LM9833 USB Communications

Tim Arnold

Is there any support information relating to the LM9833 USB comms interface? I need to determine whether control or interrupt transfers are used to access the chips internal registers. The data sheet refers to the 'LM9833 Software Package' for details on USB communication, but I haven't been able to locate that.

Thanks,

Tim

Hello Tim,

I've attached a document.LM983X SDG v2_0.pdf

Section 8 of the attached document describes the USB endpoints.

This document and some software source code is the extent of the support we can provide.

Regards,

Hooman

Thank you for the document, this will be very useful.
Section 9.1 of that document refers to a test bench and evaluation program '9832test.exe' and the 'LM983X.exe' TWAIN compliant software. Are these still available?
Also, you mentioned that some software source code is available - would it be possible for you to supply this as well? It may prove useful when writing our own software to interface to the chip.
Regards,
Tim
