2 Getting Started
The DRV2605LEVM-MD demonstrates how the DRV2605L device can be used in applications that require
multiple haptic drivers (same slave addresses) to be setup independently but be played simultaneously.
The board integrates the TCA9548A I
2
C switch to control which I
2
C lines of the possible eight DRV2605L
drivers are connected to the master input I
2
C bus. The switch has the ability to select any combination of
channels to be connected to the master input I
2
C bus.
The board also integrates the MSP430F5510 device with USB interface capabilities and bootstrap loading
(BSL) functionality. The USB interfacing provides the user flexibility in controlling the DRV2605L device
without having to modify the firmware. The BSL functionality simplifies the firmware updating process
without the additional hardware and the use of Code Composer Studio™ software.
The board receives power in two ways. For applications that require two or less active DRV2605L devices
device at the same time, the board can be powered through a USB port. For applications that require
more than two drivers, the use of the external power supply terminals with a current rating of 1.6 A is
recommended. Manual selection of USB power or external power can be set using the jumper headers
MSP and DRV. When powered up, button 1 and button 2 (B1, B2) can be used to demonstrate the
functionality of the DRV2605L device. See
Section 3 for a detailed description of the demonstration
application program.
