Hi!
You may try to debug your I2C bus using i2c-tools
.
Get list of I2C busses - i2cdetect -l
:
i2c-1 i2c bcm2835 (i2c@7e804000) I2C adapter
Get list of devices on the bus 1 - i2cdetect -y 1
:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- 29 -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

You can see the device with address 0x29, which is the rangefinder.
Thank you for your reply. I manage to solve the problem. Since I'm new with ROS I wanted to ask how can I use the sensor with rviz? Thank you
Run rviz on your computer with pointing ROS_MASTER_URI
to your RPi's hostname; add /vl53l1x/range
topic visualization.
Some more info here: https://clover.coex.tech/en/rviz.html#start-rviz
I tried to use that but why it said that for frame [] fixed frame [map] does not exist
In ROS, in order to visualize the sensor data each sensor should declare its pose in space (most often relative to the robot's body), using a TF frame. Please, address the main TF documentation to learn details.
By default, the driver publishes an empty frame (header.frame_id = ""
), so you should configure it manually in the launch-file.
The simplest way to see something is to put any string you want there (e. g. rangefinder
) and set it as the rviz fixed frame name.
Hello, i have problem with the I2c in ubuntu. I'm using raspberry pi4 with ubuntu 20.04 and make connection for sensor using I2c in raspberry pi. then i got the error at the terminal said that "failed to open I2c bus 1" is there anyone know how to solve this problem. I really need help since I need to solve it urgently. Thank you
