This hack lets you use a TV in place of a graphic LCD screen. But we like to think of this less as a replacement for a GLCD and more of a simple way to get your information onto a television. A PIC 18F452 acts as a translator between the GLCD parallel inputs and a composite video output. There are some malformed image links on the page which we’ve fixed and linked to after to the break so that you can take a look at the schematic, component layout, and PCB artwork. The assembler code and hex file are available for download but you’ll need to register to get access to them.
