Arduino-PPM-Generator

Sketch for Arduino Nano allows you to generate a PPM signal. It uses a hardware sixteen-bit timer. The pulse duration is adjusted with an accuracy of 0.0625 microseconds.

Modbus registers

#	Mode	Size (bytes)	Description
0	R	2	Clock ticks per 1 microsecond
1	R	2	Maximum channels count
2	RW	2	State 0 - Off / 1 - On / 2 - On inverted
3	RW	2	Channels count
4	RW	2	Pause length in the clock ticks
5,6	RW	4	Synchro pulse length in the clock ticks
7	RW	2	Channel #1 duration in the clock ticks
...	...	...	...
n+7	RW	2	Channel #n duration in the clock ticks
