The simple.py example demonstrates using a custom font and loading a JPG image in a program. The custom font and the image are loaded to RAM_G and display using font/bitmap handles. The data for the font and the image are stored as python byte arrays and loaded using the coprocessor. The image is in JPG format and is decoded using the CMD_LOADIMAGE command.
The simple2.py example demonstrates that instead of repeatedly sending the entire display list as simple.py example, it uses CMD_COPYLIST, CMD_CALLLIST and a small list that includes only CMD_SWAP to detect REG_TOUCH_TAG value. A full display list is sent again only when a valid REG_TOUCH_TAG value is detected.
The format of the command call is as follows:
MPSSE example:
python simple.py --connector ft232h
FT4222 example in single mode (--mode 0):
python simple.py --connector ft4222module
FT4222 example in dual mode (--mode 1) or quad mode (--mode 2):
python simple.py --connector ft4222module --mode 2
The example contains four files which comprises all the demo functionality.
