DRV2605L: Length in time of the individual effects in the Waveform Library (#1-123)

Robert Havey
Prodigy 10 points
Part Number: DRV2605L

I am working on code to repeat the effects in the waveform library a fixed number of times and I need to understand how long each effect is for timing purposes.

In addition, it is not clear from the data sheet if a waveform playback is interrupted when a new "GO" command is issued. In other words, if I submit three "GO" commands in rapid succession, will the DRV2506 buffer these and play all three in sequence?

Thanks,

    Hi, Robert,

    Welcome to E2E and thank you for your interest in our products!

    Regarding the duration of the waveform, it actually depends of the effect that you select. For examples, a buzz effect requires more time than a click effect. This parameter unfortunately cannot be modified since these are predefined waveforms.

    In case of the "GO" command, this command will be set high until the effect finishes. If the GO bit is clear, the effect is interrupted. So, in order to set three effects consecutively, you may use the waveform sequencer as mentioned in section 8.3.5.2.1 Waveform Sequencer ( http://www.ti.com/lit/ds/symlink/drv2605l.pdf#page=16 ). In that way, you may run up to eight effects sequentially without need to monitor the GO bit and set it again when another effect is required.

    I hope this helps you. Please let me know if you have additional questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.
