Part Number:DRV2605L
Hello
I use DRV2605L to drive ERM.
DRV2605L was powered directly by Li-ion battery, so the DRV2605L is always on when battery has enough power.
1. Finish the Auto-level calibration process, MCU store the auto-calibration results in MCU memory.
2. when the system start up, the MCU will initial DRV2605L, rewite the auto-calibration inputs parameters and the results to DRV2605L, and do a vibration action.
The ERM sometimes has no vibration when system start up. ===> what's wrong with it? how to solve this problem?
3. on the other hand, If let DRV2605L to do auto-calibration everytime when the system start up, the ERM can has vibration everytime.
My question:
1. Does DRV2605L need to do auto-calibration everytime when system start up??
