Hello all…

I don’t have so much experience with the C language and the USB protocol, and I need to utilize the routines for transmit/receive by this protocol, these routines are in the DK3200_dsn_2.zip archive. I have some doubts about the functions implemented in this archive. The questions are:

- What I have to set (variables, SFRs…) and which functions are necessary to call for transmit a data by USB?

- When I will know that I can transmit data by USB (USB is not in busy)?

- When I will have sure that the transfer or reception has been finished?

- Where are the data received and where I will put the data for transfer?

- Which are the differences between the SFRs UDT0 and UDT1?

These questions can be simple, but I couldn’t resolve than.

If somebody has a good tip about USB I would like to know.

Excuse for the used grammar.

Regards.
