Hm, what's the exact response to 'Inquiry'. And what do you mean<br>
|
|
by 'limited manner'? <br>
|
|
I'm working on a backend for the ScanExpress models (based on the<br>
|
|
specs Jan Krueger got). Currently gray and lineart is ok, color<br>
|
|
more or less (except line distance correction). <br>
|
|
<p>
|
|
That's what I know at the moment:<br>
|
|
<p>
|
|
All 16/32 Bit values in big endian!<br>
|
|
<p>
|
|
Read/write calibration data can be completely omitted.<br>
|
|
<p>
|
|
Set window:<br>
|
|
Resolution in dpi, below 60dpi don't work. <br>
|
|
<p>
|
|
Upper left coord. and window size in 1/1200 in for 12??? models,<br>
|
|
in 1/600 in for 6??? models.<br>
|
|
<p>
|
|
Threshold: Ignored<br>
|
|
<p>
|
|
Image comp: Ignored <br>
|
|
<p>
|
|
Bits p. pixel: only 1 (=>lineart), 8 (=>gray), 24 (=>color),<br>
|
|
there is no halftone mode <br>
|
|
<p>
|
|
Send data:<br>
|
|
Gamma: cmd[2]=0x03<br>
|
|
cmd[6]=0x00 => gray, 4096 Bytes, cmd[7]=0x10, cmd[8]=0x00<br>
|
|
cmd[6]=0x01 => red, 4096 Bytes, cmd[7]=0x10, cmd[8]=0x00<br>
|
|
cmd[6]=0x02 => green, 4096 Bytes, cmd[7]=0x10, cmd[8]=0x00<br>
|
|
cmd[6]=0x03 => blue, 4096 Bytes, cmd[7]=0x10, cmd[8]=0x00<br>
|
|
cmd[6]=0x04 => threshold (lineart), cmd[7]=0x00,<br>
|
|
cmd[8]: bright -> 00 ... 80 ... FF <- dark<br>
|
|
no further data!<br>
|
|
<p>
|
|
Read Data:<br>
|
|
cmd[6] seems to be don't care, despite the strange code in<br>
|
|
the sample driver.<br>
|
|
<p>
|
|
And: If supplied SCSI card is used, disable USLEEP code (in<br>
|
|
g_NCR5380.c). The scanner silently overwrites its buffer (128kB)<br>
|
|
if data isn't requested fast enough!!! So one gets a corrupted<br>
|
|
image (some horizontal stripes missing or appearing several<br>
|
|
times, shifted horizontally etc.) Grrrrrrrrrrrrrrrrrrrrrr!<br>
|
|
<br>
|
|
I haven't figured out yet how the colors are interleaved and <br>
|
|
line distance has to be interpreted.<br>
|
