Cheap hardware for newby + some questions

bmentink

Hi All,

I have just found out about this wonderful chip and am wanting to try it out on a limited budget.

Some questions:

1. I did see on this forum some PCB's for sale but can't find it any more. Can someone point me to where I can get these? I am particularly
interested in a USB comm/powered version.

2. Where can I get small samples of the chip, do Parallax supply samples or small quantities? If not, can someone point me to a cheap supplier ..

3. My 1st project will involve generating PWM signals, I can't seem to find a basic PWM object in the object exchange, the closest I could find is some motor drivers.
I guess I could hack these to suit, but if there is a basic PWM module, please let me know.

4. Has anyone written state-machine tables in spin or assembly, this requirement is top on my priority list for good coding .....

Thanks to all.

Hi. I'd get the book too. It's much easier to program when you don't have to switch back and forth from the internet to the editor.

Thanks OBC,

Useful links. I was actually wanting a source of bare PCB's, someone was selling them, they looked to be in DIP40 module format ..

Cheers,

Look for one of Phil Pilgrim (PhiPi) posts.

Hi Ariba, yes it was Phil Pilgri's boards I was looking for. However he doesn't ship to locations other than the US, so
that puts a damper on that idea ....I would be quite willing to may for USPS to New Zealand, it should be quite cheap for 4 bare boards ... oh well ..

Brian, I have seen those boards, but what I am after is really a cheaper version of the DLP-PROP ($69), if I can't get that I just might have
to bite the bullet and get one ....

Thanks, anyone have answers to my last two questions?

Also.... to answer a couple more of your questions.....

Parallax doesn't have a sample program like some other chip manufacturers. There are some instances that they have given away samples that I have read about in the forums, but for the most part, I'd say you'll have to buy your Propeller. (most demo boards that were mentioned in this thread include a Propeller)

A cheap supplier, Well, all suppliers that I know of in the USA charge the same as Parallax themselves. I have gotten Propellers from Parallax, Digikey and Mouser.
