Pulsing switch
Archiver
Posts: 46,084
Hi there! I'm working on a nice menu by LCD driven process. For this
process I have a very nice switch!!! It's a rotating pulsing switch
with a push button in one. This is very nice for menu up/down
(rotating left or right)and pushing for enter.
The only problem is to find a way to decode the pulses.
Pushing is no problem just on when you push.
The problem is the rotating. There are two channels. When you turn
clockwise, the left chanel comes up first, then a very short time
later the second channel comes up. When your going further the first
chanel goes out first then the second chanel. When your turning
counterclockwise the chanels react the opposite way. How do I decode
this. I want to scroll trough my menu with these pulses!!!!
Can anyone help me??? I don't know if this problem is solved before??
Thanks anyway!!!!!

I'm out in the garage making a bracket for one of the Grayhill rotary
encoders as we speak.
