DS18B20
Posted: Wed Feb 15, 2017 1:37 pm
Greetings,
I am experiencing two problems.
1. I loaded the 1-wire example under ow.select on this page:
https://nodemcu.readthedocs.io/en/master/en/modules/ow/
I do have an init.lua that calls the example. The problem is that I can't get it to stop.
Things I have done:
a. Re-flashed the ESP. Not sure this actually worked. Should this remove installed files too?
b. Attempted to Format. No obvious effect.
c. Attempted to Upload and Reload the files (init.lua and DS18B20-Example) without success.
d. Disconnected the sensors even though I didn't expect this to make any difference.
Any hints on this?
2. Even though I have three DS19B20s connected there is no evidence more than one is addressed.
I assumed the example might actually work for three sensors but that is not obvious. Any hints?
I haven't been able to attack item 2 yet since I am still stuck on item 1.
Thanks!
Best regards,
Fred
