has anyone used ST7789 2.4inch TFT display ?

[aliyesami]

I was using ILI9341 2.4inch TFT and its obsolete and replaced by ST7789 controller but the code iam getting from newheaven display is not working .
has anyone used this display and can please share the initialization code.
I am attaching my initialization code and the program code. its displaying text in jagged form and also displaying blue instead of yellow.
