Hi, I am using Jetson Xavier and raspberry pi
-
Raspberry pi send signal to Jetson Xavier. They are connected by cable.
-
Xavier take signal
-
This is my code. I type any other to import
if GPIO(25 or 22 or whatever) == 1:
print(“Triggering OK”)
else:
print(“Waiting signal”) -
Raspberry pi signal is
GPIO.LOW
timesleep(2)
GPIO.HIGH
timesleep(2)
GPIO.LOW -
And I want to be “waiting signal” → “triggering ok” → “waiting signal”
but it doesn’t. the signal is so instability. like “waiting signal” → “triggering ok” → “waiting signal” → “triggering ok” → “waiting signal” → “triggering ok” → “waiting signal” again and again. not stop.
I check voltage, ohm and current about Raspberry pi by using multimeter
voltage = 12v(when the signal come in), ohm, almost 0(when the signal come in, ohm is 0. usually 20) , current 0
I think jetson is something error.
what’s wrong is this on Jetson ??
