GLCD video emulator
4. December 2008 - 23:34 — admin
A GLCD emulator - takes commands for common GLCD and places output to the TV.
I've found this interesting circuit on the MicroPIC pages, unfortunatelly in Spanish. But the principle is clear and Google Translator helps...
The whole circuit is based on a PIC 18F452 running at 10MHz. No additional ICs are needed, just a bunch of resistors. Schematics and source code are available after registration.
