Setup and Operation with a DRV2604LEVM-CT
This section describes how to setup and operate the DRV2604LDGSEVM-M with either the
DRV2604LEVM-CT board. The "non-L" version of the EVM-CT boards can be used in place of the "L"
version but the firmware needs to be updated to the "L" version.
shows the connection of the
breakout board to the DRV2604LEVM-CT board.
Figure 3. DRV2604LDGSEVM-M Connection to DRV2604LEVM-CT
1. Connect the DRV2604LDGSEVM-M to the DRV2604LEVM-CT with IC test hook lead cables as shown
in
. If VIO header pin is not being used, it can be left floating. Connect a separate actuator to
the OUTP and OUTM headers of the DRV2604LDGSEVM-M.
2. Make sure that the DRV2604LEVM-CT has the jumpers connected properly as shown in
.
3. Connect the mini-USB cable to the USB connector on the DRV2604LEVM-CT board.
4. Connect the other end of the USB cable to an available USB port on a computer.
5. If the DRV2604LEVM-CT is powered correctly, the four colored LEDs will turn on, the four mode LEDs
will flash, and the LRA and ERM will perform auto-calibration, indicating the board has been
successfully initialized.
6. Next, press buttons B1, B2, B3, and B4 observe that there is a different vibration on each.
7. If the vibrations are felt on the separate actuator (coming off from the EVM-M), then the breakout board
is working properly.
