8x8 Scrolling LED display (Simple example)

[baco1978]

Hi,

i really like the idea of a scrolling temperature display.

could somebody post the hexfile?
in the lite version the 16F872 isn't supported

thanks

dear wellyboot,

thanks a lot for share this application with the members..
can u modify it to a scrolling clock or both scrolling clock+thermometer??
i really need one to built...
waiting for ur reply

thanks

Now that i see the circuit again, why not use the 2803 instead of two 2004?

hi

the only reason i used 2004's is due to me having loads of these floating around, when i bought them i wasnt aware of a 8 channel device.

cant see any reason you cant use a 2803

I would connect to a DS1307 Real time clock IC, add a couple of buttons then you could modifiy the code to read/write to the DS1307 and convert the digits to be displayed.

search around for examples of how to read/write to the DS1307, then the rest should be quite easy.

Dera sir,
first of all thanks for ur reply..
i'm just a beginner for these field...
i did all hardware for ur scrool temp display..but when i try to convert
(by using MPLAB ide 7.5) ur codes to hex file,i give the path to saved it in C:\out put directory in my pc..

these errors came..what mistake did i do..?pls help
thanks

Dear
wellyboot

i think the program me is not compatible to mplab..

can u give the programme language name n a compiler to convert ur codes to HEX format..?

if u post hex file il highly appreciate.

i buld all the hardware but stuck in software part that unable to finish..

hop u can understand my situation

thanks
