Hi
I have a Jetson TX1 board.
and I want to use one of the GPIO Header.
I have STM32 blue pill microcontroller
and in code, I set one of the pins to get HIGH and LOW in 5 seconds
I want to connect the pin on the STM32 with a jumper wire to the jetson and in the jetson with Python, check if the GPIO pin that connects to the STM32 pin is HIGH or LOW.
how can I do that?

There are examples you can follow

Hi, Thank you for your response 🌸🖐
is there no problem connecting the 3.3V jumper wire to jetson?
I'm afraid to burn the board...
Does not want a resistor in the way of the jumper wire?

You should put a resistor
