: I don't know what else to do apart from buy the Dev Board. I need it, don't I? I need to be able to test the ins and outs and have it working fast.
Well, the devboard comes with a C compiler, which you may or may not want to use. In any case, there are free assemblers and C compilers out there. I bet that's a big chunk of the price, based on the compiler they are including.
: I've only got a few months to get this working, i don't think i have time to make a Dev Board aswell. Am i wrong?
The devboard is primarily to play around with, mostly with code. However, most microcontroller projects need some outside hardware that needs to be built anyway. Plus, once the project is done, you'll need to build the prototype anyway. Why not start right out doing that?
:is it intrinsically simple? am i missing something? is it possible that 350 (~$500) worth of kit is producable in a short time?
I'm of the "nothing's simple" philosophy, but again, it depends on what you're doing. It really isn't that hard to get a microcontroller up and running, just for testing.
: I haven't seen any kind of Schematic for the Dev Board but that's the essential link if i'm going to do this.
Have you gotten as much information as possible from Cypress? Their website has some info, but usually these companies have pretty detailed data books.
Also, it may be worth the price of a phone call to call the company and speak with one of the hardware developers. I've done that with other companies, and managed to whine and beg enough to get them to FAX me the schematic of the development board. It took one phone call to find a sympathetic ear, and get him to FAX me.
: I've never taken on such a challenge before, i'm going to need the help of you guys. I'll be posting regularly as it progresses!
Well, it can be fun, though deadlines tend to temper that.
: Thanks for all your help
No prob. By the way, have you looked at all the 8031/51/52 sites on the web? There is so much info out there on these things. Not necessarily for Cypress chip, but on the microcontroller it's based on.
As I mentioned in an earlier post, I've rekindled my interest in these lately, and am starting to play around with them again.
Are you doing this project on your own? have you used 8031/51 before? Can you program in assembler or C?
Try posting as much info as possible, with as much detail on the project as you are comfortable doing.
