I'm writing a little plotting library for LCDs. I'll try to publish it once it's more polished. What do you think?
For now it supports reading data from a Vector, arbitrary scaling on both axes, linear interpolation, different point styles (square, circle), arbitrary many graphs.
I would love one of these with a graph over a period of weeks visible on the screen that gives me soil readings from my houseplant.
Yes, great idea! I love having lil devices around that I can simply look at instead of needing to use my phone or a laptop.
