more of a can-it-be-done than anything else.
At present, I've a circuit that generates two pwm signals (one carrier, one signal) and combines them via an external transistor.
Is there a method I could use to combine the signal internally before sending it to the output pin? I know I could do it with just the picaxe bh taking the output pins, reading them in on another pair of pins and outputting that, but that needs 3 extra pins and I'm trying to reduce the component count if possible
