As flight controllers become more sophisticated, they have more and more modes. Users of these devices need a way to select an appropriate mode on their transmitters. While the 6 position pot on S3 is a huge step in the right direction, it could be taken a step further. The 6 pos pot is great but its a bit fiddly, especially when using goggles and its only 6 positions. What happens when the next generation of flight controllers offers 8 different flight modes ?
I have an idea to address this issue - edge event switching, as opposed to position switching as the transmitter uses now.
Lets say we used a 3 position momentary contact switch wired like this for S3.
If one could capture the event of the user briefly moving the switch to one of the positions, we could increment or decrement a global variable. One could then define a mix based on the value of that global variable. Lets call our global variable FlightMode. Flightmode could hold values of 1 through 8 for 8 different flight modes. Using the switch, the user could toggle through each mode in an up and down fashion.
I feel a switch like this would be much less fiddly than a 6 pos pot.
This switch could also be used for things that work with discrete settings: fligth modes, flap positions, etc.
I've obviously ignored things like overflowing or wrap around on the GV as well as debouncing the switch. I'm sure there are other details that will pop up when actually implementing this.
Is it possible to implement an edge event on the S3 input ? Is it practical to do so ?
I've done some embedded C development if someone will show me the path to implement this ???
