I've added the buttons and the LEDs to the schematics. I was too tired last night, so I forgot those
. I've changed to code to support both 12 and 16MHz F_CPU clock frequencies. The clock2ne macro has been upgraded to a function. It's a little more robust now.
I've also added MIN_CHANNEL_DUR and MAX_CHANNEL_DUR macros to define the range of duration of a channel in the PPM train. Different TXs have these durations set a little differently, so this can help with that.
I've replaced the attachments in the first post with new versions.
