8051 system development from scratch

Hi,

I wan to develop a system with the 8051 Micro controller. I have used a development KIT in college days. In the Kit, it was mearly entering Op-codes and running the program. so, I am not aware of the system the Kit had.

Now, i want to buy a 8051 and other required chips and i want to make a system.

Can you people guide us, how to proceed. and how can i donwnload the File in to 8051. Ie., i need to donwload the program right? and how can i run ?

Before that, do i need to try with some simultors?

Thanks in advance.

Regards, Muthu

I find the Cygnal

kits easy to use. Of course I have the Keil compiler package which interfaces nicely to it so I can't comment on the software supplied with the Cygnal kits. These 8051's have JTAG debug so you don't need a simulator or a separate ICE.

The cygnal chips are single chip processors. That means the Flash ROM, RAM, and all I/O ports are on a single chip. Except for an external crystal, no other parts are needed.

Does the OP want a multi-chip solution or a single chip solution ??

PS: the cygnal development kits comes with a copy of Keil on its included CD. Although the compiler is only good for 4K of code. It may be more that you need on the smaller cygnal parts.

There are kits from Cygnal and Keil. The cygnal is mentioned elsewhere in this thread. The Keil kit is based on the Philips LCP900 range and is about 70USD. Like the Cygnal it too comes with a Keil C51 compiler/Simulator and monitor SW.

There are also any number of 8051 kits about.

As for downloading to the 8051, Philips (see Keil kit) , Cygnal, Atmel, also some good kits, all have flash and the flash programmers are all down load able (free) from the web sites and are inthe kits.

Hi, it all depends on what you intend to make and what you have allready got. Post some details if you want more useful help.

The Philips 89C52RD+ has built in flash boot rom, and there's a free download of Flash Magic to program it. You'll need an RS232 buffer to connect up, of course, and then hang whatever you want to play with on the IO ports.

To write the program, you'll need an assembler (plenty free out there) or a compiler: SDCC is free, Dunfield is cheap, quirky but OK, Raisonance and Keil have a limited free version, both full versions are good but expensive. (Great if you have a project that will pay for them). There are a few others in the same price bracket.

I wouldn't bother. You don't need much hardware to run the processor, I've run them on a matrix plug-in breadboard quite happily. The real difficulty is in the peripherals, and setting up the simulator is in my experience harder than trying the real thing and bashing away until it does what you want.
