Using C# and GPIO - Raspberry Pi Forums

hello everybody,

i'm new raspberry i'm senior developper in c#. i'm using raspberry house automation (so i've added razberry), , particulary analyze electrical/water/gaz consommation.
first step using pulse counter, connecting them gpio. i'm confortable c#, i'd use achieve goal.
there's not c# on raspberry compare c/c++ or python, that's why i'm asking guys advice me what's best library ?


lot !

you need download attached zip file, 2 files need in exe path. plus, need make reference dll.

console app turn on leds

using system; using raspberrypidotnet;  namespace test {     class program     {         static void main(string[] args)         {             gpiomem led15 = new gpiomem(gpiopins.v2_gpio_15);             gpiomem led18 = new gpiomem(gpiopins.v2_gpio_18);              while(true)             {                 led15.write(pinstate.high);                 system.threading.thread.sleep(200);                 led15.write(pinstate.low);                 //system.threading.thread.sleep(50);                 led18.write(pinstate.high);                 system.threading.thread.sleep(200);                 led18.write(pinstate.low);                 //system.threading.thread.sleep(50);              }         }     } } 

here very simple winform app run in rasbian x desktop. reads state of switch , outputs leds.

hope helps, , basic without error checking. needed test stuff out.

here pinout
