Posted on May 17, 2011 at 11:56 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.
Witt
