From: Lodewicus Maas on 20 Sep 2009 14:19 In the country I'm living - PIC's are really hard-to-get ,and at a price. I started looking at Ebay and found the cheapest option available which can give me 32 I/O ports, and the best offers I could get was on the AT89S52, and this is how I ended up with the ATMEL product I definately agree with a few posts that PIC might be easier and maybe cheaper, but like I said, I had to look at availability/price first, and now I must move on to the next step, which is compiling the code I already written over the past 2 months - without having any compiler or hardware. My programmer arrived on Friday and as soon as I made up my mind on a compiler, then I can test(compile) the code which is currently only in a ..txt file, and hope there is no compilation errors. My AT89S52's should arrive within the next 2 weeks, and only then will I see if the past 3 months was a total waste of time. Thank you for all the input Much Appreciated Lodewicus Maas

The AT89 is a fine chip for some uses. I'm not sure why you haven't tried to compile the code, though. As Chris has mentioned, there are demo versions of commercial c compilers that are available. And besides that, there is SDCC which you could also do some trial compilations with. I'm not sure if the Keil IDE can do this (it may work, just fine) but Silicon Labs has an IDE as well for their 8051 core cpus and their IDE (and SiLab's web site discusses this in an appnote) can integrate SDCC into it, so you should be able to run some tests that way. There are some slight differences in syntax for ports, if I recall, but that's also documented. At least you could have tested for compilation before receiving parts. I am gathering now this may be a hobby project, though you still haven't said. Best of luck, either way. Jon

Still, I'm sure you meant this last part in a positive way so I'll just say you shouldn't worry. Just met with my Representative over lunch, a few days ago, for example. Plenty on my plate in that regard. No pun intended. Jon P.S. I'd still think it would be helpful to others if you'd expand even slightly on your earlier comment about SDCC. I'm curious and I did check to see what I could find about what few words you offered, found something that seemed close, and if so it seems to be a bit out of date.

My impression is that for better or (probably) worse, everybody is trying to please people who are accustomized to MS Visual studio. I can't get the hang around "project's" and "debug" directories and such, but I know where it comes from. > >Regards, > >Chris Groetjes Albert -- -- Albert van der Horst, UTRECHT,THE NETHERLANDS Economic growth -- being exponential -- ultimately falters. albert(a)spe&ar&c.xs4all.nl &=n http://home.hccnet.nl/a.w.m.van.der.horst |
