The development version of Urwid now has support for display and input on a Crystalfontz 635 LCD panel. These are small LCD screens that fit in a PC's 5ΒΌ" drive bay. They have six buttons, four red/green LEDs and a 20x4 character display with an adjustable backlight.
This sort of device is great for simple interfaces to headless machines, like media
PCs and special-purpose systems. Urwid simplifies building an interface
by taking care of text wrapping, scrolling and cursor movement. The new
lcd_display.py module also handles CRCs, acknowledgements and can simulate
key repeating so the device acts more like a regular keyboard. It should also be
easy to add support for other similar devices.
The new example program lcd_cf635.py
demonstrates the new display module and all of
the features of this device. It also provides a good example of how to build simple
menus and customize widgets for a device like this.
