If you go to interrupts, you will not need any pulsin, or pulsout. There are a couple ways to input multiple channels for pulse width measurement. You could either make an interrupt on change on GPIO port, then poll the pins for change, or ....Originally Posted by Acetronics
tie both outputs of the receiver together, and connect them to the CPP1 pin. Only one will pulse at a time (on most rc receivers), so you will be able to read one at a time, even though they are connected together.
One thing I am not sure about is if there is enough time between pulses to read adjacent channels. Have not tried that yet. But channels that are separated by one channel, like 1 and 3, etc would be easy. Hard part would be telling channels from each other. For this, you could place an input on one of the in between channels to mark which pulse width you would be measuring next.
Or, make a multiplexing switch that switches between the throttle, and the on/off switch, and have those go to the same CCP1 pin.
