Hi,I am designing a PCB board and use LIS2DH12/LIS3DH to wake up the processor. I will use I2C mode (CS pin should be connected to high) and SA0 pad connected to voltage supply (vdd) to get the device address as 0011001b. I see CS is at input high im...

I would like to wake up the processor from the deep sleep mode with the LIS2DW12 wakeup event. After the interrupt signal is generated from the INT1 pin, the processor will be waked up. However, it needs more than 1 second to power down LIS2DW12. Dur...

Dear Eleon, thank you so much for your professional reply. Does it mean that INT2 pin also should be connected to the MCU even I only use INT1 pin generated interrupt to wake up the MCU? May thanks.Tang
