how to get DFR0669 single click coordinates
Sami.Kankaanpää 2024-08-27 08:28:33 127 Views1 Replies I am using Arduino MEGA2560 and DFR0669 touch screen.
I have studied every example in the library but with my poor programming skills I have not found a way to get the X and Y coordinates of a single click gesture. Or any other means of reading the coordinates with the Touch library.
Should I use the UI or the Touch?
I have found out how to recognize an SCLICK gesture with the UI library but I haven't found any way to get the coordinates.
Could anyone please help me with an example line on this matter?
void loop()
{
//getGestures()：Recognize gestures
DFRobot_UI:: eGesture_t gesture = ui.getGestures();
switch (gesture) {
//single click
case ui.SCLICK : {
// here I need to find a code to read the coordinates
} break;
case ui.NONE: {
return;
}
}
}
In the sample code for DFR0669, the touch function is handled by DFRobot_Touch_GT911, which inherits from the DFRobot_Touch class.
While in the DFRobot_Touch class, the sPoints_t structure hastwo member variables x,y. It should be the coordinates you need to find.
This structure is in public and you can access it from outside of the DFRobot_Touch. Inside this class, sPoints_t instantiates _point, which means you can try to call this structure from the touch in the .ino program.
I added the following two lines to .ino and it compiles fine, which proves my point. However, I don't have DFR0669 in hand to test it, and also, you need to put these two lines into loop()
int x = touch._point.x;
int y = touch._point.y;
