it consist of AT89C51 24PC + 2x16 LCD + 4x4 keypad
program using assembly code...
rili need help how to construct the circuits...
hope sumone can help me here..
thanks!!!!
Im havin : AT89C51 24PC microcontroller, LCD n keypad tat i mentioned from my previous post...
erm.. i dunhav much experience in microcontroller and can say im a beginner...
hopefully i can get some experience from here...
so da 1st problem now is i dunno how to construct da circuits....
i need a "schematic diagram" so i can buy all da components together then i can start work...
hope u can help...
Search the web. I've seen this numerous times for different MCUs, should be hard to find the hardware schematic that suits your needs. Think this is on Nigel's Tutorial site for PICs. He does mostly 'C' if I remember right, so maybe not so tought to port over to AVR. If you are new to MCU, it's a great site, even if it only focus is PIC. It helped me a lot when I was getting started with AVR. I don't use PIC or 'C", and PIC assembly sux...
The hardware part of the project will be pretty much the same regardless of which MCU. The I/O pins work pretty much identical, and that's all you will be using on this project.

connecting lcd, 89c51, keypad and servo motor all together...
but the problem now is in this circuit it is using PIC instead of 89c51...
do u hav any ideas about that? cause in my project really need to use at89c51...

It uses your MCU, explains what and why for the keypad and LCD. Check the other tutorials (all your family of controllers), maybe a servo tutorial. I've got a servo tester circuit for the tiny2313 in assembly. Haven't built it yet, but has an LCD, 4 buttons, controls 2 servos, and can decode the PPM from an R/C reciever, pretty cool.
