IMPORTING GITHUB PROJECT (SSD1306)

[Nasib]

Hi all. 

I am using Keil for programming a nrf51822 & SDK 12.3 

I want to use the SSD1306 OLED Drivers in my project 

I follow these steps: 

1) I copy .c and .h files form github to  ~\SDK\nRF5_SDK_12.3.0_d7731ad\components\drivers_nrf\OLED
2) My project is here:  ~\SDK\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\project) 

3) In KEIL I import those . c and .h files to nRF_Drivers folder
4) I compile the project and everything is ok 

Here is the problem: 

* when i try to add #include"SSD1306.h" my compiler says : "file not found"


WHAT AM I DOING WRONG??

I always use an example project and from tehre i use to modyfy the code.. but i have never add new drivers to an existing project... 


Thanks a lot

What, exactly, do you mean by that?

Where are you "adding" it? How, exactly, are you "adding" it?

usually indicates an Include Path problem:

I follow exactly the steps in this answer: https://devzone.nordicsemi.com/f/nordic-q-a/19267/having-issues-adding-drivers-to-a-new-project 

Now i can use #include "SSD1306.h" library but when i use any fuction included in SSD1306.c file the program launch the warning "implicit declaration..." what that means? 

Thanks!

"SSD1306.h" library

It's not a library - it's just a header file.

It means that you haven't provided any explicit declaration;  so the compiler is just assuming  a default - or "implicit" declaration.

Note that this is standard C programming stuff - nothing specifically to do with Keil or Nordic.

Presumably, the declarations should be in the  "SSD1306.h" header file ?
