Part Number: DRV2605L Other Parts Discussed in Thread: DRV2605 When I saw the datasheet about Waveform sequencer,
it described that when I set the bit 7 (Wait bit) for Waveform Sequencer, WAV_FRM_SEQ[6:0] bit will be interpreted as a wait time. It means…
in RTP mode(and all other modes) the LRA will be driven at the frequency that is found during the auto calibration routine. and then using the RTP_INPUT[7:0] register field you can control the 'envelope' of the waveform. We don't have a tool…
Part Number: DRV2605L Hi Team,
We would like to control LRA with open loop mode, the rated voltage of the LRA is 1.5Vrms.
I would like to know how to setting parameter to meet rated voltage?
there are some differences in the register maps for these devices.
the registers related to the LRA calibration should be the same between devices (0x16-0x1A) however there are some differences.
your firmware may be writing to some incorrect…
Thank you for your kindly response.
I just want to double check the process to set LRA with DRV2605L.
Before starting to drive LRA for my research project, I need to do auto-calibration. Then, do I need to do it again whenever I start driving motor? …
What frequency are you driving in PWM mode? The max is 250kHz
You can set the open loop period in register 0x20 using this formula: LRA open-loop period (µs) = OL_LRA_PERIOD[6:0] × 98.46 µs
0x22 reports the measured resonance period…
Part Number: DRV2605L-Q1 Dear TI engineer
This is Johnson.
Here are the questions about DRV2605-Q1
(1) If DRV2605-Q1 support Real time playback, what's the input frequency in I2C? And what tools I can use to tune the waveforms?
The DRV2605L EVM requires a USB2ANY adapter to connect to the GUI. https://www.ti.com/product/USB2ANY/part-details/USB2ANY?utm_source=google&utm_medium=cpc&utm_campaign=ocb-tistore-promo-asc_opn_en-cpc-storeic-google-wwe&utm_content=Device&ds_k…
we do not have a tool for generating the waveforms for RTP mode. the waveforms will need to be generated manually.
You should create a sequence of writes that contain a amplitude values written to RTP_INPUT[7:0] register 0x02, and delays
