NHD-2.23-12832UCB3 C Library
Is there a C library available for this component that has an ASCII set-up and at least a demonstration of the graphics? All of the libraries I've found on line have a lot of stuff missing out of them. I have a parallel interface.

I'm sorry, but unfortunately we do not have any libraries available for the display. All we have in terms of code is the example code in the datasheet, and also on our website, here: https://newhavendisplay.com/content/app_notes/OLED_2_23_12832.txt

I have written most of the code but am missing the font tables. Are there font tables available? That seems like the most time consuming and the thing that would give people more problems. I would hate to have to sit around here and write 100 different characters on graph paper and then convert that to a font table.

We have one font table available you can use, I have included it below:
unsigned char Ascii_1[97][5]={ // Refer to "Times New Roman" Font Database...

};If you need other fonts/sizes, you can find many different existing options on the internet, including programs that even generate the bitmaps for you. :)

Thank you for that component library.
Do you also have the waveforms for the 8080 interface? They aren't in the document for the SSD1305 or the Newhaven part. I appear to be freezing up since the transmissions aren't completing correctly.0 -
The 8080 timing diagrams are on page 61 of that SSD1305 datasheet.
