Introduce the necessary basic knowledge related to the IAM20680 gyroscope.

1. Basic information of gyroscope

We can know that IMA20680 is a six-axis sensor, which not only integrates a gyroscope (GYRO), but also a gravity sensor (Accel)code>) is integrated in it, and the transmission method is divided into two types, one is realized by SPI, and the other is mainly realized by I2C.We mainly implement it by mounting it on the I2C bus. The specific mounting on that bus needs to be confirmed with the hardware.

IAM gyroscope basic configuration:
Since the bus we mount is I2C, we must know that the chip corresponds to i2ccode>Address is: 0x68 or 0x69depending on
