    You can continue developing on the M5Stack Core2 reliably. The key is to bypass UIFlow entirely and use MicroPython directly through Thonny or VS Code.

    @Apex574R Does the Userdemo firmware running normally?

    I found a design issue (or corner cut) in the HW design phase that dramatically reduce the versatilty of this extremely nice board. On the Audio signal path from Input LINE/MIC 3.5mm TRS, there is a circuit that feed the microphone signal from the IN/OUT TRRS Jack. I get the logic behind this decision but the implementation affect the frequency response on the LIN1 path. The result? You cannot use the board to process analog stereo signals as RIN1 frequency response is flat at the HW input and LIN1 isn't! My solution would be to add an electronic switch (maybe a TS12A12511) on the MIC_MONO_IN between R9-C14 node and FSUSB42MUX to cut that path entirely. The control signal can be tied with LIN_MIC_PU_EN from the STM32G030; when the Headphones Electret is energised, the path to LIN1 would be restored. A better solution would be to make the control separate and use one of the available GPIOs on STM32G030 and a separate I2C command on 0x33 address. It is so simple... This will eliminate the need to physically remove C9 in order to get a flat response for BOTH Line inputs thus having a STEREO Audio Module. See this also: My findings about this I even asked M5 AI for this issue and it was funny because it didn't knew about this issue: If you're seeing different frequency response between left and right, the most likely cause is: One channel's HPF is enabled while the other is not (rolls off low frequencies) Different PGA gain settings between channels The two physical mic inputs may have different input impedance/coupling characteristics Cheers, Adrian

    My M5Stack CoreS3 suddenly stopped working. Here is the current situation: Screen is completely black When I press the power button, it turns on for a moment but immediately shuts off USB is recognized for just a moment when power button is held, then disappears RST button long press does not enter download mode Separating Core from Body and waiting several minutes did not help Serial monitor shows nothing Has anyone experienced this and recovered it? Any suggestions would be appreciated.

    HaM5dsp is a high-performance real-time DSP Firmware built for amateur radio operators, designed to run on affordable and portable M5Stack Core2 hardware. [image: 1781669913897-ham5dspspalsh.jpg] [image: 1781669934174-maindarktheme.jpg] [image: 1781669961709-main-screen-overload-resized.jpg] [image: 1781669983133-mainmilitarytheme.jpg] HaM5dsp is designed for HF operators who want a standalone, high-performance DSP audio processor, independent of their radio equipment. Whether you’re switching between rigs or operating in the field, HaM5dsp delivers a consistent audio experience with predictable results — every time. Alternatives exists. Expensive. HaM5dsp is more affordable. And it even features a MP3Player for rainy days! There is so packed with features that a post here will be too long to read so, if you want to read more about, you can find it on my personal blog: HaM5dsp-section

    Hello @sbeeker UIFlow2 doesn't use API keys. (Only UIFlow1 used them.) Are you sure you installed UIFlow2 firmware onto your M5Stack device? Use M5Burner from here to install UIFlow2 firmware (as an example for M5Core2) then use your browser to go to UIFlow2. [image: 1781279688656-m5burner_uiflow2.0_m5core2.png] Thanks Felix

    Приветствую! Прошу помочь с подключением Cardputera-ADV к UIFlow 2.0. Создал проект, но не получается загрузить его для проверки на устройство. В UIFlow справа внизу отображаются только две кнопки кнопки "Run Once" и "Run Always". WebTerminal выдаёт ошибку: NotFoundError: Failed to execute 'requestPort' on 'Serial' : No port selected by the user. P.S. Драйверы установил, через m5Burner установил на устройство UIFlow для ADV.
