      @felmue I'm doing multi scans because I'm not sure how do make one and pass the results to both the Label and print functions.

      Yeh found out about the sleep mode, you have to hard reset the base plate to wake it up before running an i2C scan.
      I'm running 1.10.2 and found the issue is in the i2C setup function.

      addresses = i2c.scan()
      Is just a left over function of what I was testing earlier.

              Hello @ajb2k3

              thank you for putting together the guide. Unfortunately I cannot get it to work. I do not fully understand the following instructions from your guide.

              Now I have the basics after poking away at micropython I import machine and units._ID0

              import units
              from units import _ID
              ID_0 = unit.get(unit.ID, (21,22))
              

              Using Thonny and ...
              ... trying to import units._ID0 results in an error.
              ... where is _ID used?
              ... trying to run ID_0 = unit.get(unit.ID, (21,22)) still crashes my M5Core2.

              Thanks

                @felmue It will.
                You have to run the commands in that exact order or it will crash and restart!

                If you run help('modules') in Thonny you will find the module units/_ID this took me house to work out.

                _ID0 does not exist, the module is _ID

                  Hello @ajb2k3

                  thank you. I appreciate all your help. Unfortunately for some reason I cannot get it to work on my side. Whatever steps I execute before, every time I try to execute ID_0 = unit.get(unit.ID, (21,22)) my M5Core2 crashes.

                  Thanks

                    @felmue Sorry, you need to import unit
                    Then import units then from units import _ID

                    also the code is

                    import units
                    import unit
                    from units import _ID
                    ID_0 = unit.get(unit.ID, (21,22))
                    

                    however you can also use:

                    import units
                    import unit
                    from units import _ID
                    ATECC = unit.get(unit.ID, (21,22))
                    

                    I don't know why both unit and units (with an S) must be called but they both do.

                      Hello @ajb2k3

                      thank you again. I tried both your code sequences - still no luck. M5Core2 still reboots after the last command.

                      Which UIFlow firmware version is running on your M5Core2?

                      Thanks

                        @felmue ok, its been working all day and now crashing
                        1.10.2

                        OK if you make 1 single mistake, you to to disconnect and power down the Core2 to empty the memory

                          at this point I think whether the commands succeed or result in a crash depends on the amount of free memory.
                          With a freshly rebooted M5Core2 the following commands (sometimes) can be executed w/o crash.

                          >>> import unit
                          >>> ID_0 = unit.get(unit.ID, (21,22))
                          >>> print(ID_0.wakeup())
                          True
                          >>> print(ID_0.readConfigZone())
                          Traceback (most recent call last):
                            File "<stdin>", line 1, in <module>
                            File "units/_ID.py", line 186, in readConfigZone
                            File "units/_ID.py", line 363, in read
                            File "units/_ID.py", line 377, in read_output
                            File "units/_ID.py", line 161, in idle_mode
                            File "i2c_bus.py", line 100, in write_list
                          OSError: I2C bus error (110)
                          >>> print(ID_0.readConfigZone())
                          True
                          >>> print(ID_0.revisionNumber)
                          bytearray(b'\x00\x00`\x03')
                          

                          Note: The commands need to be executed manually one by one.
                          Note: I don't need the import units nor the from units import _ID commands.

                            Agreed, once the error occurs then memory gets filled requiring hard reset.
                            You didn’t need unit or the from? I will try again later.
                            I have spent all weekend writing up the atecc for my av2 book including logging the MP modules. I’ll try without those two line tonight.

                              The issue of found was that the basic unit functions are in the unit module with unit.ID being empty but the ATecc function are all in units._ID

                                @felmue try adding the following before defining ID_0

                                From esp import gc
                                gc.collect.

                                This should help clean up some memory.

                                Nope that was wrong. the min code I can get running is

                                import unit
                                import units
                                from units import _ID
                                import gc
                                ATECC = unit.get(unit.ID, (21,22))
                                gc.collect()
                                

                                Oh cool, I got import units._ID to work.

                                    thank you. I've tried to add the gc.collect() command. The result is still not 100% persistent. From time to time I still get a crash.

                                    Thanks

                                      @felmue thanks for letting me know. It’s been stable for the testing but I’m yet to move beyond. I tried looking at provisioning for vets and codes but my brain is not taking it in hence the low level MP stuff.

                                      I’m sure there will s an issue with MP but I don’t deal directly and not getting feedback from @m5stack or @IAMLIUBO
