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. #lis3dh #lis3dh-interrupt2016-06-30 12:48 AM
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
