A smallish starter Kit for led control

[LM]

I would like to see what kind PWM LED control I could do with FPGA and
of course just play with the kit to see what else I can do with it. A
FPGA (kit)with plenty of pins and low price is good.

I am not willing to re invent all the the wheels there is and
programming some PC interface, so the kit or FPGA should have some
communication port built in. There are plenty of LED controllers
already, so that wheel I am happy to reinvent.

You have not actually asked a question and 'LED Control' is a very
broad field.
A 16V8 can PWM control a LED

Assuming you want pointers, a nice minimal system, with on chip RAM,
is the LCMXO2-1200ZE-B-EVN.

Mouser show 68 in stock for $29.99

This has a FT2232H (Dual,HS), one Chan for JTAG,and the other Chan
connects to Logic, for your use.

We have a range of solutions but a lot depends on what sort of drive
you want and how that is going to be implemented. For low cost board
look at http://www.enterpoint.co.uk/polmaddie/polmaddie3.html. 60 3V3
I/O there and the 3 headers are on 0.1"/2.54mm grid so you can make
stripboard lash-ups to add on.

I guess I did not put a question here. But you guessed correctly, a
starter kit pointer or name is what I want. It seems I'll know a good
starter kit, when I dont need them any more. 29.9$ is surely a good
price. I am willing to pay a little more though. That board 3 from
Enterpoint is surely one alternative.

Some more info of what I have in mind. A decent ("centipede") cpu has
about 40 free IO pins. That means it could PWM drive that much LEDs. I
am thinking a very simple way, just controlling one LED with one pin.
Programming may become difficult because of timing and so on. I think
I could better describe a PWM control with logic, and timing seems to
be easier.

I need also a bus to get data from PC. What the bus is, is not
important now. Of course, if I have to program it my self, it should
be simple.

Many pins, heh, more than 18. Basic logic outputs, Cmos levels and
speed. I am not going to drive LEDS with FPGA outputs directly. What
is there in the kit is a different matter, but buffers are easy to
build.
