[sane-devel] LiDE 500F: how to go further?

[Ralph Sontag]

Hi Pierre,

> >> I put my scripts here:

I made a new scan:

  0 ..   ~ 5 MB : USB starts
  5 ..  ~ 15 MB : ScanGear - the Canon-Program starts
 15 .. ~ 110 MB : Calibration.
110 .. ~ 200 MB : Scan (visiting card, 300, ca. 1.5 MB)
200 .. ~ 215 MB : ScanGear ends

So I have 215 MB raw log file, and after running the scripts 168.8 MB.

I've put it to http://www-user.tu-chemnitz.de/~sontag/sane/
(bzip2, 21 MB).

It's very usefull to pipe the file in "uniq -c" - it enlarges the size,
but we can jump over the block of identical lines.

At first lot of blocks of
0x55, 0x55, 0x55, 0x55,  0x55, 0x55, 0x55, 0x55,
are read. 
The last of this blocks ends at line 65433,
then the scanner starts writing blocks:

write_register(0x00)
set_write_register(0x2b, 0x00)
set_register(0x3c)
buf_prepaccess(0x0000f000,BULK_OUT)
Data: 01 00 82 00 00 f0 00 00
Index: 0
BULK>(61440)
  0xaa, 0xaa, 0xaa, 0xaa,  0xaa, 0xaa, 0xaa, 0xaa,
 
...

next block around line 73122:

  0xaa, 0xaa, 0xaa, 0xaa,  0xaa, 0xaa, 0xaa, 0xaa,
buf_prepaccess(0x0000f000,BULK_OUT)
Data: 01 00 82 00 00 f0 00 00
Index: 0
BULK>(61440)
  0xaa, 0xaa, 0xaa, 0xaa,  0xaa, 0xaa, 0xaa, 0xaa,

This repeats 4 times until line 98226:

  0xaa, 0xaa, 0xaa, 0xaa,  0xaa, 0xaa, 0xaa, 0xaa,
set_write_register(0x2a, 0x00)
set_write_register(0x2b, 0x00)
set_register(0x45)
buf_prepaccess(0x00040002,BULK_IN)
Data: 00 00 82 00 02 00 04 00
Index: 0
BULK<(65024)
  0xeb, 0xff, 0xaa, 0xaa,  0xaa, 0xaa, 0xaa, 0xaa,

- and I think, here the calibration starts with setting registers 
and write data.
But I can'nt interprete these registers ...

Greetings!
	Ralph.
