Hi,
I am using nRF52805 with LIS2DW.
LIS2DW is connected to nRF52805 with general GPIO, not I2C port.
I am emulating GPIO to I2C protocol.
SDA and SCL pin is pull-up to 100K resistors.
After initializing LIS2DW, no need to use I2C bus.
But, in this case, some current is consumed thru pull-up resister.
I want to reduce the current consumption below 10uA when nRF52832 is in sleep state.
To reduce the leakage current thru pull-up resister, I find current is lower than output mode.
But, in this state, LIS2DW can not generate INT1 interrupt.
I re-config the SDA and SCL to output mode, LIS2DW is still not working properly, no generating INT1 signal.
- How can I reduce the leakage current thru pull-up resistors?
- Why LIS2DW can not work after SDA and SCL pin re-configuration?
Thank you in advanced
Paul
What is problem?
