Wii Camera Sensor

Posted: Tue Jan 14, 2014 3:56 pm

Code:

struct Dot1{
int x_Pos;
int y_Pos;
int size;
};

struct Dot2{
int x_Pos;
int y_Pos;
int size;
};

struct Dot3{
int x_Pos;
int y_Pos;
int size;
};

struct Dot4{
int x_Pos;
int y_Pos;
int size;
};

void init_Wii_Camera(void){

i2c_start();
i2c_write(0xB0); i2c_write(0x30); i2c_write(0x01);
i2c_stop();
delay_ms(100);

i2c_start();
i2c_write(0xB0);
i2c_write(0x00); i2c_write(0x00);
i2c_write(0x00); i2c_write(0x00);
i2c_write(0x00); i2c_write(0x00);
i2c_write(0x00); i2c_write(0x90);
i2c_stop();
delay_ms(100);

i2c_start();
i2c_write(0xB0);
i2c_write(0x07); i2c_write(0x00);i2c_write(0x41);
i2c_stop();
delay_ms(100);

i2c_start();
i2c_write(0xB0);
i2c_write(0x1A); i2c_write(0x40);i2c_write(0x00);
i2c_stop();
delay_ms(100);

i2c_start();
i2c_write(0xB0);
i2c_write(0x33); i2c_write(0x03);
i2c_stop();
delay_ms(100);

i2c_start();
i2c_write(0xB0); i2c_write(0x30); i2c_write(0x08);
i2c_stop();
delay_ms(100);
}

void Read_Wii_Camera(void){
i2c_start();
i2c_write(0xB0); // Device address
i2c_write(0x37); // Data to device
i2c_stop();
delay_us(25);

i2c_start(); // Restart
i2c_write(0xB1); // to change data direction
//Read First Dot
Dot1.x_Pos=i2c_read();
Dot1.y_Pos=i2c_read();
Dot1.size =i2c_read();
//Read Second Dot
Dot2.x_Pos=i2c_read();
Dot2.y_Pos=i2c_read();
Dot2.size =i2c_read();
//Read Third Dot
Dot3.x_Pos=i2c_read();
Dot3.y_Pos=i2c_read();
i2c_stop();
delay_us(380);
i2c_start(); // Restart
i2c_write(0xB1); // to change data direction
Dot3.size =i2c_read();
Dot4.x_Pos=i2c_read();
Dot4.y_Pos=i2c_read();
Dot4.size =i2c_read();
i2c_stop();
}

This will allow you to read 4 points of infrared light sources

X position 0 to 255
Y position 0 to 255
Intensity 0 to 255

The data will be stored in the structs above

It's not complete. You're not doing a NACK on the last i2c_read() before the i2c_stop() in two places in your program.
