Table 5 lists the modes available for design and testing.
Table 5. DRV2667EVM-CT Binary Modes
Mode Button Description Notes
Mode 0 B1 Memory store enabled GUI Mode – use this mode to trigger and store the sequencer set by a GUI. Store the
GUI Mode sequencer by first pressing B1 (the mode LEDs turn on). Then press either B2 or B3,
B2 Store/Play memory 1
LEDs: 00000 storing the sequencer values. Press B1 again to exit memory storage. B4 triggers the
active sequencer.
B3 Store/Play memory 2
B4 Trigger active sequencer
Mode 1 B1 Disable Effect Building
Dynamic white
B2 Play effect once
Waveform Modes 1–6 can be used to create a unique effect by adjusting the frequency,
Playback amplitude, duration, and envelope of a single waveform. Button B1 in each mode is a
B3 Infinite playback
LEDs: 00001 continuous buzz with the frequency set in mode 2 and the amplitude set in mode 3.
B4 Infinite playback with 1-s wait
Button 2 in each mode is the effect created using the frequency, amplitude, duration,
and envelope set by the respective modes. It is recommended to use an oscilloscope
Mode 2 B1 Continuous buzz
to measure the output when creating effects.
