USB and PIC, friends or foes ? - Electronic Circuits Projects Diagrams Free

TiagoSilva · 24th May 2008, 04:00 PM

Hi, well, isn't this an nice topic ? well, where can i find some simple projects using USB with the on-chip PIC USB interface, on PIC !
The PIC subject is the PIC4550 and i'm interested on C language side of the story, any compiler that works this out.

I hope Nigel can make his 14th tuturial abouth this !

Have a nice weekend

C18 is the Microchip compiler and has the USB examples. The SE edition is free. Lots of code examples on the net.

As often suggested here, look at the USB Bit Whacker

UBW (USB Bit Whacker) Project

Hi Nigel,

Ok I am going to ask the question, what is "bit whacking"?

It's like bit banging, only harder!

That was funny Futz! I don't know why but got a good laugh of of it.
Perhaps because I'm knee deep in reading a data sheet.

Thanks,

A trip to double-u-double-u-double-u.microchip.com (no, no redirect) would reveal that they only support C language for the USB versions of their products. They provide examples and application notes up the wazzu for one and zilch for the other language. Yet still, the world cries help while I cry what a joke.

What's wrong with picking a language such as C as the officially supported language for the PIC 18F and above series, the C18 SE compiler is free, works with the entire 18F series and C is the language of choice for big projects anyway. I do like assembler but understand why Microchip chose C for the bigger projects.

This website is great for starting out as it has the basic schematics needed to emulate a USB dev board that the microchip tutorials use.

That's a handy link thanks.

I agree, I don't do C, but in this case they provide a free C compiler, which is used to write the application notes and datasheets, I see no problem in using C as they do.

Learn to read if not program C.

Imagine the problem for the person who speeks anything other then english or chineese.

LOL True, LOL

Thank you all for your support !
The USB Bit Whacker sounds great (LOL...)

I must also thank for this url (PICcoder - Articles), it was what i really needed ! Since i work best with C# (i'm a pc/pda/web software dev., but no expert in assembler).

Thanks again, and again.
