PC-to-uC via USB - schematics needed

[Laplace]

pc to uc communication

Has anyone got the schematics and/or design materials for PC-to-uC communication via USB instead of RS-232?

Thanks...

hi

if you mean PC in USB a and uc connected in RS232 (not in USB native) take a look here

u can also take a look at PL2303 , www.prolific.com.tw ...lots of usb devices there

Re: PC-to-uC via USB?

You have two choose :
* The first,you use a uC that integrated USB interface ,i know that some firm Texas,Phillip has uC have USB ,that uC compatible with xx51 product line,you must have compiler such as Keil C v7.0 and uVision to program for this chip.
* The second you buy a USB interface chip ,such USBNxxx of Philip and use data sheet and program for this chip and can communicate with PC by USB.
Good luck !

Microchip do two PIC's with USB, 16C745 and 16C765. Elektor recently (November 2003 I think) did a project using the 16C765. The hardware is trivial and software is readily available.

Is there a way of getting a duzens of this devices, without having to buy 1000 ???

thanks

asena,
maybe even 1000 is a small qty..indeed this is a problem , but you can search for distribuitors, or ask them for samples...

Re: PC-to-uC via USB?

Indeed i asked for samples, but got no answer so far.

I think you have to bug them with 1000's email and fax, so you can get attention.

Anyway, this is a good substitute for the FTDI or others, because they dont need any Virtual COM Port drivers. IMHO

Anyone has the Elektor article using the 16C745 and 16C765 - mentioned above ?

Thanks.

Hopefully this is the article you want:

Is the one (PIC16C745 or PIC16C765) shown in your website reprogrammable?

The Virtual Com Port driver is not mandatory for FTDI chips. You can use their API (embedded on dll) instead, that's what I did. If you want to buy few pieces of FT2232C I can sell them to you, look here:

Look at TI's TUSB3410 and their UARTEVM schematic - has everything ready to go for you, PC and uC side.
