VL534CD example python from website does not work on Raspberry PI

Sensors Distance
1

I am running on a Raspberry pi. i2cdetect does not detect the sensor but i am sure the wiring is correct, and when I connect it to an arduino it works.

I tried running your Example1-ReadDistance.py program but it gives this error

Installing collected packages: sparkfun-qwiic

This is annoying to debug as the sensor i bough is a V:534LCD yet the sample code from your site references a different sensor name, and even the name it is referencing does not work… please help

It looks like there’s a workaround described @ the end of this thread https://github.com/sparkfun/Qwiic_VL53L1X_Py/issues/7

That thread only makes it clear that there are errors in the source code that have existed for 2 1/2 years. Hard to work on a board when the provided examples dont work. Here is my console – How about you respond quickly to this request and get the source code posted on your production website fixed asap

import sparkfun_qwiic_vl53l1x

cat Example1.py

import sparkfun_qwiic_vl53l1x

import time

print(“VL53L1X Qwiic Test\n”)

ToF = qwiic.QwiicVL53L1X()

if (ToF.sensor_init() == None): # Begin returns 0 on a good init

print(“Sensor online!\n”)

while True:

try:

ToF.start_ranging() # Write configuration bytes to in\

itiate measurement

time.sleep(.005)

distance = ToF.get_distance() # Get the result of the measurement from the sensor

time.sleep(.005)

ToF.stop_ranging()

distanceInches = distance / 25.4

distanceFeet = distanceInches / 12.0

print(“Distance(mm): %s Distance(ft): %s” % (distance, distanceFeet))
