    @teastain Just wondering how your answer, 'openess' [sic] helps to answer my question. Even if it were an actual word, which it's not 🤔. Care to elaborate?

    @marnix201 said in PPS 13.2 Module not working properly:

    Hi all,

    I ordered a couple of Module13.2 PPS (SKU:M137) modules for use with the M5Stack CoreS3 main units.
    Unfortunately I can't get it to work, when I upload a "Default" test code (Initialize the unit, set output to True and after that Set the current and voltage to desired levels) sometimes it works just one time, but most of the time the module does not respond, or it says: Module not found.

    I also tried scanning for I2C devices and I found out that the address is not present all the time, it fluctuates between present and not present, this does not happen with other I2C devices on the same bus, I of course use the standard address: 0x35 and i have a stable 24V on the DC-in connector (1A capable) and no load attached to the output.

    I tried many different controllers and many different PPS-modules with and without other devices on the bus, but unfortunately they all give the exact same results....

    I also tried flashing the firmware update from the official website because I hoped this would help increasing the communication stability of the PPS-module, but by doing this I bricked already 2 of my PPS-modules =( , after the update I cannot find them anymore while scanning the I2C bus for devices....

    The Link to the Firmware updater: [https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/products/module/M137 Module13.2-PPS/pps_upgrade_v1_esp32s3.exe](link url)

    Can someone please help me with this ?, and can my "bricked" devices still be fixed ? =(.....

    Thank you,
    Marnix.

    ( All of the above is tried using UIFlow 2 by the way.
    I also tried it using custom commands via the I2C module in UIFlow but I get the exact same results (sometimes it works but most of the time the PPS-module does not respond to commands)

    This is the result of scanning I2C devices with the PPS-Module attached:
    UIFlow2.0-I2Cscan.png

    It's all about the "53" which is 0x35 in HEX (The address of the PPS-module)
    You see that it's not constantly available and this is why the communication often doesn't work...

    Hello,
    I'm very new to UIFlow so this could just be a beginner learning but I'm running into some strange issues with UIFlow.

    I have the Ext-Encoder working but I'm unable to reliably reset the counter to 0. I'm not sure what all the related blocks do but I've tried a bunch of options using reset encoder rotary value and set rotary value to 0. It seems to occasionally choose a number which isn't 0 to reset to. This presents as the value "resetting" to a consistent random number when hitting a limit switch. Reset number has varied between resets - I can sometimes get the reset value to be 0 if I don't move the encoder during the first few seconds of program time but even that isn't consistent. The sensor is excellent outside of this issue. I'd prefer not to create some hacky workaround or rewrite in Arduino but I'm getting close.

    I couldn't for the life of me get a simple limit switch or button to work. Was messing around with ports, pins, etc and ended up just initializing the pin and using it at the pin level, which then worked without issue. Is there a secret I'm missing or does a simple limit switch not work when using the UIFlow gui as designed? Tried both the limit switch sensor module (U145) and the optical switch (U058) and neither worked.

    I'm not sure what info to post to help debug this, I could probably create a quick example that illustrates these issues, let me know if that would help.

    I'm using a core S3 and arc browser.

    Thanks in advance!

    应该是固件bug，有没有试过2.2.0
