GPIO Description
The Jetson.GPIO library of the Jetson series motherboards allows developers to interact with external hardware devices through the 40-pin GPIO pins.
1. GPIO numbering
Jetson.GPIO library supports two common numbering modes: BOARD and BCM mode
Note: The tutorial only demonstrates GPIO.BOARD mode
| Mode | Numbering method |
|---|---|
| GPIO.BOARD | Numbering based on physical pins (1-40) |
| GPIO.BCM | GPIO logical numbering based on Broadcom chips (directly corresponding to the GPIO channels on the hardware chip) |
2. GPIO pins
2.1. GPIO.BOARD mode
One-to-one correspondence between BOARD mode pins and 40Pin pins on the motherboard:
2.2. GPIO.BCM mode
One-to-one correspondence between BCM mode pins and 40Pin pins on the motherboard:
3. Other pins
