2.2 Description of the Modes
The modes above were created to showcase various benefits of the DRV2603. See the description of
each mode below for more details.
2.2.1 Mode 0 – Ramp and Fade Waveforms
Mode 0 is ramp effects which demonstrate transitional effect capabilities of both LRAs and ERMs.
2.2.2 Mode 1 – Buzz and Alerts
Mode 1 demonstrates an LRA with auto-resonance on, an LRA with auto-resonance off, and an ERM.
Compare the difference in strength between the LRA with and without auto-resonance.
