These are nice little displays and the data sheet is relativly understandable. They have a selectable interface with I2C, 9bit SPI, 8Bit SPI and parallel.
You usually search the web for the card that offers your comms flavour of the moment.
For me its easier to get them mounted on boards than solder the displays to your own PCB and this is where the problems begin. Not all boards are the same.
The first board I used is nice in that its mounting fabricator made their design toggle the reset line of the display on start up, so as a result, the reset default values get set up in the displays registers. This design is no longer available on the web.
Same display different mounting fabricator and a problem of garbled text and graphics has to be resolved.
Upshot is a complete rework to my software drver and a new software reset routine, that set all the display registers to the defaults that would be set if the hardware reset line had been toggled.
Time 20 hours, well at least my driver should work with most fabricators displays now?
At least your projects make some progress. I have 2 or 3 that remain at the conceptual stage, continually being subverted by other projects like painting the garage doors. My wife insists that I get my Vitamin D quotient, so summer is a blowout even though the only cool place is the basement where coincidentally the projects are executed.
You all seem destined to end up as I have, with a basement full of projects in stages ranging from completed but abandoned by technological obsolescence to still in the conceptual phase (usually including partial schematics, data sheets, and parts all sitting in a shoebox). Some of mine go back to 1960 or so! I did usually manage to complete my projects in the 1950s.... My big advantage is that as I do not undertake any projects that would entail resuscitating my ancient SW skills, most of the projects you are entangled with would never appear on my list!
Yes, I do seem to be headed in that direction along with significant spill over of parts into the garage. Since I've moved a few times, I don't have anything much earlier than about 2000 or so. I have actually finished a few along the way. The problem is that I can come up with projects far faster than I can do them...
My collection has traveled with me from NJ (where I grew up) to Boston, Chicago, Ft. Lauderdale, Atlanta, Dallas, then back to Atlanta. Very little "triage" in all that over 54 years! Ever since I first became a homeowner, having a large basement has always been a priority for me (except in S. Florida and Texas, where they are non-existent or very rare).
@Wnderer: Speaking of projects, what happened to the Van Gogh Mosiac with home made ceramic bits?
Arrgghh -- that's the one project people always ask me about. The frame/base is sitting on the wooden chest outside my office -- I have a bunch of new glazes I want to experiment with -- I really need to fire up the kiln and get back to working on that ... but my weekends are now fully booked until the end of August (I only hope I won the lottery this past weekend -- I forgot to check the tickets -- if I did, I'll be able to devote a lot more time to my projects LOL)

Actually, most of my projects are progressing rather well, although they do tend to move in "fits and starts" -- I think you will be surprised by the progress I have to show in the next couple of months...
