Hi, I have an old 4DPi-24-HAT screen (https://www.4dsystems.com.au/product/4DPi_24_HAT/) and wonder if the 40-way GPIO header on TX2 works the same as that on Raspberry PI?
I haven’t looked at the RPi one, but it is very likely to be quite different even in cases where some pins have the same layout.
Thanks for the reply. I checked the pin definitions. They seem to be compatible.
For RPi: Page5 on https://www.4dsystems.com.au/productpages/4DPi-24-HAT/downloads/4DPi-24-HAT_datasheet_R_1_15.pdf
For TX2: https://www.jetsonhacks.com/nvidia-jetson-tx2-j21-header-pinout/
Any suggestions on finding proper drivers for a quick test?
Keep in mind that the GPIO number itself differs. You would have to adjust for this. Also, you’d want to verify if the RPi is using 3.3V or 1.8V I/O.
I am aware that RPi tends to have some convenience drivers for GPIO. The Jetsons have all GPIO drivers in place, but the convenience packages in user space which an RPi has do not exist on Jetsons (those libraries are specific to the RPi). I’m not sure what you’d have to do to adapt to that, I’ve not worked on the RPi. You might mention what you want to accomplish in terms of what software you want to give access to a GPIO pin since it is hard to work without details.
