USB. Where to start?

[mrpicing]

Greetings!
I want to learn USB interfacing between PIC & PC.
I want to build a data logger as a trial project. It will read some analog signals through ADC.I dont know wher to start.
What should i try USB1.0 or USB2.0?
Can any body help me?
Thanks.

Look in this boards code library. The CCS USB2.0 driver code does the heavy lift reducing USB to the put and get forms albeit with a few modifications.
On the PC Microchip has drivers or you can use the generic HID Mass Storage type drivers the Softees have. I prefer the Microchip drivers. They are easy to call from within a PC delphi or C or Basic program with equivalents of Open get and put on the PC side. You PC and PIC code then moves quickly as all the prickly stuff is embedded in the familiar open close get and put operations.

I got pdf file from beyondlogic and reading it .
Can any body write a code for me .
It should be written in CCS for PIC16C765 or PIC16C745.
Programm should get a command from computer to control LED(On_Off).
and programm should report a button state connected on interrupt pin.
Thanks.

I'm working on a product using the FT232R interface chip from FTDI. It's been really easy to work with from both the PC side and the PIC side--as far as the PIC is concerned it's a serial port, and as far as the PC software is concerned, it's also a serial port even though it's actually USB. I don't know how they do this and I don't care!

No connection with FTDI except as a customer.

Can any body write a code for me?

Uh, no. Not unless you pay me. But if you can get a serial port working, you can do this.

asmallri,

what about data speed with FT245?
