what j1010 gpio should i use for steering, speed, pololu multiplexer enable slave jetracer
Hi there,
And welcome Here…
Just follow the wiki on it and test it.
Step 1: Download the pinmux document according to the SoM you are using. Here we choose the Jetson Orin NX/ Nano document
Step 2: Find the GPIO label (under Customer Usage column) corresponding to the Module Pin Name that we got before. For example, for GPIO12, it is GPIO3_PN.01 and here we refer to PN.01
Step 3: Enter the terminal of the Jetson device and execute this command
sudo sucat /sys/kernel/debug/gpio
Step 4: Find the GPIO number corresponding to the GPIO label that we got before
THE rest is HERE…
If you get stuck , come back and let us know.
