The I
2
C group box allows external I
2
C device to be controlled using one of the DLPC900 I
2
C interfaces.
For example, if an LED driver requires I
2
C communications to enable the LEDs, then a command can
be sent to the LED driver using this interface. When using the I
2
C interfaces, first configure the I
2
C port
using the commands within the
I2C Settings
and then perform data transfers using the commands
within the
I2C Read/Write
.
