I am programming with FreePascal and Lazarus towards a Raspberry Pi2 target platform. Doing so on the RPi2 itself is possible and basically works fine, except that the system is a bit sluggish at times and there are other inconveniences as well. So I moved to a Linux Mint 17.3 Mate system in a virtual computer (VMWare) on my Windows7 PC instead.
Most of what I am doing concerns non-hardware dependent things and works fine as far as I can see. But there is one snag, and this is the GPIO handling where obviously the GPIO access is not possible on a PC platform... So I need to put some kind of conditional into my code to redirect the GPIO calls to some simulator I will have to build. (I am assuming that there is no such thing available already of course). So I would like to know how I can create a conditional that uses the real GPIO if the build is done on the RPi2 itself and for the simulator otherwise. Something like: uses ... {$IFDEF RPi2Hardware} PiGpio, {ELSE} PiGpioSim, {$ENDIF} Then I could create a PiGpioSim unit as a simulator that defines the same object class but does not target the actual hardware on RPi2 but some other mechanism that I can monitor while debugging in the development PC. Is there something like "RPi2Hardware" already set up that can be used to check for this? -- Bo Berglund Developer in Sweden -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
