LCD

First, thanks for the code, very interesting project. 
I am trying to connect the Display, but it doesn't show anything (white screen) only. May I know what type ST7789 do you you use (if possible give me the link).

My connecttion is as follows
MOSI    11 //=SDA PIN
SCLK    12
CS   48   
DC   47  
RST  21  
BL   38

Thanks in advance from Indonesia
