- Hi, I am working with LIS2DE12 accelerometer. Till now, I am able to read the raw data provided by the chip. Now, I have to detect free fall for the same. In the data sheet, I couldnt find any specific registers assigned for this purpose. The only thing I could find is that there are two interrupt pins available for the motion detect and free fall detect. But I dont know how to configure this interrupts. Can anyone provide me the steps for the configurations? How can I decide the threshold value for generating this free fall detect?? Thank you in advance!!!
