I'm looking for resources on using D for basic Raspberry Pi programming...stuff like turning on and off an LED light. I believe it requires being able to call the Raspberry OS core APIs from D as available in Python.

Anyone here tried something like that using D?

I haven't tried with D yet, but I use C# and mono calling into the pigpio C library (http://abyz.me.uk/rpi/pigpio/pdif2.html) and it workes great.  You should be able to do the same with D.

Just found this package dating back from May 2016...let's see what it can do (https://github.com/fgheorghe/D-Lang-Raspbian-GPIO-Module)

I've been using https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/ . It is a C library written by Bartosz Golaszewski. He is actively working on it. The latest update is a week old. It has the advantage that you don't have to use sudo to access the gpio pins. It comes with a set of tools written in C that I have been converting to D. Since my knowledge of both D and C is weak it has taken me some time to get things going. I have a hand written D bindings file that is incomplete and of amateur quality. So far I have converted 2 of the 6 command line tools that Bartosz Golaszewski provided to to work with the library.

your code... can you push it to GitHub so I can check it out?

I have no idea how to do that from D. Any help/resources on that?

You should be able to use the techniques at https://dlang.org/spec/interfaceToC.html to declare the C functions that you wish to use in your *.d source files, and then, when you compile, pass `-lpigpiod_if2` to the linker.

Maybe you can use this dub package? http://code.dlang.org/packages/dgpio

I'm using a D app on a raspberry Pi to open my house portal for 1 year now. It works perfectly. The "hardest" part is the compilation.

I tried this guide yesterday: https://wiki.dlang.org/Programming_in_D_tutorial_on_Embedded_Linux_ARM_devices and it worked perfectly fine. I compiled my app from Windows with a Debian (from the windows store) and uploaded my executable compiled with ARM target.

Thanks. Appreciate.

I haven't used GitHub or git. Is there some other way?
