SLAVE_ADDRESS

#define SLAVE_ADDRESS   0x48

This example shows how to configure the I2C module as a master for multi byte transmission in interrupt driven mode. The address of the slave module is set in this example.

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• I2C peripheral
• GPIO Port peripheral (for I2C pins)
• SCL2
• SDA

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• USCI_B0_VECTOR.
