hello

I am using DRV2605L, and I want to know the methods to enhance the strength of vibration.

and i want to perform DRV2605LEVM-CT through Haptic Control Console GUI, but i don't have USB2ANY Adapter, can i use EV2400 to replace USB2ANY Adapter.

Thanks a lot!

Hi Jesse,

The vibration strength can be increased by increasing the overdrive and rated voltage settings. The LRA will have a limitation on how much voltage can be applied without breaking the LRA.
You have to use the USB2ANY, I think. I am not familiar with this other adapter board. The USB2ANY has the correct type of MSP430 integrated as the micro-controller. This is why we are able to flash the firmware and use it with our software.

Thanks
what is the limitation range of overdrive voltage and rated voltage? Does them must be lower than VDD? is there any sugget value?
For LRA, In Equation 5, does the V(LRA-CL_RMS) equal rated voltage?
