[Today’s run: Limerock Road, 4 miles]
I’ve been letting my GPSDO measuring go on for about 3 weeks now. And The BeagleBone/weather station thing is running along. So I took a little break and dug out something I have had on the shelf for about 3 years.
I was at a hamfest in Ft. Collins, Colorado, probably 3-4 years ago, and I bought two small LCD panels. They are marked G121CB1P00. Turns out that there is information about these on the internet. I was able to find the datasheet and how to program them. They are pretty old technology and probably not fooling around with very much.
But fooling around is what I do.
So I was looking at them and wondering what it would take to make them go. I really like this BeagleBone thing, being able to write shell scripts or perl scripts to do pin-by-pin I/O. But the BeagleBone uses lower voltage for GPIO operations and this LCD needs 12 lines with 5 volt logic. That would be kind of a pain. I do have some small PIC processors that would do the job. But then I have to figure out how to write a PIC program and get the thing programmed up. I don’t know if I am that ambitious just to see the LCD light up.
