@teastain , Thanks for the info. I am at this for days, have been back and fort with supports@m5, this makes me feel terrible stupid for not able to get this HAT to work. I was expecting that by copying the example blocks, I would be able to get it to work. (very new to this.) There isn't any other options to select, except ENV under UNIT. Also, I have flip to micropython to cut/paste the code , then ran it on Thonny, it failed there, too; this also happen under Arduino (cut/paste) M5 example code for Arduino. I float the idea to the support@m5 that the HAT might be faulty but nothing from support@m5 on this defective HAT issue. I failed to mention that this is about the m5stickc plus. I hope the support@m5 will see this and come up with something to help me out. Or, anybody else out there that is able to help. Thanks again.

Ok, I am following with my post regarding the connection. First, I'd like to thank user 'ajb2k3' for trying to help. This is mainly user error, I saw the 'CONNECTING TO M5' flashing and the message just disappear' assuming that all was well and jump in to the mess. I wonder, what will it cost the system to have the 'CONNECTING TO M5' just hang in the loop, or issue a new message informing the users that he/she has not made a successful connection. I attribute it mainly to my carelessness. ASS U ME , always hurts.

@ajb2k3

Agree with learning to crawl before running. Will just concentrate on REPL. The tutorial has many examples- machine, network etc... but these are not what I like to learn now. I like more basic stuff, like how to get the buzzer to play musical tune if it's possible. I have a PIR HAT, I'd like it to sound musical tune without putting a SPK HAT (can't with PIR on). For now, I will just forget about the ENV3.

Ok, after further googling, I think I have to deal with pip, python3 and esptool in order to install Micropython on the Stick and also remeber that the Stick is not part of the laptop computer. Just like you mentioned earlier that the Micropython is part OS and BIOS. Wow! so many things have to go into this. How do I up vote your guys?

I downloaded the ' esp32-20220618-v1.19.1.bin ' and used Thonny to burn it, it wiped the flash before burning but after burning the Stick just wouldn't get up, I turned back to M5burner to get it back up. I don't know how to use esptool to wipe and burn. I seems like I was missing the Micropython or Python itself.

I am assuming  that M5burner is as good or better than burning  ' esp32-20220618-v1.19.1.bin '  on it. By using  ' esp32-20220618-v1.19.1.bin ' did  I miss out on some needed utilitie  that causes the Stick to sleep.

Dyslexia and ADD, sound like my normal. Do I have to install Micropython+Python3, as well as burning it on to the Stick?

I am drawn to this hobby because of many Youtube clips make it looked simple and I don't have any modern day programming experience so I am gravitating toward Uiflow and I was thinking I might learn some things or two about Controller/IoT plus Micropython. I just started reading m5stack.h from Git hub last night and it's looked intimidating and I didn't see any reference to sht30 chip,which I assume it is used in ENV3. Reading this m5stack.h file, how do I see the contents of these files? on Git

#include "utility/ANYFILES.h"

Have thought about learning Arduino along the way but example codes looked very intimidating. Well, if "tempC = sht30.cTemp - 1;
can calibrate the Stick then I will revisit Arduino. My basic understand of programming is limit to Function call/return. nothing about object, class, header files, include and define. Teastain, will you please point out where I can download example Sketch to calibrate the Stick. I just want to know how it can be done with changing input data without burning the calibrating data directly on to the sht30 chip.
 
Thanks both of you for coaching.

You sure have LOAD up there, wow! just those alone will probably take me years to read up, thanks for your advises. I have contacted support@m5 requested that they send me software/firmware to calibrate this Stick.

Personally, I am not up to the the job of calibrating. Casually thinking about the problem, it nearly impossible to calibrate it. If I use my thermostat to calibrate, it's only good for the first time, once. I notice, the env3 is fluctuating between 18f--33f, while the thermostat is set to around 67-68f With that, I don't have a acceptable target number to go by, only a wild constant but that won't do it. I might as well forget about this ENV3.

On micropython, what really confused me is to burn micropython on to the Stick, according to info from micropython.org ,It seems to me that there are two portions of Micronpython, here I am assuming again that is what happen with burning the Stick with the Uiflow. This isn't like anything I learnt years ago. Am I correct to assume that the burnt in portion, is like PC BIOS ?This is fun but way more complicated than just write Dbase II or COBOL. I will keep trying, at least it will keeps dementia at a distant. Just hope that it won't turn into a stroke!! Hey, since I am here how do I save blocks on flow.m5stack.com, click on the save icons either top or bottom left panels give me nothing, click on SaveAs, only option is PNG files. Another one, why do I need serial driver with M5 but not with Arduino, or I am just assuming that Arduino doesn't, or, because I already had the driver installed prior when burning Uiflow, then use Arduino after that. Oh, thank for differentiated the UNIT and HAT. Thanks.

Thanks much, now there is hope. Will you please give me advise , how should I go about tune this thing up, since it is block. I think I will have to do computation base on my thermometer output before sending it on to the screen, right? I programmed fifty years ago but will try to learn this new stuff. I used DOS 1.9 and Dbase III, since then I have played on/off with Linux, just resurrected old discard Window machines for friends and my grandkids. It's just a matter of burning a USB with Linux, boot from it, that's is it. So, at best I can do with Linux is cut/pastes. Well, thanks again. I will post once I get it to work,.

question are:-

What is the different btwn Unit and Hat on the left panel? Clicking the '+' symbol beneath either Unit or Hat gives me the same result of the Hats selections page.

Why is the ENV3 reading is way off, I attached my thermostat and the ENV3 output.

I was bitten badly using the Desktop IDE (had hard time connecting to flow.m5) not conscience of the missing HAT blocks in IDE, I just click on the '+' symbol under Unit on the left panel, picked ENV3 , went from there and got 'env3 unit maybe not connect' running the example blocks.

Resolved, the part that generated 'env3 unit maybe not connect' , I use the HAT (ENV) this time and don't get the error message. This, I still not sure that I blindly got it as I supposed to. Well, go on learning. Thanks.
