'PIC driven Linear CCD'
|Anyone had experience with linear CCD's?
I have a project which has been on the shelf for a few years, but I
have recently acquired the necessary device to be able to make a start.
The chip in question is a Toshiba TCD2301C RGB Linear CCD, and their
like rocking horse sh** (very hard to get hold of).
Can anyone recommend a good book (available in the UK) for the basics of
PIC work. My net surfing atm has come up with one called Easy PIC'n
written by David Benson and published by Square 1 Electronics in the
USA. I would have to make a special order to get it through our Uni
bookshop. A couple of months for delivery and costs 47 quid.
The CCD needs to be clocked at about 1MHz (4MHz max). TTL clocking
i.e. 0 to 5V DC and 12V DC power supply. Another requirement is very
fast AtoD, and the final stage in development will be to run a
stepper motor in parallel with the CCD.
It has been suggested that I get a PIC16C55 to drive the system, but
this advice is a couple of years old now.
Any help to get me started on the right tack would be very gratefuly
received. My knowledge of electronics is pretty basic, but the only
analogue requirement is for the AtoD conversion, so once I get
started I should move on fast.

I've done A/D work with a PIC16C74 with great success. The speed isn't
terribly slow either (about 20 us. conversions) ONly 8-bit's on the built in
A/D. If you want to get the project done without alot of messing around, I
suggest getting a "C" compiler to speed things along, and use a ready-made
stepper controller to avoid messy problems with those...

Might I suggest you look at the 16C71x PICs. They have ADCs built in.
Only 8 bits, but a 20us conversion time.
