I see there haven't been any replies to your post yet. Perhaps that is because it is very vague. What sort of example software are you looking for? Which Zilog processor? The Z80, Z8, Super8?

Here's one possibility:

#include int main(void) { puts("Hello world from a Z80 C program!"); return 0; }

There are C compilers that produce code for Zilog processors that will make an executable for this, that will run under a hosted environment, such as the CP/M operating system, or even an embedded system with an appropriate set of stdio functions.

In general, C code is C code is Code, the language is deliberately designed to provide portability between different architectures, and hide, to a certain extent, differences between processors.

Can you be more specific about what sort of C code you are looking for, and which Zilog processor?

Here are some general links:

For the Z80:

Also search Google for "cp/m" for a large amount of Z80 information.

Also check Zilog's web site:

Yes....I know....vague..........hahaha.....I'm looking for C used with the Z8......the dinosaur of Zilog.....

Thanks for your reply, Eric Larson

Z8 the dinosaur of Zilog? wouldn't the Z80 be more qualified for that?

Meindert

Actually, Zilog dinosaurs include the Z800 and Z8000. The Z8 is more like the Alligator of Zilog.. It should have gone extinct 65 million years ago but it somehow lives on..

Did you try this site:

Choose the product: "Jackrabbit (BL1800)". There are some C Dynamic examples. Alex.

I didn't find anything to download if that is what you were thinking......thanks anyway......... Eric

(BL1800)".

You still are not making yourself clear.

Are you looking for:

1. A C compiler for the Z8?

1. C source code that can be compiled with a C compiler that you already have for the Z8?

If the answer is #2, what kind of C source code do you want? What do you want it to do? Control an LCD display? Read a CD and play music?

What???

In your mind you know what it is that you want. But nobody on this newsgroup, or any other newsgroup, can read your mind to find out what it is. If you want help, you have to explain exactly what it is you want. Be specific. Use more words.

I might know exactly where to send you for what you want, but I don't know that because you haven't made it clear what it is that you want.

I would like some examples of how to set up a Z8: ports, registers, and external EEPROM. If the code can show how that is done I would be happy. Speaking of compilers, if you happen to know where I can find one with a debugger, that would be a great help. For now I have a DOS C compiler - only. I'm just interested in being able to set up the Z8 at this point.

This sounds as if you want the start-up runtime source for some distribution. I can't help you, but maybe Jack or someone else can. However your chances for help will be much better if you desist from the annoying top-posting. That means your answer goes after (or interspersed with) the quoted material, after snipping non-germane material.

BTW such source is likely to be mixed C and assembly, or require a specialized C compiler that can accept assembly code.

Have you asked Zilog ? I think this qustion was some legacy-maintenance project, ( hence the OTP Z8 and not FLASH eZ8 ) but the two are very similar.

The new eZ8 tools are likely to be able to also generate code for the Z8, (since that is where they came from ) and there are certainly examples on Zilog's web covering the eZ8, such as this i2c one :

If you want a cheap debugger, then in the best tradition of 'making use of what's available', why not get an eZ8 development kit, and use that as a development vehicle for the older legacy device ? Some conditional compile may be needed, but you also get the ability to launch new designs using the eZ8, plus good training in the 'Z8 gene pool mindset'.

To be even looking at the OTP Z8, you must have some serious legacy momentum, in the form of existing products - which also implies existing code ?.

Zilog do not show 'Migrating Z8 to eZ8' style whitepaper, but you could ask them, or someone here may know just what is the same/different at the lowest binary and tools levels.

Hi, Surprisingly, I got very little real support from Zilog. They were more interested in trying to sell me on a newer chip. You're right, it is a legacy product. The current code is written in assembly and the company wants to update it to C so they can "stich-in" code for a bus they are using with their other products. Anyway, this is a small project to "get my feet wet" and I have been looking examples that I might learn from...I also spent some time trying to locate a IDE/C compiler that didn't cost a fortune. When you compare some of the IDE prices to what Zilog is selling for $50 it leaves you with the feeling that you are being taken......so $1,200 dollars later we have the IDE. I think Zilog would have told me that the eZ8 compiler/emulator would have work....at least one would hope. I guess I should start looking at later chip source for examples...thanks for your reply....Eric Larson

Have you failed to notice that every answer you received has quietly repaired your rude top-posting. Why do you persist in it, especially when given an explanation?
