B4R Question Adafruit_ADS1015 automatically deleted from sketch folder

[Hans- Joachim Krahe]

hi, I try to #include <Adafruit_ADS1015.h> //"Adafruit_ADS1015.h" . Does anyone know, what's wrong? ?

--------------------------------------
Erel:
1. You have posted this thread in B4R Libraries forum. Only actual libraries should be posted there.
----done

2. Never add files to the internal libraries folder unless the instructions specifically say so.
----never will do again

3. The internal libraries folder is not searched for anything during compilation.
---- understood

You can install the library with Arduino IDE and change the include command to use <Adafruit_ADS1015.h> instead of "Adafruit_ADS1015.h" or include the files inside the folder of one of the already referenced libraries. This way it will be copied to the project folder during compilation.
/Erel


-----------------------------------
I installed Adafruit ADS1X15 in Arduino IDE

I changed the include command to use <Adafruit_ADS1015.h> instead of "Adafruit_ADS1015.h"

I cleaned the project.

I copied Adafruit_ADS1015.h and Adafruit_ADS1015.cpp to the Rwire folder in additional library, which is used too in sketch

result:

Adafruit_ADS1015.h and Adafruit_ADS1015.cpp NOT copied to sketch folder.

? ... what todo or tobe?

by the way, after installing Adafruit ADS 1X15 to IDE, it is not shown in Arduino libraries - is there another folder too?

I think that you need to understand how B4R works.
I hope more people will help me to explain.

In B4R you can only use B4R libraries.
A B4R library can build on an Arduino library.
The creator of a B4R library must explain how to install the C files or include them in the library.
In this example someone has wrapped an Arduino library to be used in B4R.

If you use Arduino to install a library, it will not be available in B4R.
But if it is installed by Arduino you can use inline C to use it.
In this example you install Narcoleptic in Arduino and use inline C.

Thank you, but after installing Adafruit_ASD to Arduino IDE, the error upon ecured ond I don't understand, why. ?

 

[Erel]

Here is what I did:
1. Installed the mentioned library with Arduino IDE.
2. I've opened Arduino libraries folder to see what was actually installed:

The file name is different than what you wrote.

3. I've added a reference to this header file with:

#if C
#include <Adafruit_ADS1X15.h>
#End If

It compiles.

... hm, I had changed the Arduino libraryfolder adress. Set it back to Documents/Arduino and it works. But was missing Adafruit_i2c then. I installed Adafruit IObus then and got errors:

"E:\Documents\Arduino\libraries\Adafruit_BusIO\Adafruit_SPIDevice.cpp: In member function 'void Adafruit_SPIDevice::transfer(uint8_t*, size_t)':

is there another library that works?

arduino example from github makes same error. Seems to be incompatibility between latest libs adafruit_ADS1X15 and adafruit_busIO..? ?
