How do I change the slave address on my optical sensor part?
The Si1132, Si1141, Si1142, Si1143, Si1145, Si1146, and Si1147 have a command that allows you to change the i2c address of the device. This change in address is only temporary and will be cleared back to the default address upon a reset.
The Si1133 and Si1153 have a hardware pin that causes the device to initialize with an alternate slave address. The pin that causes this change is Pin 6 on both devices. When this pin is pulled down to GND, the device will use its alternate slave address. On the Si1153, the use of the LED driver on this pin is lost when using its alternate slave address.
