cpld interface with AT mega8

Jan 28, 2005 7 Replies

Groan. I know English is perhaps not your first language, but even so, you must know that's a pathetic request.

What sort of a counter? What's it for, speed, size, up down etc. etc. Have you ever interfaced anything to a Mega 8, or to anything at all? If so, design the CPLD to interface like whatever you did before. If not, find out how to. Have you designed anything with a CPLD before? If not, find out how to. Then come back to us with any specific questions on the application.

Otherwise it's no use talking, even if we give you chapter and verse you won't be able to use it.

Oh, and we don't do homework.

You can do a an SPI interface, a parallel interface, whatver. It depends on how many pins you want to share and what time you want to spend on handshaking.

Groan is right Paul, I wonder if some people even think before they post a question.

or before poating a follow-up with zero useful context.

You can look at the applications notes for the FPSLIC to get some Counter code. Some of the examples contain counters You may also want to have a look at the FPSLIC itself, since it is much easier to do the counter with the possibility to simulate both the AVR and the logic.
