circuitpython-vfd-gu7000

API for Noritake's itron GU7000 series VFD. This is a partial implementation.

See example.py for actual usage.

Notes

Not all GU7000s have native support for bit paint. As a workaround, I implemented fill_rect and fill_line as generic solutions.
This lib only implements communication through async serial port(aka. UART) because it's relatively easy to implement. It should be easy to implement for other connection types.
For this lib, the major difference between MicroPython and CircuitPython is the serial API. It should be easy to port this lib to MicroPython.
- ~~BTW it's also easy to port the lib to CPython.~~ Already ported, see for_pyserial. You'll need an adapter supports CTS/RTS flow control like CH343(with VCP driver, NOT CDC-ACM driver).
The image convert tool is in for_pyserial/vfd_utils.py. See for_pyserial/show_img.py for usage.
