IMU Data

IMU Request Packet

Name Header Serial Number
Bytes 1 4
Type uint8_t uint32_t
Description 0x5A First request should be 0, otherwise the last one

IMU Response Packet

The IMU response packet contains multiple IMU packets, and each IMU packet contains multiple IMU segments.

Name Header State Size IMU Packets Checksum
Bytes 1 1 2 ... 1
Type uint8_t uint8_t uint16_t - uint8_t
Description 0x5B 0 is success, others are failed Content size IMU packets Checksum, XOR of all content bytes

IMU Packet

The IMU packet is an array of IMU datas.

Name Serial Number Timestamp Count IMU Datas
Bytes 4 4 1 ...
Type uint32_t uint32_t uint8_t -
Description Serial number IMU basic timestamp The number of IMU datas IMU datas

IMU Segment

Name Offset Frame ID Accelerometer Temperature Gyroscope
Bytes 2 2 6 2 6
Type int16_t uint16_t int16_t * 3 int16_t int16_t * 3
Description The timestamp offset Image frame ID Accel x,y,z values IMU temperature Gyro x,y,z values
  • Formula for converting the accel & gyro values to real ones: real = data * range / 0x10000 .
    • accel default range is 8 g, gyro default range is 1000 deg/s.
  • Formula for converting the temperature to real value: real = data / ratio + offset .
    • default ratio is 326.8, default offset is 25℃.
