DRV2605L-Q1: Not getting Haptic feedback: DRV2605L-Q1

Hi,

i have been working to generate Haptic feedback using DRV2605l-Q1, but not able to get the feedback. i have attached my code written according to the instructions provided in the device datasheet.

Please check it once and let me know what need to be done to get the haptic feedback. waiting for your swift support, now the project is in critical stage, please take it on priority.

Thanks,

Sumit.
