Do you run with an OS ? I know we can run without one but then we lose task= ing, nested subprograms and exception handling, no? So I work with scientific instruments. Sometimes I modify them for people b= ut I basically just repair them. I have thought about designing one for a l= ong time. It would take a lot less time and I would end up with a better pr= oduct if I could do it in Ada rather then C/C++. If each instrument will have a desktop computer beside it anyways, does it = make so much sense to struggle with a small embedded design. Side note, I g= et beat up everytime I dare to use the word embdded. I mean a memory constr= ained device without an OS. If I have a desktop computer the main issue wou= ld be interfacing it to an external circuit that has no firmware or at leas= t none that I wrote. I was wondering about using SPI with a GPIO card but I have not done this b= efore. I know there are also USB-GPIO adapters. Am I making things clearer or worse ? :) I have to run out for a few hours. -Patrick
