LIS3DHTR interrupt pins

Hello guys,

I'm planing to use LIS3DHTR accelerometer in my next project. There is one thing (for the moment :-)) that is bothering me:

The default state of the INT1 and INT2 pins is not explicitly indicated within a datasheet (at least I could not find it). I'm curious to know what is default state of the INT1/INT2 pins and what is the state of those pins when the interrupt occurs?

Is this parameter (the state during the interrupt) configurable through I2C/SPI interface or there is just one default value?

Thanks in advance for your time and effort.

Sincerely,

Bojan.

Hello Bojan,

For interrupt configuration please refer to application note AN3308

http://www.st.com/content/st_com/en/products/mems-and-sensors/accelerometers/lis3dh.html

.

The default state of INT1 and INT2 pins is Low, when the interrupt occurs the pin goes High.

This parameter can be configured in CTRL_REG6 (bit 1 – H_LACTIVE).

Best regards

Miroslav
