      The ATECC is only accessible currently if you use Arduino or IDF but that doesn't stop the Core2 AWS being used with with AWS in fact I badly rote a book and published it on amazon and also have a guide here on using the Core2 AWS with UIFLOW.

        @ajb2k3 Thank you for your reply, but in UIFlow I can add it like a unit, in port I select custom (SDA/TX:21,SCL/RX:22), with this the DEMO1 in the UNIT ID works ok. In the Demo2 it crashes and it restarts.

        In UiFlow these are the available blocks for the ID unit (ATECC608B):
        WAKE UP:
        wake up

        READ:
        get info
        read config zone
        serial number
        revision number
        confi lock status
        data otp lock status
        slot0 lock status
        public key 64 bytes
        signature
        random min, max
        config zone
        key config
        slot config

        Write:
        generate public key
        write config zone
        lock config
        create new key pair
        lock data and OTP
        lock data slot0
        create signature data
        veify signature message
        sha256
        update random 32 bytes

        The problem is that I can not find more information about how to use these blocks.

          Sorry, I wasn't aware there were blocks for the ATECC

            @ajb2k3 Thank you for validating it, now the question is where could I find the documents that explain how to use this blocks to connect to aws iot core, instead of downloading the certificates from amazon console.

                @ajb2k3 Thank you, I found your book at amazon store, but in the description it doesn't say anything regarding how to use the ATECC608B with UiFlow. I have done examples subscribing my edukit to aws iot core, but I have downloaded the certificates directly from AWS, the question is how to use ATECC608B with uiflow. Do you have a book that I could buy with this topic?
                Regards

                  Ah no, I'm actually working on adding that to V2 of the book at the moment following your request.

                      Just a little update but no matter what I try, as soon as I try to access the I2C bus with the ATECC608, I get a kernel panic and restart.

                        Hello guys

                        I did some tests with the AWS bottom:

                        • When I stack the AWS bottom to an M5Core2 (using @gabrielgc75 trick with the ID unit and custom pins 21/22) I get a crash - something about I2C master not being initialized.
                        • However when I stack the AWS bottom to an M5Stack Basic (again using an ID unit but this time with default Port A) it works and I can access the ATECC608.

                        Thanks

                          @ajb2k3 It's super buggy. I tried getting this ATECC608 chip working with Arduino code and had very inconsistent results, kernel panics and crashes. The only way I've seen it run consistently is by running the RTOS code in the AWS edukit tutorials.

                              Interesting, It seams that the I2C master bus is not being initialised.

                                OK getting somewhere, every time you get a guru or kernel panic you need to hard shut down the core two for 5 seconds or the bug remains in memory.

                                    from m5stack_ui import *
                                    from uiflow import *
                                    import i2c_bus
                                    import machine
                                    i2c = machine.I2C(scl=machine.Pin(22), sda=machine.Pin(21), freq=133000)
                                    
                                    screen = M5Screen()
                                    screen.clean_screen()
                                    screen.set_screen_bg_color(0xFFFFFF)
                                    
                                    label0 = M5Label('label0', x=15, y=43, color=0x000, font=FONT_MONT_14, parent=None)
                                    
                                    print('Scan i2c bus...')
                                    addresses = i2c.scan()
                                    print(i2c.scan())
                                    label0.set_text(str(i2c.scan()))
                                    

                                    So the code get run out of order and crashes the i2c bus.

                                      Hello @ajb2k3

                                      are you doing multiple i2c.scan() calls on purpose? When I try that I only get an empty list. However doing only one scan works for me.

                                      I went through older M5Core2 UIFlow firmware versions and all of them crash on me when using the ID unit with custom values for I2C (e.g. 21, 22) in order to access the ATECC608 in the AWS bottom. And UIFlow firmware 1.7.5 doesn't support the ID unit.

                                      BTW: The ATECC608B has a sleep mode and when it is in that mode it will not show up during an I2C scan.

                                      Thanks

                                        @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.
