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.
