I'm using the ppmoutput example. I'm able to vary the position of 4 of the channels using pots. Changing the number of channels and increasing/decreasing the gpins array results in a sqaure wave ouput instead of the previous PPM. I'm also noticing a varying pause between sets of signals, which is only visible using 4 channels.
From the source files I can't see what else has to be changed. I have tried adjusting the pulse and pause lengths with no success, I've also varied the mapping function to map the signals i found in a spektrum radio.

Hi Haroun,
Simply changing the CHANNELS define and the initialization of g_pins should work fine.
#define CHANNELS 2 uint8_t g_pins[CHANNELS] = {A0, A1}; // Input pinsor
#define CHANNELS 6 uint8_t g_pins[CHANNELS] = {A0, A1, A2, A3, A4, A5}; // Input pinshas worked without problems in the past. Could you paste the code you're using here?
