I’m a developer with no experience in electronics (even searching is complicated…), and I want to use a custom IR camera on the Jetson AGX Developper Kit.
The IR camera is a component of a complete system. It is plugged on a motherboard with a 4 pins micro-JST cable. I want to unplug the camera so I can connect it directly to the Jetson to make a new customizable autonomous system.
The only information I have so far is:
- the name of the 4 pins on the motherboard: “5V-TX3-RX3-GND”
- a documentation which mentions using UART (“115200 baud rate, 8 data bits, 1 Stop bit”) to send a request message to the camera so I receive an fixed length answer with several fixed length fields among which the temperature map which I want to process.
Is it possible to do something with so few details?
I see the Jetson AGX has UART connectors on:
- the 40 pins extension header, which has UART1_TX (pin #8) and UART1_RX (pin #10) beside a 5V and a GND pin.
- the micro-USB plug beside the extension header (“for UART console”)
And I’ve seen this tutorial using Python with pyserial to use the UART pins of a Jetson nano: https://www.jetsonhacks.com/2019/10/10/jetson-nano-uart/
So there is hope maybe?
