Hello.I build the project as indicated by : T.Jackson , Luciano and Magu etc.I did all the tests indicated in the previos threads and I think it will work with just a litlle help that I will ask from anyone...The problem is : when I start it all the LEDs flash with no sense , when I put the board in program mode the led stays on after it blinks for three or four times but the software tells me that the port is not found or is it in use but it isn't so.I belive that if I solve that problem I will finish the board.I dit test the software on win 98 and xp.Mayby if i can find an image of an 24lc256 that works i can burn on my eeprom and see what happens.Thanks a million times.

A little bit greedy aren't ya? It's only been six hours.

If you read the thread (yes all one million posts), you'll see that while the initial posting of the project had an error or two, all issues were successively solved.
There's even step-by-step troubleshooting in there somewhere.

Thanks.
Like I said in my previous posts : I think my board is ok cause it's made after magu(zamfirelu http://www.zamfirelu.org/dtpt/viewtopic.php?t=254) schematics , and a read over and over again the whole thread...the problem is that I can't connect with the computer to the board and today i saw that even when the eeprom in not present on board , the LED for programing blinks the same like with the eeprom on it.
Again thanks a million.
P.S. : I contacted magu on his forum and i stand in touch with him last year , when i first begun to build the display , but until now he did not respond to my new posts , so that is why I decided to post in this forum that started all...
P.P.S. : I'm impatient to continue the project because in this period I have time to do so.

i had to so some reading about serial eeproms and i am wondering if i can use a 24c16? apart from changing the control code and space limitation comparted to 24lc256, do you think i will have any problem assuming i am able to take care of the issue of pin compatbility if that happens to be the problem, i am really sorry if i am fooling around again with my question.


having to load message means i have to bring down my display and use my desktop serial port, i also bought a programmer and it has serial port. i was thinking if i can use a usb to serial converter so i can use my laptop to both load message and can also use the serial pic programmer with my laptop by using the adaptor. has anyone tried this out?


is there a free software or utility with which i can generate my custom character defintion for any matrix size i want, because i want to actually make a 14 by 10 size matrix display.


i was thinking of using red green and blue led in sequence so that when they scroll i sort of have a colored display, but the current required varies to get some level of brightness for the different color of leds, any advice?

thanks alot
