Hi Trevor
That’s great news, I am looking forward to the Autumn already.
Hi Jeffery
I am afraid I haven’t learnt VHDL. I was going to and had downloaded a tutorial but then I discovered that the design could be entered as a schematic. For someone like myself that has no previous experience this is a quick and easy way of programming CPLD's. I will post a screen shot later. I would expect that you would have more functionality with VHDL and that it would be easier for more complex designs.
There is about 8k bit's of memory in this CPLD which should be enough for one line store if it is suitable type of memory, but as yet I don’t know what type it is, more reading to be done.
CPLD's with more resources than this one are available and as you say even FPGA's aren’t expensive. For now I will keep playing with what I have until I get the basics right and then see where to go from there.
