Using Arduino Programming Questions

Hey guys,

is there a way to use other libraries, for example the Ethernet library, in own, custom libraries?

Kind regards

Hello Max

is there a way to use other libraries, for example the Ethernet library, in own, custom libraries?

Yes.

For example, I wrote a library which uses the SPI library. In my .h file, I include this ...

#include <SPI.h>

Then, in the begin() method of my object class in the .cpp file, I call the SPI methods I needed ...

ferroResult Hackscribble_Ferro::begin()
{
	// Initialize SPI
	SPI.begin();
	SPI.setBitOrder(MSBFIRST);
	SPI.setDataMode (SPI_MODE0);
	SPI.setClockDivider(SPI_CLOCK_DIV2);		
...	
}

EDIT: I include both the SPI library and my library in the .ino file ...

#include <SPI.h>
#include <Hackscribble_Ferro.h>

Regards

Ray

Due to limitations in the Arduino IDE, any libraries that you include in your own library must also be included in the sketch in which your library is used. Also, any libraries that those included libraries rely on also need manually including in the sketch.

It's a bit of a pain, but that's the Arduino IDE for you...

You could always switch to UECIDE which fixes that issue amongst many others.
