AUX1 and 2 for 5 Channel PPM Sum
Posted: Mon Dec 19, 2011 3:04 pm
Hello everyone,
Here is an idea to be implemented:
Instead of using 3 position LOW, MID, HIGH for the 5th channel can be this channel divided in let's say 5 positions.
(2100 - 1100)/5=200
I think 200 difference between the positions are more than enough for very good detection of the switch mode.
Why you will ask, why you need 5 positions, because the most of the radios have 3 position switch. Well the answer could be simple:
Some TX stations are very smart like (Futaba T9CAP or T7 not mentioning the more expensive ones) and can assign many switches to the same channel so actually you can use 2 switches (one with 3 positions and other with 2 positions) to command the 5 step channel with different values.
This will eliminate the need for reading the 6th, 7th and 8th channel with a non PPM sum reading method.
I am the owner of a T9CAP and i managed to modify a TX FS617 to get 5 channel PPM sum out of it but if i need another channel from tx to be read by the arduino, i will have to change the code to actually use PPM SUM plus the default mode with interrupts.
Using 5 step on the 5th channel i can eliminate this problem. (I could also buy FrSky TX and RX with ppm sum output , but think about it: you can have more combinations with less channels.
So what do you think ????
