Hi
I am currently working on the simple sketch (it is not my , I am using some of the "Button test" code ).
Basicaly it is the simple menu with submenu. When you press button "1" you go to submenu and here is the problem I can not go back to main menu.
I am a real beginner so I asume there are meny errors in the code , and if anyone wishes to help me sorting this out I would be greatfull.
I am using DUE with 4,3 TFT and CTE shield and It took me 5 weeks to get everything to work (UTFT and UTouch).
#include <UTFT.h>
#include <UTouch.h>// Declare which fonts we will be using
extern uint8_t BigFont[];
UTFT myGLCD(ITDB43,25,26,27,28); // Remember to change the model parameter to suit your display module!
UTouch myTouch( 6, 5, 32, 3, 2);int x, y;
char stCurrent[20]="";
int stCurrentLen=0;
char stLast[20]="";/*************************
