Jetson GPIO Pin Write
Writes a value of a trigger condition to a GPIO pin.
Overview
Writes to GPIO pins on Jetson devices.
Inputs & Outputs
- Inputs : 1, Media Format : Any
- Outputs : 1, Media Format: Same as Input
- Output Metadata : None
Properties
| Property | Value |
|---|---|
gpio_pin_name | Linux exported GPIO pin names. Multiple, comma separated values are allowed. Examples of pin names are e.g. PY.00, PZ.01 |
trigger | Trigger Condition whose value is to be written to the chosen GPIO pin. |
mode | Whether to write trigger values continously on each frame or only on changes. |
PIN Names
This node refers to pins using their kernel-assigned names, e.g. PQ.01, PAA.16, etc.
AIMobile
AIMobile Jetson Xavier NX (NCX1), Orin Nano and NX (NCON, NCOX)
For the AI Mobile Orin devices, there two exposed DIO pin that can be configured in OUT direction on the xcon devices (Orin Nano 4/8GB, Orin NX 8/16GB). The pin mapping is below.
| Pin Identifier | GPIO Pin Name (use in Node) |
|---|---|
| GPIO1 (see image below). | PQ.05 |
| GPIO2 (see image below). | PQ.06 |
GPIO1 and GPIO2 are the two GPIO pins available on AIMobile devices.
AIMobile Orin Multi-IO Devices (PSOX, PSON)
| PIN Identifier (see image below) | GPIO Pin Name | Notes |
|---|---|---|
| DI1 | PZ.03 | Input Only |
| DI2 | PZ.04 | Input Only |
| DI3 | PZ.05 | Input Only |
| DI4 | PZ.06 | Input Only |
| DO1 | PY.00 | Output Only |
| DO2 | PY.01 | Output Only |
| DO3 | PY.02 | Output Only |
