DRV2625 Haptics BoosterPack™ Plug-In Module
The user can select the effects with the help of the UP and DOWN buttons. Once one of these buttons is
pressed, the MSP430FR2512 configures the DRV2625 to prepare the selected effect. When the user
presses the GO button, the MSP430FR2512 writes ‘1’ to the GO bit of the DRV2625 (Register Address
0x0C; Bit 0).This particular bit fires the selected waveform.
For more details about the DRV2625 Registers Map, please consult the DRV2625 data sheet .
5.2 Auto-Calibration Mode
It is always recommended to use the auto-calibration mode when the DRV2625 is powered on. This mode
allows the DRV2625 determining the best parameters to handle the connected LRA load.
In order to access to this mode, the user must press once the MODE button after the device is powered
on. The word “AUTCAL” will be shown in the LCD of the LaunchPad when the auto-calibration mode is
selected.
The GO button will start the auto-calibration mode. If the LRA is connected and fixed in the PCB correctly,
it will be activated few seconds. During this time, the DRV2625 will configure the appropriate LRA
frequency and the rest of the parameters to control the LRA load.
During this mode, the UP and DOWN buttons do not have any effect.
5.3 Off Mode
This mode places the DRV2625 in standby state. Any attempt to enable the device with the UP, DOWN,
and GO buttons does not have any effect in the DRV2625. The LCD in the LaunchPad board will show the
word “OFF” when this mode is selected.
The device will be enabled again until the MODE button is pressed again. If the MODE button is pressed
once, the Demo mode will be selected. If it is pressed one more time, the device is configured in Auto-
Calibration mode.
