thank for your code it would be great if you share include files also as zip file

regards
Fragrance
 
i think newbie can learn lots from these exampls great work keep it up
 
Thanks for sharing but the given file is just a block diagram. Please upload the schematic, block diagram, and the code with hex file in a zif or rar file which will be highly beneficial to many. Also mention some details about the keyboard as what keyboard is used and how to connect it. Cheers
 
hello.. good day!
is it right to use MCU ATMEL ATMEGA8 in our project "electronic message board via sms"?... we are planning to use gsm module in our circuit...

yes..Mega 8 should work well. The said task can too be done with 89S52 or any PIC micros. Its all up to your knowledge.
Cheers

MOD: I have deleted the video link as i strongly guess you are just here to advertising your products through Youtube videos. As you can see numerous members have posted the need for a schematic of your 16 x 96 Display project which is not yet posted. If you like to share, share it in the right way. Thus your next post will be the schematic or a warning for any video link. We usually kick out spammers.

i'm now working in AVR for led scrolling.
what is in the some header files that u added the program?
"font16x16.h"
"font5x7.h"
"twi.h"
"ds1307.h"
"seeprom.h"
"animasi.h"
"ps2kbd.c"
"uart.h"
"menu.h"
 

I am a hobbyist of Electronics & Microcontroller want to make LED Moving/Static 7 x 80 Sign using 89s52 & 74HC595 my hardware is completed but for the software I want some help from expert.

Is there any one expert? who can help me to complete it.
