B4R Question frequency counter

[Jpiti]

Hello,
i would like to build a frequency counter with an arduino. I found this lib and example proramm:

http://interface.khm.de/index.php/lab/interfaces-advanced/arduino-frequency-counter-library/

Is it possible to embed this with the Inline C function in B4R?
I need the frequency as value in B4R?
Can anyone help me please?

Try this:

Sub Process_Globals
   Public Serial1 As Serial
   Private frq As ULong 'ignore
   Private timer1 As Timer
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   timer1.Initialize("timer1_Tick", 20)
   timer1.Enabled = True
End Sub

Sub Timer1_Tick
   RunNative("FreqCounterStart", Null)
   RunNative("FreqCounterGet", Null)
   Log(frq)
End Sub

#if C
#include <FreqCounter.h>
void FreqCounterStart(B4R::Object* o) {
FreqCounter::f_comp= 8;        
 FreqCounter::start(100);  
 while (FreqCounter::f_ready == 0);
}
void FreqCounterGet(B4R::Object* o) {
   b4r_main::_frq = FreqCounter::f_freq;
}

#end if

The library should be copied to the arduino libraries folder:

Many thanks Erel.
I will test it soon.

I tested the code. The code runing. I have set the timer1 interval to 1000.

Thanks Erel
