Hi Scott,
Yes the DRV2667 will have no problem operating at 100 Hz or 50 Hz. If you would like to test this with the EVM, you can either have an external analog input or use Haptic Control Console to create a waveform of your desired frequency using the WaveSynthesizer by going to Tools -> RAM Manager -> DRV2667 and then selecting Advanced.
Hi Micah
Thank you for your help
If I can change the value of the register to get the output 100Hz or 50Hz
Which address is written to which value to get output 100Hz or 50Hz ?
Is there an easier way to change the frequency ? Can you show me it ?
thank you very much
Scott
Hi Scott,
The values for 0x03-0x09 will depend on what waveform you want to play. If you load multiple effects into RAM then you can select the waveform by changing this value. The EVM firmware can be downloaded here. The files waveform.c and waveform.h are used to set up the waveforms for the EVM.
