BMA253 Single tap

[mgchoi]

Hi, BOSCH

Use the current BMA253
I would like to use the function to wake up the MCU when an interrupt occurs using Single Tap.

Is this possible or what Resister should I use?

Hi,

Thanks for your inquiry.

BMA253 is not available for new designs. Please switch to BMA400. BMA400 has built-in auto wake-up and auto low-power interrupt feature.

Please see the attached PDF files for more information.

Thanks.

Hi, BOSCH

I set it up in the way you sent me during the test with DD, but there is no interrupt.

What kind of setting is needed for this part?

Hi,

Please increase the bandwidth to 1KHz instead of 125Hz as shown in the technical document. Then you should be able to see the single-tap interrupt signal on INT1 pin.

Thanks.

Interrupt does not occur even if set to 1KHz.
