Project:Arduino Rotary Encoder Menu System
I have recovered a number of ALPS rotary encoders from discarded industrial CRT monitors. I'm working on building a user interface menu system that makes use of the rotary encoders as the sole input technique.
See if it can cope with two encoders at rapid rate usage.
OK, working well --Michael Erskine 18:10, 29 July 2012 (EST)
Raspberry Pi menu for rotary encoder
When using the Raspberry Pi as the menu display system we need to do a few things to a stock raspbian install...
- auto login and start X: use option in raspi-config
- switch off screen blanking: /etc/lightdm/lightdm.conf in SeatDefaults section "xserver-command=X -s 0 -dpms"
- auto start application
Here I'm building a Perl Tk menu application prototype using Tk::Canvas. I haven't yet wired up the serial as I'm just trying out some graphic styles on the small PAL LCD screen.
OK, using adaencoder on the Pi-arduino bridge! The Arduino is just saying what it sees over serial.
