VL53L1X distance sensor - file not found

anilthota · March 8, 2021, 6:28pm

Hello,

I have successfully tested the distance sensor(VL53L1X breakout board) when there was no SD card. After the SD is installed, distance_sensor gave error (see the attached image) e:\vl53l1x file does not exist. I copied the file as main still gave the same error. The same is repeating even with SD is removed. Please help.

Thank you,
Anil

You need to add a vl53l1x.py file to the sd card…

openmv/openmv/blob/master/scripts/libraries/vl53l1x.py

import pyb

VL51L1X_DEFAULT_CONFIGURATION = bytes([
0x00, # 0x2d : set bit 2 and 5 to 1 for fast plus mode (1MHz I2C), else don't touch */
0x00, # 0x2e : bit 0 if I2C pulled up at 1.8V, else set bit 0 to 1 (pull up at AVDD) */

Thank you for the quick reply. I did exactly what you have suggested before posting but did not work. In hindsight, that was because of my mistake in sensor connections. Also, I have VL6180X. Is this currently supported?

Thank you,

We do not have a driver for that. But, if you look at our vl53 source code it should not be hard to make the driver for that one.
