1. overview

cairotft is a python module used to draw interface on tft screen using the framebuffer interface.

Note

It’s not limited strictly to TftDiplays: stricly it’s limited to framebuffer display (the module could have been called ‘cairofb’ or ‘cairoframebuffer’

cairotft has a strong dependency on cairocffi (https://pythonhosted.org/cairocffi/) and you can use the full cairocffi api in your developments (especially cairocffi.Context and cairocffi.Surface)

for example, to draw a circle, you’ll use fully and only cairocffi methods:

context.set_source_rgba(0, 0, 0, 1)
context.arc(30, 30, 10, 0, 2 * math.pi)

cairotft works on top of cairocffi and provides these things:

• cairocffi to framebuffer interface bindings, mainly hidden for standard use (you only have to paint into your cairo Context)
• double buffering
• widget api and some widget included
• animation framework (for now only very very basic animation bases)
• an async event loop to control all events and display.

More functionnaly will be added later, at this time, cairocffi is at very early stages of developments.
