2.4" TFT LCD TOUCH SHIELD inverted

Using Arduino Displays
1

I have met some problem about this LCD touch screen, It was inverted coordination when I touch x left it shown in x right or y left it shown in y right. So what I need to change this code to correct way of using.please help me.
Thank you.

The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

If you get errors when compiling please copy them from the IDE using the "Copy error messages" button and paste the clipboard here in code tags

if you want to change the rotation of the screen you can use

tft.setRotation(x);

with a value 'x' of 0 - 3, as long as both are inverted you should be able to get it the working the way you want.

If it is just about the 'touch-screen' you can modify these :

#define TS_MINX 125
#define TS_MINY 85
#define TS_MAXX 965
#define TS_MAXY 905

It is advised to keep all your #define together, and to keep all your #include grouped together in your sketch
