hi guys
i was trying to simulate the HMC5883L magnetometer sensor in Proteus and after a hard time finding it i was able to make it work , at least i think , because there is no change in the position of the sensor i get a reading of 0 , is there is a way to simulate its motion to get any reading ?
the code :
#include //I2C Arduino Library
#include
LiquidCrystal lcd (4,5,6,7,8,9);
#define addr 0x0D //I2C Address for The HMC5883
void setup() {
lcd.begin(16,2);
Wire.begin();
Wire.beginTransmission(addr); //start talking
Wire.write(0x0B); // Tell the HMC5883 to Continuously Measure
Wire.write(0x01); // Set the Register
Wire.endTransmission();
Wire.beginTransmission(addr); //start talking
Wire.write(0x09); // Tell the HMC5883 to Continuously Measure
Wire.write(0x1D); // Set the Register
Wire.endTransmission();
}
void loop() {
int x, y, z; //triple axis data
//Tell the HMC what regist to begin writing data into
Wire.beginTransmission(addr);
Wire.write(0x00); //start with register 3.
Wire.endTransmission();
//Read the data.. 2 bytes for each axis.. 6 total bytes
Wire.requestFrom(addr, 6);
if (6 <= Wire.available()) {
x = Wire.read(); //MSB x
x |= Wire.read() << 8; //LSB x
z = Wire.read(); //MSB z
z |= Wire.read() << 8; //LSB z
y = Wire.read(); //MSB y
y |= Wire.read() << 8; //LSB y
}
// Show Values
lcd.setCursor(0,0);
lcd.print(x);
lcd.setCursor(0,1);
lcd.print(z);
delay(500);
}
