Hi

Below is the captured waveform of MBR3116 CS0 pin, which is connected to a sensor.

It shows a frequency-changing waveform. Is that coz MBR3 uses PRS clock?

Could the clock frequency be decreased by modifying some setting parameters of MBR3?

Thanks.

Hi GrWa_2302706​,

Yes, MBR3 uses PRS for sense clock. The parameters are set by SmartSense and can not be modified.

Hi Bragadeesh

Is MBR3 always in SmartSense even though automatic threshold is disabled ?

Another question is that why automatic threshold should be disabled when median filter is used.

Thanks.

Hi GrWa_2302706​,

Yes MBR3 device operates only in SmartSense mode.

The RAM available in MBR3 devices is limited therefore enabling median filter and auto threshold will cause RAM overflow.

We recommend you to evaluate PSoC 4S  devices (4000S , 4100S ,4100S plus) that has latest gen CapSense and is programmable.
