hello all
I bought a sparkfun redboard qwiic and a garmin lidar v4. I managed to connect the redboard to the macbook which is detected by arduino ide. I downloaded the sparkfun library for the lidar, I connected the sensor via qwiic and uploaded an example sketch but I can’t see anything from the monitor, it’s empty. How can I check that the sensor is connected correctly?
tried also “I2c scanner” skecth but it keeps scanning and no device is found
Try closing the other Arduino window; also that qwiic cable is pretty long which can create too high of resistance (in some cases); do you have a shorter one you can try?
I would also recommend removing the double-adapter thing going to the laptop’s usb and trying just a simple usb-micro to usb-A cable
Thanks for the reply
I tried on the Macbook with a new direct cable, a shorter Qwiic cable, closing the window, but the problem is still there.
If I unplug the qwiic cable the program says “Device did not acknowledge! Freezing”, so I suppose the sensor is detected.
Tried also on a PC but I have the same problem, nothing appears on monitor, but If I unplug the qwiic cable the program says “Device did not acknowledge! Freezing”
no suggestions? I can’t find documentation on other cases similar to mine. Maybe the sensor is not working? I’m thinking of sending it back…
maybe the voltage is wrong? i simply plugged the garmin lidar v4 into the redboard, assuming it was already right
Other sketches I’m trying work so I assume there’s something wrong with sensor
When I received I have connected the sensor directly to the board assuming the voltage was already correct
A user on a forum said:
Hi. Redboard is 5V however lidar I/O is 3.3V. Probably you burned the unit.
Can it be true?
