How can I use multiple sensors of this type on the same raspberry pi? I can’t use Breakout Garden ( https://shop.pimoroni.com/products/breakout-garden-hat ) because I have to position them in a specific way. I read about the change-address.py script. Do I have to use that to change address? And how d…

i2c is a shared bus, you can have multiple devices as long as no two devices have the same address. That will happen if you connect two VL53L1X sensors to the one i2c bus that are at the factory settings. Too get around this most of the Breakout Garden breakouts have a jumper on the back to change …

I never used the change-address.py script ( https://github.com/pimoroni/vl53l1x-python/blob/master/examples/change-address.py ), mine was just an idea. Does this script change the address permanently or does it have to be run at every start? If it were final, I would have solved it. Although I don’t…

I assume its run once to change it. Then run it again if you want to change it back. If you run i2cdetect -y 1 and take note of its address. Then run the change-address.py on one sensor, change it, and reboot. Then run i2c detect -y 1 again. If it has the new address its a only have to run once d…

The error is likely because its looking for the sensor at its old address. You have to edit one or two lines in the PY file telling it the new address. For example in this line tof = VL53L1X.VL53L1X(i2c_bus=1, i2c_address=0x29) you have to change the 0x29 to the new address.

Hi, one question, on the VL53L1X O couldn’t find a jumper to change the I2C address. On the backside it’s only print on one address 0x29 (default). So is there really a jumper (one the BME680 theres is on alsp printed 2 I2C addresses). So, if I want to use 2 VL53L1X Tofs, (as I understand the mail …

Hi, did you have it up and running. I cascaded 2 ToFs and connected it as described above. Before I ran the change adress script. But I only see one I2C address 29 or 33. Cascaded I see only 29. For me it seems, Tov losses it new address after disconnecting. Both ToVFs are Pimoroni VL53L1x? thx P…

I wouldn’t hook them both up at the same time while running the change address script. Just hook the one you want to change up, change its address, then check to see if it changed. Then swap the other one in and see what address it has. It sounds like you may have changed the address on both of them…

What I have done on a couple of my setups is add a Proto Hat and some male headers for my i2c breakouts. Then use female to female jumper wires to connect them to the Proto Hat.
