@ajb2k3 Thank you so much! this is very helpful.
Could I also ask you to point me in a direction for the calibration formula or a small description of the theory behind calibrating it ? in my head I just feel like chopping 3 degrees off the reading would almost suffice, but Im sure there is a more eloquent method. Ultimately if I can figure it out, sleeping code will be needed for longer run times in terms of battery longevity. This seemingly also would help a bit with accurate temps.
Thanks!
@ajb2k3 this is great info!
I did start to understand the 0x56 addresse and 0x44 I think it is.. it seems like the addresses were the same in the technical manuals, but maybe that has no bearing on what you are saying ?
Im guessing the wire. commands Im seeing would be for the non hat version ?
Ill start looking for the difference in the pins and maybe be able to learn something again!
Again, Im a super newb and I appreciate the help.
I originally found this thread because my envIII hat temperature reading just cant be true. it seems a bit high and sort of climbs at time and peaks around 29 degrees. I suspect its the working temperature of the M5stick. screen heat I guess?
I know Im posting on an old thread, but the information for these things are hard to come by.
Im a newb, but sort of know what Im looking at with this code.
But Im unable to get this running on my M5stickCplus with ENVIII
even with the help for ENVIII in the code the // comments I cant get this working. I get the screen blink every 30 seconds, which I dialed down to ten seconds, and it blinks no readings, all at 0.00
What am I missing here? I also couldnt find M5_env.h and used m5stack_ENV.h from the install libraries, assuming they are the same ?
Thanks for any help. Especially thanks to the OP for his code here, looks promising, helping me learn a lot.
I have a brand new M5stickCplus, I feel like the screen is broken somehow.
I have feint lines on the screen that run vertical or lengthwise depending how you think about it. The seem to be part of the last screen or code I put on them. Like a ghost of the last code I burn onto it. Its odd.
Now only after letting it sit for a day or so, do the lines disappear once turned on again.
What is making these ghost lines appear and disappear ?
Thanks
