How to Setup IMU
ADIS16470 is a complete inertial system that includes a tri axis gyroscope and a tri axis accelerometer.
The output interface supported by ADIS16470 is SPI (Serial Peripheral Interface). To connect ADIS16470 to Orin AGX we must convert SPI to USB. For that we have used a SPI to USB converter: USB-IIS. USB-IIS is a USB to Serial/I2C/SPI converter, simple, small, and easy to use. You do not need any extra library like libusb or libftdi. Need to remove Power Link (indicated by red arrow in below image)
Very simple schematic is here.J1 is the USB-ISS pin and J3 is the 2mm pin headers on the ADIS16470 breakout board.
| J1 Connector of USB-IIS | J3 Connector of ADIS16470 |
|---|---|
| Pin Name of J1 | Pin Number of J1 |
| GND | 1 |
| CS | 2 |
| MOSI | 3 |
| SCLK | 4 |
| MISO | 5 |
| 3.3V | 6 |
Connect both the modules as mentioned in above table.
