I was just busy fault finding a VFD unit that had broken and came across a CPLD IC from lattice.
I looked into CPLDs a bit a year ago for some high speed counting application, and the only ones I found much info on at the time were from Altera. The packages are certainly powerful, but seem to be a little expensive, and also they don't have any small package / pinout ICs.
The lattice ones seem cheap and also available in 32 pin packages, so could be ideal for small projects, I see the software is free (the price we like!) and you can buy cheap programmers from china so I might investigate further. However I notice Xilinx also have similar products....SO the question is, what's your experience with such devices, which are nicest & easiest to use - including IC, programmer and software?
