microchip lcd display free sample

I looked at a few libraries (Arduino ones) to get inspiration. In LCD_I2C_PCF8574.c I have added a lot of background and links to where you can get hold of other source, documentation and data on the PIC18F2685, I2C, the LCD and IO expander should you be so inclined. I also added a link to the library I ripped for the character generation. Thanks Mario. This file also contains details on how you may want to customise to your implementation, these are tagged with "TODO adapt" so you can use the MPLABX task list to grab them.

I took all my details/nomenclature etc. from an Hitachi hard copy LCD manual (yes hard copy, real paper an"all!) I obtained in the early 1980"s when we were still printing on flattened trees.

The code in main.c exercises all the functionality of the display including reading DD and CG ram and the busy flag. It should give a good heads up on how to use the library. I included a link to a YouTube Video so you can see it"s potential.

An import function allows additionally to use Windows fonts. With the FontEditor it is easy to generate for example Cyrillic, Greek and Arabic fonts. The preview function shows immediately the size and style in simulation window. When the testboard EA 9780-2USB is connected to the USB port, you can see the character (or any predefined text) live on the display which is plugged-in!
