Ultrasonic sensor 3.0 zero readout

#1

My mCore was not responding to ultrasonic sensor v 3.0. PWR LED is on, however distance is always 0 (like if the sensor was unplugged).

So I have tried to upload github example for library 3.0

examples/Me_UltrasonicSensor/TestUltrasonicSensor/TestUltrasonicSensor.ino (since I am new user I am not able to post the URL. Annoying restriction)

(oviously I have changed the port and tried different cables and (analog) ports). Reading is always zero. No sound from sensor is coming as well.

Looks similar to


however I can not find any soldering issues.

OK. Problem solved.

Since I am total dumbass who does not read the library readme (TLDR) I was running the example for orion board for mcore board. did not work.
