New component: text LCD #405

Closed RREE closed 2 years ago

RREE commented 2 years ago

This patch add simple text based LCDs based on the HD44780 driver. Almost all text LCD use this or a compatible driver module.

This first version uses a PCF8574 I/O expander via I²C. I can also add a 4bit implementation, but that requires 7 or 8 GPIOs of the controller. That's why I don't use it anymore.

As a prerequisite this patch requires the merge of the aforementioned PCF8574 pull request.

I created the branch in my copy of the ADL off the branch for the pcf8574. It seems that this pull request contains both the pcf8574 and the new LCD code
