Electronic – What’s the difference between AT89S52 and AT89C52

avrmicrocontrollerproteus

I am working on a fingerprint security project, based on what I've read so far, I decided to go for AT89S52 as my microcontroller, but I got stuck when I decided to simulate my circuit on Proteus 7.8.

The software offers me AT89C52, but i didn't see AT89S52. So, I am stuck between using AT89C52 but am scared if is going to affect my work, since I don't know if they are the same.

I thought about using another electronics schematic software, I am willing to change but don't know what else to use besides Proteus and the Keil compiler I'm using now. What to do?

Best Answer

For the purposes of Proteus simulation, the AT89S62 and the AT89C52 are the same.

Presumably you will be simulating run-time functionality, rather than electrical behavior at programming time.

In any case, Proteus cannot simulate the actual in-circuit programming of its microcontroller models, so you're good.

The .map file that's part of the bundle you shared shows that the Microchip C30 compiler was used to build this project. Unfortunately I don't see what version of C30, but at least the compiler is known.

c:/program files/microchip/mplab c30/bin/../lib\libpic30-coff.a(crt1.o)
                          (_resetALT)
c:/program files/microchip/mplab c30/bin/../lib\libpic30-coff.a(crt0.o)
                          (_resetPRI)
Program Memory Usage

There's a free version of C30 (no optimization) that can be downloaded and installed from Microchip's website. Give the latest version a try and see what happens.

Electronic – How to burn hex code program file into AT89S52

Unless the AT89S52 has a bootloader burned into it (unlikely) you will not be able to program it through the serial port.

Your board has an ISP header on it which is used to program the MCU. You need an interface cable and application designed to program Atmel MCUs via ISP, eg. Ponyprog.

If your computer has a parallel printer port then you can use the simple circuit found here:-

If you only have USB then get a USBASP and use AVRdude as described here or ProgISP as described here.
