Hello
Has anyone tried setting up High-Precision AD/DA Board work with Jetson Orin Nano Dev Kit 8GB ? Else can you recommend an AD for Jetson Orin nano dev kit please?
My use case is analog to digital conversion.
I see Jetson nano software, not orin. First try using jetson nano code errors and exists at try to ADC.ADS1256_init():
ID Read failed
Thank you for your help !
Hi,
Could you please mention AD/DA board is connected to which tegra interface/signals.
Hello @Sheetal.G I’m on Jetpack 6, I am using RPi.GPIO library and I cannot find /gpio : cannot ls /sys/class/gpio . Is it something else in Jetpack 6?

Hi,
gpio sysfs is deprecated now. Please use gpiod_tools instead.
sudo apt update
sudo apt-get install gpiod
Also please help with the info which interface (like I2C1 / SPI) AD/DA board is connected.
