Though at the time I was doing this stuff you had to had the official ATMEL programmer... Maybe things have changed now.. @agranlund @PhilC ?
I don't think I did, need to go have a look what I've got, but as I said, I think they came pre-programmed for me as evidenced by the flag sticker on the CPLD, not something I'd do..

Had a route around and found the latest boards ! Question is, can I be really bothered to build one of these up :lol: :roll:

Looking at the schematic, I am already puzzled, because for some reason I removed the series resistor off the LED :shrug:

ahhh

viewtopic.php?p=34718&hilit=led#p34718

I thought the only possible way will be either multiplexing or a fixed resistor built into the LED which I don't normally use..

So yay me for writing this stuff down somewhere! :D :lol:

Only possible problem is this likely assumes a CF card being standard in how it operates.. So I guess if the LED catches fire.. put a 1K in series with it.. :lol: :roll:

@exxos there are other methods now to program them now, even copy atmel programmers apparently, I've got a proper one that I got through eBay..
If it ain't broke, test it to Destruction.

It's also a reminder how completely annoying through-hole soldering is !
