: Hi All: : I'm trying to write to an LED Display Board. It has four rows, each about 7 LEDs high and can display about 40 characters each about 5 wide per row. Not too sure though.: : Currently it's being controlled by some old software that's not too bad. But I want to improve on it.: : I imagine the board has some driver interface so that when you write to the serial port you send an instruction to the driver telling it to set the state of the LED at a specific location.: : Does anyone have any ideas/suggestions?: : Please help

i also have a project that similar to you. i have to write a program to control an electronic messager. (like the one that show stock market) but i'm still a student in Computer Enginering couse. still lerning. so i do not have any experiance about those project. can somebody give me an idea about how to do that?

from my reading through the web, i descover a device must have driver to be able to comminicate with PC. but for this electronic messager it not even has a driver. is that mean i have to make such a driver??

but i do have the protocol for message passing. i just dont no how to use it. please help me
