USB chip

Started by Mr No October 7, 2003
Hi!

I'd like to know whether i can communicate PIC with USB. Can i
read the output form USB port?
Thanks in advance for any suggestion.

Rgds.

There is an USB PIC, but it is an EPROM type. There are rumours of an
18F (flash) PIC with USB, but I have not seen it yet.

I would suggest using an FT232BM (USB-to-serial converter chip).

I too would LOVE to see a USB EEPROM based PIC.  It would open up a whole new market for Microchip using them as interface controllers for PC's.  I can't believe they've neglected this market for so long.  The world really needs a single-chip USB microcontroller solution, and it would make sense for Microchip to position the PIC for that.

They do exist, from Cygnal, Philips and others.

Good point. 
I guess I just don't understand why Microchip hasn't provided a PIC based solution. 
Especially if they could make it easy to interface and offer "nearly done" template USB drivers for Windows and Mac.

What about the 16C745/765? 
 
I just layed out a board to use these parts.  Is there something wrong with them?  Are they faulty or overly hard to get working?

The PIC's are not really designed for this kind of application. You
don't use a hammer to put in a screw.

uChip *has* a PIC-based solution, but not a flash PIC. Maybe that does not matter much for developers with a hughe budget (who use ICE's and other expensive tools), but it makes it more difficult for a small-budget developer.
 
But again, there is the FT232BM (or FT245BM).

I regularly do. And I use a screw to make or enlarge a hole. Or maybe my
solder iron when it's plastic. And I use my teeth when I can't find my
wire stripper. And I use a computer (instead of a calculator) to
calculate sqrt(12)-2*0.7. And I use a PIC to blink a LED or display
'hellow world' on an LCD. And ...

So why not develop using the windowed CERDIP and once you have the code right use the OTP parts?
 
I have yet to get an ICE, but I really want one.  Like you said though, budget prevents that when a few windowed parts will do the trick.
