How can I just use this project along with particle compile && particle flash

Running the project from scratch and doing particle flash XXX . gives this

Flash device failed
[object Object]

The Particle Community Libraries list your name but actually link to mpechner/Adafruit_SSD1306 on github so 404 error is generated.

Not sure what the next step would be without creating an Adafruit_SSD1306_128x64.h and Adafruit_SSD1306_128x32.h and importing the proper one (at when trying to use this library within the web IDE)

When prahaladm recoded for the arandom() change no one undid the changes in the rest of the file. I know I was having issues getting this to run with the function called random. Would the solution be to fall back to rand()?

I am trying to use a 128x64 spi oled with this code and a photon:
https://github.com/pkourany/Adafruit_SSD1306/blob/master/ssd1306_128x64_spi.ino#L33-L37

what I find confussing is that according to
https://docs.particle.io/reference/firmware/photon/#spi
SPI1 that is used here uses:

SS => D5 (default)
SCK => D4
MISO => D3
MOSI => D2

but the defines I linked to do

#define OLED_DC     D3
#define OLED_CS     D4
#define OLED_RESET  D5

so OLED_CS would be connected to the SPI1.SCK (spi clock) pin, were instead it should probably be D5
(CS = chip select -> SS = slave select)? Also which pin is actually used for the clock then?

and OLED_DC would be MISO instead of MOSI?

Furthermore shouldn't
https://github.com/pkourany/Adafruit_SSD1306/blob/master/Adafruit_SSD1306.cpp#L167

- SPI.begin()
+ SPI.begin(cs)

otherwise it will configure D5 for SS (even though its probably no hard since it will only configure it to be an output).

Here is how I am using it - SW mode works, but HW doesn't:

#if 0
  // HW SPI
  //#define OLED_DC     D3
  #define OLED_DC     D1
  //#define OLED_CS     D4
  // our module does not support CS/SS
  #define OLED_CS     D0
  #define OLED_RESET  D5
  Adafruit_SSD1306 display(OLED_DC, OLED_RESET, OLED_CS);
#else
  // SW SPI
  #define OLED_CS     D0
  #define OLED_DC     D1
  #define OLED_MOSI   D2
  #define OLED_CLK    D4
  #define OLED_RESET  D5
  Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);
#endif

Hey,
I am trying to get this to work with a sparkstump.
But I am getting

Adafruit_GFX.h:4:25: error: application.h: No such file or directory

Where do I get application.h from?
