TFT-displays

Details

The TFT-displays are intended to be used with the AdvaBoard RPi1. They can either be directly stacked on top of the AdvaBoard, or connected with a 40 pin ribbon cable. No additional cables are neccessary.

All displays contain 4 mounting holes, which can be used to connect the display to a front panel or the the AdvaBoard RPi1. The mounting holes of the 3.2"-TFT-display are exactly at the same positions as the ones of the AdvaBoard RPi1, so the 3.2"-display can directly be fixed to the AdvaBoard (with some spacers).

All displays have a resistive touchscreen and an adjustable backlight.

Software

The following software is available for the TFT-displays (in connection with the AdvaBoard RPi1):

• framebuffer-driver for Linux (to use the display as standard Linux-display incl. X11)
• touchscreen-driver for Linux
• C- and Python-library to directly access the displays

So, the displays can either be used as normal Linux-displays, or used directly by C or Python.
