FPC only supports 32 and 64bits platforms. I recommend using commercial Pascal compilers for 16 bits / 8 bits. You may even be able to find some free software ones, but I'd inspect their quality first, because they may be unsuitable for commercial projects. > I've been > tempted lately to start making little circuits with microcontrollers on > them.

If it's too expensive for your product, then you can choose a cheap microcrontroller. It's trivial to find commercial Pascal compilers for microcontrolers, like 8051: http://www.google.com/search?q=8051+pascal+compiler&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:pt-BR:official&client=firefox-a Or PIC: http://www.google.com/search?q=pic+pascal+compiler&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:pt-BR:official&client=firefox-a If you still don't know which microcontroler to use I'd go for one of those options. PIC is by far the cheapest of all of them. The programming hardward cost is incredibly cheaper then for other ones. PIC is very popular one for cheap / simple projects, and I've been using it in project with great success. It also has a nice forum to ask questions, which was quite important for me. If you want something a little better, then 8051 is very popular in the industry is various fields from automotive to CNC machines. If you want even more power, then go for a ARM. There are even some embedded x86 microprocessors, but they are expensive if you are building something simple and cheap. > Also since there is no OS on these devices does > that mean that for sure fpc cannot work? I think this doesn't make any difference. The only thing is that if there is no OS then you also have no RTL, i.e. if you want one you have to write your own. Commercial compilers should provide a small RTL. -- Felipe Monteiro de Carvalho _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
