Genesys_Frontend structure is defined in genesys_low.h
typedef struct
{
u_int8_t reg[4];
u_int8_t sign[3];
u_int8_t offset[3];
u_int8_t gain[3];
u_int8_t reg2[3];
} Genesys_Frontend;
In version 1.0.17 Genesys_Frontend for HP 2400 was written as
- {{0x00, 0x03, 0x05, 0x02}
- , {0x00, 0x00, 0x00}
- , {0xc0, 0xc0, 0xc0}
- , {0x07, 0x07, 0x07}
- , {0x00, 0x00, 0x00}
which i replaced with
+ {{0x00, 0x31, 0x1f, 0x13}
+ , {0x08, 0x02, 0x16}
+ , {0x20, 0x80, 0x10}
+ , {0x80, 0x00, 0x00}
+ , {0x01, 0xff, 0x00}
by taking corresponding values of following registers mentioned by you
with help of Windows usb log
AFE |Genesys_Frontend
Register| member
--------+----------------
0x00 |.reg[0]
0x01 |.reg[1]
0x02 |.reg[2]
0x03 |.reg[3]
0x04 |(reset)
0x06 |.reg2[0]
0x08 |.reg2[1]
0x09 |.reg2[2]
0x20 |.offset[0]
0x21 |.offset[1]
0x22 |.offset[2]
0x24 |.sign[0]
0x25 |.sign[1]
0x26 |.sign[2]
0x28 |.gain[0]
0x29 |.gain[1]
0x2a |.gain[2]
Also i found you mentioned reset register which is not present in
structure declaration.
But i am not getting what to send for which frontend registers are
played with during
calibration?

Typically the .sign part is identical for all color channels.

Writes to the reset register lead to a reset of the frontend.

Sorry, i was not very clear.
I wanted to know which frontend registers are written to in your windows
log. Some registers always get the same values, while others are set to
varying values during calibration. I am guessing this frontend is
incompatible with the current implementation.
I get these information for my scanner:
[0x01] = 0x03d
[0x02] = 0x008
[0x03] = 0x000
[0x05] = 0x005
[0x06] = 0x000
[0x08] = 0x019
[0x09] = 0x006
[0x20] = 0x0e1
[0x21] = 0x0e1
[0x22] = 0x0e1
[0x24] = 0x000
[0x25] = 0x000
[0x26] = 0x000
[0x28] = 0x093
[0x29] = 0x093
[0x2a] = 0x093
Actually, the windows driver keeps the gain and offset constant for my
scanner.

Pierre
