GAL / PAL programmer - Electronic Circuits Projects Diagrams Free

bonxer · 9th March 2005, 10:46 PM

Back when I was an undergrad, we did some GAL or PAL programming (not sure which of those, or if there even is a difference in the two terms). They were made by Lattice. I don't remember what kind of programmer did the actual fuses, nor what software we used. So I'm wondering three things: Is there a place I could get a good pre-made GAL/PAL programmer (under US $50), a good place to get GALs/PALs, and what software is available to program them. I feel like such a noob asking the same PIC questions. :P

I am taking a digital class in college right now. We are learning about how the GAL's work and will be programming them soon. Give me a few days and I'll get back to you on the software and hardware we will use.

CPLDs (the same idea but with more logic) often use JTAG. Xilinx has free software for their CPLDs that lets you bitbang JTAG through the parallel port. ISE Webpack it the free design software. Digikey has Xilinx CPLDs for under 5$.
