compile error

Projects Programming

I am just getting back into Arduino after a few years. I have been trying to get a sketch compiled but getting an error message. The sketches I am tring to get going are the example sketches with the Adafruit ST_7735 library.

Every time I try to compile and up load I get an error saying HEIGHT = height and WIDTH = width error amongst others: See below
Anything I can do to get around this?

I think i need the sketch to tell you what is wrong.

Example sketch attached.
I have downloaded the latest Adafruit ST7735 librarywith same issue

Hi,

should your sketch use upper case WIDTH and HEIGHT if that's how its set in the Lib?

  tft.fillRect(tft.width()/2 -x/2, tft.height()/2 -x/2 , x, x, color1);

Have you updated Adafruit GFX Libary?
WIDTH and HEIGHT have been changed from const int16_t to int16_t. (github)
