The touchoffset.py example demonstrates interactive touch handling and rendering using Bridgetek EVE chip. It defines a Subwindow class that displays button groups on separate surfaces, manages touch highlighting, and uses EVE commands to render graphics and handle touch offsets. The main loop alternates between two subwindows, updating the display and tracking touch events, while efficiently managing frame rendering and swap chains. This example is to showcase touch offset and button interaction features on EVE chip.
The format of the command call is as follows:
MPSSE example
python touchoffset.py --connector ft232h
FT4222 example in single mode (--mode 0)
python touchoffset.py --connector ft4222module
FT4222 example in dual mode (--mode 1) or quad mode (--mode 2)
python touchoffset.py --connector ft4222module --mode 2
The example contains a single file which comprises all the demo functionality.
