It works just great.

Just curious to know whether did I miss this being documented somewhere?

naiffat,

Try this...

i2c_start();
i2c_write(currAddress);
i2c_write(0x00);
i2c_write(0xA0);
i2c_stop();

i2c_start();
i2c_write(currAddress);
i2c_write(0x00);
i2c_write(0xAA);
i2c_stop();

i2c_start();
i2c_write(currAddress);
i2c_write(0x00);
i2c_write(0xA5);
i2c_stop();

i2c_start();
i2c_write(currAddress);
i2c_write(0x00);
i2c_write(newAddress);
i2c_stop()

Best Regards,

I2C Sensor - Change address

I have successfully used the I2C line sensor with the PICDEM 2 Plus board. The performance is very good but my only feedback is that should be an eight sensors version instead of the present 5. I am thinking of using two sensor boards. So I have been trying to change the sensors' default I2C address from 0x50 to 0X58. However, the change does not seems to happen. Am I missing something here?

i2c_start();
i2c_write(0x50);
i2c_write(0xA0);
i2c_write(0xAA);
i2c_write(0xA5);

i2c_write(0x58);

i2c_stop();
