So, I’ve made a decent amount of progress. I’m using a raspberry pi Pico running Micropython for my mpg gauge. I’ve got enough code written for just instant mpg to appear on the screen, and everything should work when I hook it up to my car this weekend. I’ll have to rewrite the frame buffer code for this screen library before I can display any more characters. Using PIO, I can get the frequency and duration of the injector pulse, and also the frequency of the VSS pulse. It’s working on my test bench, just waiting for diodes to arrive.
