Hello (again),
|
|
<BR>
|
|
<P><EM>> Now I've finished my final exams at the university of Warwick I can
|
|
</EM><BR>
|
|
<EM>> devote
|
|
</EM><BR>
|
|
<EM>> some time to this project. I hope you can help me get started - I've got
|
|
</EM><BR>
|
|
<EM>> about 16 weeks to do this before I start work full time.
|
|
</EM><BR>
|
|
<P>Excellent to hear.
|
|
<BR>
|
|
<P><EM>> <A HREF="http://www.warwick.ac.uk/~phucq/scanner/usb-init-3.txt">http://www.warwick.ac.uk/~phucq/scanner/usb-init-3.txt</A>
|
|
</EM><BR>
|
|
<P>I can't make much of anything out of that either, but when you get the
|
|
<BR>
|
|
actual data transfers pinpointed I can compare it against the 630P protocol
|
|
<BR>
|
|
if you like. Hopefully there will be some parallels (I'm sick of this pun
|
|
<BR>
|
|
already).
|
|
<BR>
|
|
<P>Some things you could keep an eye out for that are part of the 630P
|
|
<BR>
|
|
protocol are:
|
|
<BR>
|
|
<P>* Each command ends with an 8-bit checksum
|
|
<BR>
|
|
* Most packets coming back from the scanner end with an 8-bit checksum, too
|
|
<BR>
|
|
* The scanner is 5104 pixels wide (330P is 2552 pixels) and just about all
|
|
<BR>
|
|
the measurements
|
|
<BR>
|
|
are calculated according to that value
|
|
<BR>
|
|
* The scanner returns a 38 byte ID packet with a 30 byte ASCII string in it
|
|
<BR>
|
|
(easy to find)
|
|
<BR>
|
|
<P>Hope you can make some good progress, support for USB scanners is far more
|
|
<BR>
|
|
important than clumsy old parallel ones these days. Good luck.
|
|
<BR>
