Check program for LIS3DH bug fixed rev.
I fixed bugs in my library LIS3DH and updated it as Rev.7. This is a check program for LIS3DH lib.
Followings are PC console output data.

In addition, you can see reg. contents.

Here is meaning of data.
<Setting condition> STATUS_AUX=0xff -> new data are avairable but all data are over-run condition OUT_ADC1_L=0x00, OUT_ADC1_H=0x00 OUT_ADC2_L=0x00, OUT_ADC2_H=0x00 OUT_ADC3_L=0x00, OUT_ADC3_H=0x00 -> all ADC data are Zero INT_COUNTER_REG=0x00 -> ? WHO_AM_I=0x33 -> I'm LIS3DH TEMP_CFG_REG=0x00 -> ADC: disabled, Temperature sensor (T): disabled CTRL_REG1=0x47 -> Data rate selection: 50Hz, Low power mode: disabled, XYZ axes: all enabled CTRL_REG2=0x00 -> High pass filter mode selection: normal, Filtered data selection: internal filter bypassed High pass filter: bypassed CTRL_REG3=0x00 -> All kinds of interrupt: disabled CTRL_REG4=0x08 -> Block data update:continuos update, Big/little endian data selection: Data LSB/lower address Full scale selection. default value: +/-2G, High resolution output mode: disabled CTRL_REG5=0x00 -> FIFO disable CTRL_REG6=0x00 -> ?
