2.3 ROM Library Mode

Access the ROM library effects by holding the + button until the mode LEDs flash and the colored LEDs flash ONCE.

Once in Library Mode the DRV2625 loaded ROM effects can be accessed in sequential order. For example, with all Mode LEDs off, B1 is waveform 1, B2 is waveform 2, and so on. Then when Mode LED M0 is on, B1 is waveform 5, B2 is waveform 6, and so on.

The equations for calculating the Mode and Button of an effect are:

Mode = RoundDown( [Effect No.] / 4 )

Button = ([Effect No.] – 1) % 4 + 1

% - modulo operator

To change between ERM and LRA:

  1. Select mode 31 (11111'b) using the + or – buttons.
    • B1 – Press to select ERM
    • B2 – Press to select LRA
  2. Then use the ROM effects as described above.
