To connect parallel display to serial port you need some converter for it. Usually they are built of a microcontroller and some MAX232 equivalent to convert signals to RS232 levels. There are several around the web and often they are called "backpacks" or something like that. You can also make your own. Here's one project to make Matrix Orbital compatible serial lcd: http://hyper.sunjapan.com.cn/~hz/PIC/mo-lcd/index.html |
