Hi Mathew,<br>
|
||
<p>
|
||
I really dropped the ball on this one. I had hoped to 'experiment' with<br>
|
||
my 4200 using the pdf docs from NatSemi...just havn't had time to sit down<br>
|
||
with it. I've forward this to the sane-devel list since that should be<br>
|
||
the best source for developers. I did ask Peter if he could recommend<br>
|
||
anyone and noone came to his mind.<br>
|
||
<p>
|
||
Regards,<br>
|

Subject: Re: [linux-usb] HP4200c,working?<br>

|

Hi Everyone,<br>
|
||
<p>
|
||
I am one of the designers of the chip that is at the heart of the HP<br>
|
||
4200c and would like to mention a few things about it here. As mentioned,<br>
|
||
this scanner does not use SCL. Instead, it uses its own, custom,<br>
|
||
protocall defined by the chip it is built around, the LM9830. This is the<br>
|
||
first Merlin chip from National Semiconductor. We used a custom interface<br>
|
||
because SCL would have required more expensive parts. We just released<br>
|
||
the LM9831, and will soon release the LM9832, which all both use an<br>
|
||
interface very similar to the LM9830. Scanners based on these chips will<br>
|
||
soon be for sale from many different vendors, not just HP. If you like,<br>
|
||
you can find out more information about Merlin at<br>
|
||
<a href="http://connect.to/merlin">http://connect.to/merlin</a>.<br>
|
||
Although we are not officially supporting linux, I am trying to get a<br>
|
||
linux driver together for our chips. It looks like the USB portion of the<br>
|
||
kernel is working, so what is really needed is a SANE back-end. If<br>
|
||
anybody is interested in helping with this, please let me know. I have<br>
|
||
access to the TWAIN driver code for windows and all the internal details<br>
|
||
of the chips, so there is no need to reverse engineer anything. I really<br>
|
||
don't have much experience programming this kind of thing, so I would<br>
|
||
really appreciate any help from anyone who does.<br>
|
||
<p>
