vl53l0x question

Postby doctorlu » Fri Mar 10, 2017 6:58 am

Dear all,
I have a question about this laser ranging module. I use the code provided in the deck driver and give it a try. However, the ranging distance could only attain 1.2m or so, but I recall that this module could achieve as maximum as 2m ranging distance. May I ask if any specific regs of this module is not properly configured, so it can only result like this. What is the result after you guys have tested? Thanks

What we have seen as well is that it starts to get problems at around 1.2-1.5m. I think it is already configured for long distance measurements but it might be worth digging it to it to be really sure.

Oh yes, so this is not only from my observation.
Have you guys decided to find out why it happens?

My qualified guess is that the 2m distance is just in perfect conditions (over specified). I will put a ticket for it on github and hopefully someone will investigate it.
