drawCompass()
Description
A helper function for displaying the compass on the TFT. Relies on Robot.beginTFT(). drawCompass() uses debugPrint(), which can't be used in the same sketch.
Mind where you draw text and other graphic elements when using drawCompass() so that you don;t overlap elements.
Syntax
Robot.drawCompass(degrees);
Parameters
degrees: int between 0 and 359. Typically it's determined by Robot.compassRead().
Returns
none
Examples
#include <ArduinoRobot.h>
int compassValue;
void setup(){
Robot.begin();
Robot.beginTFT();//Initialize the TFT module
}
void loop(){
compassValue=Robot.compassRead();
Robot.drawCompass(compassValue);//draw the compass
}
int compassValue;
void setup(){
Robot.begin();
Robot.beginTFT();//Initialize the TFT module
}
void loop(){
compassValue=Robot.compassRead();
Robot.drawCompass(compassValue);//draw the compass
}
