Datasheet

You can get the current click status register with lis.getClick() . Note that will return the raw 8-bit reg known as

LIS3DH_REG_CLICKSRC

Even though that register has 'axis' bits that theoretically tell you which axis the click is from, unless you bolt the

breakout to a huge thing like a table and thwack the table, any 'direct hits' to the sensor itself will register on any/all

axes because of the small scale.

Reading the 3 ADC pins

Finally, there are 3 extra 10-bit analog-digital-converter pins available. The details on these pins is scarce but we do

have code for reading data for them. This might be handy if you have a device without any ADC's

You can load the readadc demo sketch to start reading

While you can put 0-3.3V into the ADC pins, the valid reading range is only ~0.9V to 1.8V
