Maybe you should post a link to your development board and exact processor used. There are so many different ways to connect displays. -simple 8-bit bus + couple control lines parallel lcd to cpu GPIO pins -similar parallel lcd to cpu external bus (if yours has one) -SPI and other serial bus displays -controller chip to cpu external bus + controllerless display (this is usually what needs to be done with larger displays) -or if you're lucky your cpu already includes a lcd controller -etc Maybe the simplest way to go would be to connect a relatively small display to the GPIO pins. How large resolution should your display have ? |
