Ok last night i found this code, and uploaded it to the arduino. Pins 11 and 9 are motor outputs, it works ok, still having problems with the joysticks. When i press R1,L1 on the controller this allows me too use the joysticks to control the speed of the motors, the problem is that i have to hold the joy sticks all the way down or the motors will spin about half speed. I have tried to fix this in the code but have not had any luck. here is the code!
#include <PS2X_lib.h>
PS2X ps2x;
//int Lp = 7;
//int Ln = 4;
//int Rp = 8;
//int Rn = 12;
int El = 11;
int Er = 9;
int right_speed = 0;
int left_speed = 0;
void setup () {
ps2x.config_gamepad(2,6,4,7, true, true);
//pinMode (Lp, OUTPUT);
//pinMode (Ln, OUTPUT);
//pinMode (Rp, OUTPUT);
//pinMode (Rn, OUTPUT);
pinMode (El, OUTPUT);
pinMode (Er, OUTPUT);
digitalWrite (El,LOW);
digitalWrite (Er,LOW);
Serial.begin(9600);
}
void loop () {
ps2x.read_gamepad();
left_speed = ps2x.Analog(PSS_LY);
right_speed = ps2x.Analog(PSS_RY);
left_speed = 255 - left_speed;
right_speed = 255 - right_speed;
left_speed = map(left_speed, 127, 255, -255, 255);
right_speed = map(right_speed, 127, 255, -255, 255);
if((left_speed>=-25) && (left_speed<=45)) {
left_speed = 0;
}
//WHAT SHOULD I PUT IN THE ELSE STATEMENT??
Serial.print("Left Joystick Value: ");
Serial.print(left_speed);
Serial.print("\t");
Serial.print("Right Joystick Value: ");
Serial.println(right_speed);
if(ps2x.Button(PSB_L1) && ps2x.Button(PSB_R1)) {
analogWrite(Er, right_speed);
analogWrite(El, left_speed);
}
else {
analogWrite(Er, 0);
analogWrite(El, 0);
}
}
