Wow. That SPI interface is a lot simpler than I thought it would be. Nice!
But this doesn't address the issue of using a laptop that does not have a LPT port. Still it is a slick solution. Thanks for sharing that. I would think that JT would want to use a newer laptop for this app - which would not have a LPT port.. after all we are talking barbecue. :-) There are a few memorable places I have had really good smoked barbecue. Kansas City - I camped out there for months back in the 80's. Land between the lakes Kentucky (a customer insisted that we go there for dinner - he didn't mention that it was over an hour away!), several locations in Texas, and a place in North Carolina where we waited in line for about a half an hour due to the crowd at lunch time. The Montgomery Inn / Ribs King in Cincinnati is right up there for ribs, but I don't think they smoke their ribs, so they might not count.
