Notes
Use this mode to control the DRV2604 using an external I2C Master. Press B1 or B2 to
choose between the ERM or LRA. Press B3 to choose the trigger type. (1 - Internal, 2 -
Ext. Edge, 3 - Ext. Level). Press B4 to trigger the waveform sequencer.
Run the auto-calibration. The new auto-calibration results are used for all board effects.
1 flash = successful, 3 flashes = error.
Run diagnostics. 1 flash = successful, 3 flashes = error. The status register bits [3:0]
are displayed on the mode LEDs [3:0] when complete.
External PWM - disconnect MSP430 PWM using JP1. Connect external PWM signal to
the "PWM" testpoint at the top of the board. Select actuator using buttons B2 and B3.
External PWM and Enable - disconnect MSP430 PWM using JP1. Connect external
PWM signal to the "PWM" testpoint at the top of the board. Connect an external enable
signal to the "EN" testpoint. Select actuator using buttons B2 and B3. Press B1 before
switching modes.
Analog Input - apply an external analog signal for AC coupling on the "Audio" jack.
Apply a DC coupled signal to the "PWM" testpoint.
Vary the auto-resonance OFF (open-loop) output frequency and see the change in
vibration force over frequency. Hold B3 or B4 for quick frequency adjustment. Compare
B2 (auto-resonance off) with B1 (auto-resonance on).
Life Test using RTP (2 seconds on, 1 second off) - life test repeats infinite times and
board must be powered down to stop. Increment / Decrement amplitude using B3 and
B4. Test new amplitude using B2. Choose actuator using buttons B1 and B2 in Mode 0
or Mode 1.
Life Test using RTP (Infinite Buzz) - board must be powered down to stop buzz.
Increment / Decrement amplitude using B3 and B4. Test new amplitude using B2
before beginning life test. Choose actuator using buttons B1 and B2 in Mode 0 or
Mode 1.
Life Test using PWM (2 seconds on, 1 second off) - life test repeats infinite times and
board must be powered down to stop. Increment / Decrement amplitude using B3 and
B4. Test new amplitude using B2. Choose actuator using buttons B1 and B2 in Mode 0
or Mode 1.
Recorder - use this mode to create a single amplitude pattern. Start by pressing the
record button (B1). Then use B2 to create the pattern by tapping the button. When
finished press the play back button (B3).
Life Test (RAM Mode) - Increment / Decrement amplitude using B3 and B4. B1 -
Start/Stop Infinite Buzz Life Test. B2 - Start/Stop 2s ON, 1s OFF life test. Choose
actuator using buttons B1 and B2 in Mode 0 or Mode 1.
Actuator Break-in - used to break in new actuators
About the Board - the value will appear on the mode LEDs in binary.
