White screen issue (with all example files)

[TriDEntApollO]

I uploaded the example file to my ESP32 dev board and the HCSrceen.cpp had an issue with the Color565() method (turned out new library changed the capital C to smaller case c but even after that and uploading the code the screen remains white.

P.S. The screen works fine normally without issue

Hi, tested the code myself and got the same issue and started to look into why and for me it was that with this setup
(From the example code)

//tft instance
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
HCScreen screen = HCScreen(tft); 

The constructor in HCScreent tried to use the tft, before I had set it up in my setup() function, so I removed
the following two lines in the constructor
https://github.com/GerLech/HCScreen/blob/master/HCScreen.cpp#L48
https://github.com/GerLech/HCScreen/blob/master/HCScreen.cpp#L62
and in the setup() function I called for init after I had the setup my tft like

 tft.initR(INITR_BLACKTAB);
 screen.init();

This made the code work for me.
