Starterware/DRV2605L: How to make 2 waveform in DRV2605L

Part Number: DRV2605L

Tool/software: Starterware

Dear

 I would like to make the below waveform to input it to LRA

  -  Click(Touch Home button) : 250Hz 1cycle(2Vrms) + 200Hz 2cycle (2Vrms) , Sinewave

  - Remove                   : 250Hz 1cycle(1Vrms) + 200Hz 2cycle (1Vrms) , Sinewave

 

Could  you let me know how to make it in DRV2605L ?

Thanks in advance

  • Hi Park,

    This is not possible with the DRV2605L. You can only play waveforms at a set frequency. The only way you could try to perform this functon is by changing the frequency via I2C mid-way through the first portion of the waveform. This would have to be done by playing an open-loop waveform and using one of the TRIG modes.
