Protol format

Active Output Format

• The data is sent in hexadecimal not ASCII。

• Each data is transmitted in sequence by low byte and high byte, and the two are combined into a signed short type of data. For example, for data DATA1, DATA1L is the low byte and DATA1H is the high byte. The conversion method is as follows: Suppose DATA1 is the actual data, DATA1H is its high-byte part, DATA1L is its low-byte part,

Then: DATA1=(short)((short)DATA1H<<8|DATA1L). It must be noted here that DATA1H needs to be coerced into a signed short type of data before shifting, and the data type of DATA1 is also a signed short type, so that negative numbers can be represented.

Bit	NAME	FUNCTION
15:0	GYROCALITHR[15:0]	Set the gyroscope inactivity threshold: Gyro static threshold=GYROCALITHR[15:0]/1000(°/s)
Example: Setting the Gyro Rest Threshold to 0.05°/s FFAA 61 32 00 When the angular velocity change is less than 0.05°/s and lasts for the time of "GYROCALTIME", the sensor recognizes it as stationary and automatically resets the angular velocity less than 0.05°/s to zero The setting rule of the static threshold of the gyroscope can be determined by reading the value of the "WERROR" register. The general setting rule is: GYROCALITHR=WERROR*1.2, unit: °/s This register needs to be used in conjunction with the GYROCALTIME register
