Hello,
This is my first tme asking a question here. I am trying to setup this library in my vs code project, but it is not registered in the particle workbench registry. I dont usually use vs code, but i have a project where i have to.
And sorry if this have been asked before, but i cant find a topic where u import a libary from github to vs code.
I dont want to use the project like he suggest.
Welcome to the community.
If you have github login - then if you go to the link above you can download the code as a zip file which you unpack in the directory of your project in VS Code/Particle Workbench. If you are using webIDE then I would cut’n’paste the files from github.
I have tried that, but i still get samme error.
Does it have to be inside the lib folder? or inside the project root?
Welcome to the community 
This repository is not providing a library as such but only a project that can work with that display.
That's most noticeable by the fact that there is a project.properties file and not a library.properties file.
If you want to use this as a library, you'd
Particle: Create New ProjectParticle: Launch CLImkdir lib lib/Adafruit_ST7789 && cd lib/Adafruit_ST7789 && particle library create --name Adafruit_ST7789 --version 0.0.1 --author "Adafruit (ported by Jens Chr Brynildsen)"particle library add Adafruit_mfGFXAdafruit_ST7789.h & Adafruit_ST7789.cpp files in the repo into the respective files in lib/Adafruit_ST7789/srcST7789_test.ino into the examples/usage.inoNow you should be setup to use that library in your project
BTW, when you say
what error would that be? 
Thank you for welcoming me 
fatal error: Adafruit_mfGFX.h: No such file or directory
I run particle library add Adafruit_mfGFX?
Can you check whether there is a dependencies entry in the library.properties file for Adafruit_mfGFX?
OH sorry,
here:
name=Adafruit_ST7789
version=0.0.1
author=Adafruit (ported by Jens Chr Brynildsen)
# license=insert your choice of license here
# sentence=one sentence description of this library
# paragraph=a longer description of this library, always prepended with sentence when shown
# url=the URL of the project, like https://github.com/mygithub_user/my_repo
# repository=git repository for the project, like https://github.com/mygithub_user/my_repo.git
# architectures=a list of supported boards if this library is hardware dependent, like particle-photon,particle-electron
dependencies.Adafruit_mfGFX=1.0.4
Sorry, I just realized: Since this library was not pulled in via Particle: Library Install the dependency won’t be followed as expected.
You also need to run Particle: Library Install for Adafruit_mfGFX.
Furthermore I noticed some issue with the port as the library should be called Adafruit_ST7789 but is included as Arduino_ST7789.
You should replace all occurances of Arduino_ST7789 with Adafruit_ST7789.
After that you may also need to update some stuff about mySPISettings as this will throw some errors due to some changes in the Arduino compatibility layer for Particle.
For that you may want to replace
#include "application.h"
with
#include <Particle.h>
#include <Arduino.h>
Also defined(SPARK) wants to be changed to defined(PARTICLE).

You meean like this?
Almost
should be
#if defined(PARTICLE)
#include <Particle.h>
#include <Arduino.h>
#elif (ARDUINO >= 100)
#include "Arduino.h"
#include "Print.h"
#else
#include "WProgram.h"
#endif
(I also reordered it a bit to "favour" the Particle declarations )
This can be dropped as it's already included via Particle.h
This is how my project looks like (and builds successfully)
Thank you so much!
I have fixed the project and its compiling now.
But i get now output to the screen.
Can the wiring be wrong?
tft.screen | photon
CS -> D4
DC -> D3
RST -> D5
SCK -> A3
MOSI -> A5
I usually use all the A pins like given in the repo, but i need them for something else now.
Did you mean to write now output?
There is an alternative SPI interface on the Photon
But for that you'd need to modify the library to use SPI1 instead of SPI and re-direct RST, DC and CS too.
e.g.
MOSI -> D2
SCK -> D4
CS -> D5
DC -> D6
RST -> D7
Ideally the library would provide a constructor that also allows to pass in the SPI interface to use in order to keep it portable. But for the time being you'd just hard code SPI1
