Dear Dirk -

Your thesis looks very interesting.  I am working on a very similar problem, 
connecting a CMOS imager to a Linux computer via a USB port.  I would love to 
comare notes about your findings.  I have successfully (more or less) 
connected the imager chip (which has since become obsolete, a common fate 
among CMOS image chips) using a BF535 DSP chip produced by ADI (Analog 
Devices, Inc).  There are a few difficulties that I have found:

1) The stock emulator and development tools run about 10,000 dollars, US.  
That may be a bit steep for a thesis budget.

2) The emulator environment only runs on Windoze, which is icky for most Linux 
guys.

3) The stock example board produced by ADI does not include access to the USB 
port, and the chip is a ball grid array (ie, you're out of luck if you wish 
to jumper the pins).  That means that you have to make a custom board, 
unhappy.

The BF535 has a built-in USB port, but alas does not have a parallel port to 
import the picture signal emitted from most imaging chips.  There may be an 
easy workaround using the memory bus.  The Blackfin family (which includes 
the BF535)  includes varieties which have the required parallel port, but 
does not have the USB port.

Interestingly, I have read recently of a uCLinux port to the Blackfin core 
instruction set, but have not had the time to properly investigate.

I hope this helps.

Hello everybody,
 My name is Dirk, I just started doing a diploma thesis about "Connection 
 of an astronomical CCD camera to a linux computer via USB"
 The CCD puts out the data in a given digital format at a given clock rate. 
 I"m asked to install a mircocontroller (with build in USB support) taking 
 the data and sending it via USB to a PC runnig linux and to write a driver 
 storing the data in a given format. From this two questions arise:
 
 1) Has anybody got any experience with any spezific microcontroller with 
 with USB support.
 
 2) I need literature about the Linux USB subsystem.
 (I allready got  Universal Serial Bus Development for Linux by G. Acher & 
 D. Fliegl)
 
 Yours
   Dirk Huenniger
