Lirc0 not found on jetson / jetpack any versions

[hemsinghb]

Hi ,

Please enable lirc0, i.e. infrared pwm pin from any of 40pin header of jetson boards. this enables infrared wire less remote control functionality on jetson boards.

thanks, Hems.

Hi hemsinghb,

Are you using the devkit or custom board for Orin Nano?
What’s your Jetpack version in use?

Do you want to port lirc0 and control it through pwm on Orin Nano?
How do you connect them? (i.e. which pin are you using)

Hi, I’m very happy to see the reply. I wanted the facility on the Original Jetson Orin nano dev kit. (Presently what I am using) . Unfortunately, the port is not available as it is available on Raspberry Pi. So My request to you is to enable any pin to transmit out and also receive IR signal on any suitable pin of the 40 pin header.

your Question: Do you want to port lirc0 and control it through PWM on Orin Nano?
Ans: Yes, please. on rpi (sudo apt-get install lirc followed by $ ls /dev/lirc0 gives activation of lirc0), however, it is not so on jetson jetpack 6.0 or jetpack6.1 or any jetson version. So I kept my request forward to you, please.

thanks,
–Hems.

hi, once again for reference you are requested to see this website please: Easy Setup IR Remote Control Using LIRC for the Raspberry PI (RPi) - Updated Oct 2021 [Part 1] : 7 Steps - Instructables

Activating lirc on Jetson will help many of the users of Jetson and also solve many more automation problems with existing IR-based gadgets. presently, as of now no lirc port on Jetson we are forced to go for the esp8266/ esp32 board in addition.

For the devkit, you can refer to Unable to generate PWM with Nvidia Jetson AGX Orin Development Kit - #6 by KevinFFF to verify PWM from 40-pins expansion header.

Sorry that I’m not familiar with lirc package, which seems designed for RPi.
You may need to customize for the pins you used on Jetson.

From the link you shared, it needs only 3 pins (3.3V, GND, PWM output).
You can get those signals from 40-pins expansion header on Orin Nano devkit.
