      I'm using UIFlow2 on Microsoft Edge and when I try to create a variable with the name of an object that already exists, I get the conflict information and even if I correct it, when I exit the variable creation window, UIFlow2 crashes and I have to reload the page to continue.

            did you mean a built-in magnetometer?

                  why don't you try a simple laptop/desktop?

                    Could you unlock from UIFlow 2 the capability to code in micropython…

                      I am looking for all of the lcd drawing tools that were available in uiflow1.0. I was making some interactive graphics and I was drawing lines or rectangles in a loop and doing that in uiflow2.0 requires you to first drag out 100 lines in the ui builder which just is too slow. Here are the bloacks I am looking for in uiflow 2.0. How can I do something similar in uiflow 2.0 Screenshot 2025-02-18 235307.png

                        Hello,

                        I have some difficulties to burn UIFLOW on new devices

                        For ATom lite it seems to work but i get ERROR The device type is unknown! on device manager.
                        I dont know if it can acces to the wifi. i tried several time to unregister and burn it again, reinstall M5 burner, but it doesn't help.

                        It can't connect to my M5 stamp C3, maybe there is a way to make a factory reset on them?

                        The previous Atom and Stick set up in february still worked well, and appears with green dot on device manager. when i try to burn it now i get the "unknown type" error and red dot.

                        it looks like i am not able anymore to have the same atom running when i burn them today.

                        Did i forgot something ?

                        Thank you very much,

                        Charles

                              When Will LVGL be integrated in UIFlow 2 ? I don't see a progress there for many months. The new devices such as Tab5 are useless without LVGL. Programming with UiFlow 2.0 and printing simple lines and squares look very old school.

                                Thanks for sharing the UiFlow 2.0 resources! I appreciate having a dedicated space for bugs, how-tos, and feature requests. Does anyone have tips on avoiding common firmware burning errors, especially with account binding? Also curious if there’s a timeline for the full API docs release. Looking forward to seeing how this evolves!

                                    I used UIFlow2 to devleop a simple UI demo, and I monitor the free memory with gc.mem_free(). I found the free memory reduced continiously though I called gc.collect() every loop. Finally, the UI can not update again, but the loop still was running.

                                      I tested more UI design. And I found that the memory leak only happens when I use image component and switch images frequently. Is that a UIFlow2.3.3 bug or my design is incorrect?

                                        Today, I updated the UIFlow to V2.3.4, and burned V2.3.4 firmware as well. Then I tested that image component again with M5GFX in UIFlow 2.3.4. But the issue still exists. After I switch two JPG pics with one image component for sometime, the memory will reduced continiously. Finally, the system will break out. And I try to use gc.collect() after every drawImage(), but it's not useful.
                                        Here is my design and python code:
                                        import os, sys, io, gc
                                        import M5
                                        from M5 import *

                                        ImageSwitchFlag = None

                                        def GcCollectAndPrint():
                                        global ImageSwitchFlag
                                        gc.collect()
                                        print(gc.mem_free())
                                        pass

                                        def btnA_wasClicked_event(state):
                                        global ImageSwitchFlag
                                        if ImageSwitchFlag == 0:
                                        M5.Lcd.drawImage("/flash/res/img/RotaryBGBacklight.jpg", 0, 0)
                                        GcCollectAndPrint()
                                        ImageSwitchFlag = 1
                                        elif ImageSwitchFlag == 1:

                                        GcCollectAndPrint()
                                        ImageSwitchFlag = 0

                                        def setup():
                                        global ImageSwitchFlag

                                        ImageSwitchFlag = 0

                                        def loop():
