Improved Large Font for LCD
The old implementation of large fonts relied on 7 custom characters (there was a bug in the serial LCD so only 7 out of 8 custom characters could be created). The current implementation with the “standard” LCD allows the creation of 8 custom characters. Together with the built in characters for blank (or space) and completely filled characters, I was able to improve the appearance of the 3-line large LCD font. Here is a simulated display showing before and after. I’ll add large numbers to the next version of the code.
