For whom it may be of interest ....

I've ported the VL53L0X code from C++ to MMbasic (to my best knowledge, of course). The code is able to handle multiple sensors and is also able to be loaded as library into a PicoMite under MMbasic. The code is tested on a RP2350A and doing fine so far.
In the zip-file there is a file for
- the library code (can also be included 1:1 in the main code if needed)
- a main program to test it (uses a LCD display)
- a .txt file with some documentation

Comments are welcome, there is certainly much room for improvement

and I apologise for my programming style already upfront. It' not very elegant, but it seems to work.

VL53L0X.zip

maybe someone can use it ...

Regards,
Gerald

Sure, if you do not want control over the sensor you can use the default settings and get away with this very simple code. This is one of the charming features of the VL53LX0. I'd liked to do some experiments to see what one can do with the little beast ...

Matherp wrote it converted from GBasic.
The VL53LX0 is accurate to 10 mm up to 1 M, it's more for gesture control but good for object avoiding robots.

it's a small pcb that could be hidden in a walking stick... ultrasonic is okish, use one port on/off quick and it resonates 40khz then make port input
and it gets echo back.
used to use it for object avoid robots, preferred VL53LX0 for particular application.
blind walking stick but surely someone's done that .. commercially?
glad more VL53LX0 code posted

mmb i2c is underrated.. imho
you can do loads like port expander (for 2 stepper motors), ssd oled and VL53LX0
same time easy. thanks
