=== Read and Write CTRL_REG1 (20h) ===
This register is used to enable/disable: accelerometer and XYZ axes (See 8.8 chapter). The default value at startup is:
<pre>root@igep00x0:~# ./spiexampleb2 -R 20
spi mode: 0
bits per word: 8
max speed: 1000000 Hz (1000 KHz)
Value from 20 is: 07
root@igep00x0:~# </pre>
It means that accelerometer was disabled and X, Y and Z axes was enabled. For example we can disable X axe typing:
<pre>root@igep00x0:~# ./spiexampleb2 -W 20 -V 06
spi mode: 0
bits per word: 8
max speed: 1000000 Hz (1000 KHz)
Register to write 20 with value 06
root@igep00x0:~# ./spiexampleb2 -R 20
spi mode: 0
bits per word: 8
max speed: 1000000 Hz (1000 KHz)
Value from 20 is: 06
