Fine-grained ribbon cable failure on a TI-83 Plus Silver Edition
Replacement 128x64 LCDs: LCD 64128M FC BW-3
Reverse-engineering testbed, with STM32 Bluepill
Soldering 28 wires onto a 64128M FC BW 3 LCD module for testing.
First success in writing to the LCD: a Cemetech logo (displayed from the microcontroller)!
Experimenting with translating LCD data from the calculator to the new LCD. Timing and speed problems abound, although the occasional '5' and 's' are a good sign.
Since the calculator outputs pixels slowly while graphing, I was able to capture this surprisingly correct screenshot.
