 Read the CRCHost register. Compare this to the host-calculated CRC-32 to confirm

a successful upload.

 After the reset, write value 0x00 to the HostControl register, which clears the

HostUpload bit and places SENtral in Initialized State.

5.2 Initial Register Set-Up

After the initialization process is complete, it is necessary to configure a few of SENtral’s

registers before running in Normal Operation. These registers are given in Table 5-4.

Table 5-4: Registers for Initial Set-Up

Address

MagRate

0x55

Requested magnetometer output data rate

AccelRate

0x56

Requested accelerometer output data rate divided by 10

GyroRate

0x57

Requested gyroscope output data rate divided by 10

QRateDivisor

0x32

Along with GyroRate, establishes output data rate for

quaternion data.

AlgorithmControl

0x54

[0] 1 = StandbyEnable

0 = Disable Standby State

[1] RawDataEnable. 1 = Raw data provided in MX, MY,

MZ, AX, AY, AZ, GX, GY, & GZ.

0 = Scaled sensor data.

[2] HPRoutput. 1 = Heading, pitch, and roll output in QX,

QY, & QZ. QW = 0.0.

0 = Quaternion outputs.

EnableEvents

0x33

‘1’ indicates an interrupt to the host will be generated for

the event.
