Kenji Arai / Mbed 2 deprecated Check_new_LIS3DH_lib

Check program for LIS3DH bug fixed rev.

Dependencies:   LIS3DH mbed

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.

003855,new,[m/s2],-0.0588,+0.0686,+9.3555,[mg],    -9,   +11,  +956
003856,new,[m/s2],-0.0686,+0.0883,+9.3163,[mg],   -11,    +8,  +953
003857,new,[m/s2],-0.0981,+0.1275,+9.3752,[mg],    -9,   +13,  +953
003858,new,[m/s2],-0.0981,+0.0294,+9.3457,[mg],   -13,   +10,  +953

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
-> ?
 REFERENCE=0x00
-> Reference value for Interrupt generation=0
 STATUS_REG=0xff
-> new data are avairable but all data are over-run condition
 OUT_X_L=0xc0, OUT_X_H=0xff
-> 0xffc0 -> -64/16 -> -4 
 OUT_Y_L=0x10, OUT_Y_H=0x00
-> 0x0010 -> 16/16 -> 1
 OUT_Z_L=0x60, OUT_Z_H=0x3b
-> 0x3b60 -> 15200/16 ->950
 FIFO_CTRL_REG=0x00
-> FIFO mode selection: bypassed
 FIFO_SRC_REG=0x20
-> FIFO: empty
 INT1_CFG=0x00, INT1_SOURCE=0x00, INT1_THS=0x00, INT1_DURATION=0x00
-> Interrupt related reg's are not used
 CLICK_CFG=0x00, CLICK_SRC=0x00, CLICK_THS=0x00
-> Click action: not used
 TIME_LIMIT=0x00, TIME_LATENCY=0x00, TIME_WINDOW=0x00
-> Click related reg's are nit used
