      I have a problem with the NCIR-2 temp sensor not being available in the Unit selection window of UIFlow2. I decided to switch to the NCIR hat and forego the high temp alert capability of the NCIR-2 and low and behold, the hat was missing from the add hat section too.
      These are current products for sale in the M5 store. Wasn't the NCIR-2 introduced over two years ago? I think there would have been ample time to integrate them into the latest UIFlow.

        Hello @wmatkins

        re: NCIR hat : I think it should work by adding the NCIR unit but with a custom I2C setting, e.g. SCL=26 and SDA=0.

        Note: I do not have the NCIR hat or unit so I cannot test this myself.

        Thanks

          Hello @sorphin

          I can confirm that in M5Dial UIFlow2.0.3 firmware the blocks for the built-in RFID reader are not working and throw an error. However, as a workaround, I used the blocks of a virtual RFID unit (and modified I2C SCL and SDA pins) to successfully read RFID cards with the internal RFID reader. See PlayZone M5Dial_RFID_UIFlow2.0.3 example.

          Thanks

            @felmue Thanks for confirming as well Felix. I did find that I could make it work in a round about way as well (using rfid.RFID (no parenthesis)).. but one shouldn't have to do that :/

              I am programming using UiFlow 2.0 on my M5Stack Stick C Plus 2.

              I have 3 issues currently:

              • 1
                When I burn UiFlow 2.0 using M5Burner, the tool shows esptool being used, which reports the file size being ~20KB.
                This is very fast (less than a minute).

                When I use UiFlow 2.0's web interface to upload my program (~20KB) via USB in the web terminal, however, It is very very slow (~2-3 minutes).

                The issue also happens when I upload a file from the web terminal.

              • 2
                When I upload a file or program, it results in an empty (0 Bytes) file! (most of the time), I burned the old Alpha-29 version of UIFlow 2 on my device using M5Burner, and this problem is fixed

              • 3
                Half of the time, when I run the program, the colors are inverted (instead of RGB, it's BGR, literally)

                I would like to use the touchscreen on the M5Dial. But the block M5.Touch.getCount() does not work in a while loop! It only works in the main loop. So the touchscreen is hardly usable in Micropython. I have not been able to realize the waiting for a touch.

                  Hello @Peter

                  the trick is to add an M5.update() statement (using an Execute mpy Code block) inside the while loop.
                  See UIFlow2 Project Zone example: M5Dial_Touch_Get_Count_In_While_Loop_UIFlow2.0.4

                  Thanks

                    @felmue Thanks Felix, it works:)
                    I didn't look to the Project Zone. I'll do it now.

                        Is there any way to port projects from UiFlow 1 to UiFlow 2 (.m5f to .m5f2)?

                        I've been searching in the forum but didn't find any message about it.

                        I've to start all my development from zero or there is any way to port projects from one system to the another?

                        I've several developments for M5StickC.

                        If it is possible, I think it must be put more visible how to do it. If it's not possible, it must be warning in some place to be visible too.

                        Thanks.

                          Since update 2.0.9, the buttons on my M5Stack Stick C Plus 2 have been tangled and unusable

                          The button A and power button (aka button C) are now unresponsive. Their respective callbacks do not get triggered at all.
                          The button B will trigger the callback for button A!

                          Here is my test program:
                          uiflow2_block_1720288367871.png

                            except (Exception, KeyboardInterrupt) as e:
                              try:

                          All was working well in UiFlow 2.0.8 yesterday, please fix this so I can continue to use it.

                            I also tried some other methods since, none of them had the desired effect:

                            Method 2 - Pin buttons

                            • This method works only with mode High (pull_low=False), with or without pull
                            • It is incredibly slow to respond (about 1 second)

                            Edit:
                            Oh, right, I almost forgot.
                            There is no such thing as the following in the machine.Pin method:

                            p.irq().flags()
                            

                            I don't know if it is because of the micropython port you guys use or if it is the esp32-pico-v3-02's fault, but I think there is something missing there...

                              @CAT-the-Tech I tried running your code and found that it works well.

                                @lbuque Really?
                                Which method did you use? (1, 2, or 3)
                                What device are you using?

                                Thanks

                                  Since version 2.1.0, The Pin Buttons method (method 2) does not work AT ALL anymore

                                        @lbuque Weird...
                                        Can you show me the StickC Plus 2's code you used?
                                        Are you sure your core3 AND StickC Plus 2 are at the latest version? (2.1.0 as of yesterday) (You can see this when it boots, in the terminal)

                                            DIN base does not require software support, it can be used directly.
