    It's great to see technology and nature coming together like this. I've wanted to experiment with automation ideas for my small balcony garden, and this challenge might be the perfect opportunity to start using my M5Stack gear finally. I’m looking forward to seeing what everyone creates!

    Hello guys

    some ideas for the next version of M5StamPLC:

    switchable 5 V on Grove ports switchable 5 V on extension port LED indicators for the relays LED indicators for the inputs

    Notes for 1.: the existing ICs can be used by connecting output (P3) of (U5 PI4IOE5V6408) to the enable (EN) of (U4 LPW5209AB5F) instead of having EN tied to SYS_5V.

    Notes for 2.: the existing ICs can be used by connecting output (P1_0) of (U4 AW9523B) to the enable (EN) of (U8 LPW5209AB5F) instead of having EN tied to PMU_5V.

    Thanks
    Felix

    That was painful but figured it out.
    Must be better ways but this works where lastWord will be the exact SMS message sent.

    log(receivedMsg); // Display the received message

    receivedMsg.trim(); // Remove any trailing or leading whitespace, including newlines // Find the last newline character or any other delimiter expected) int lastNewlineIndex = receivedMsg.lastIndexOf('"'); // Extract the substring after the last newline character String lastWord = receivedMsg.substring(lastNewlineIndex + 1); lastWord.replace("\n", ""); lastWord.replace("OK", ""); lastWord.replace("\r", ""); // Removes all carriage return characters

    Hello,

    I have this Module (SKU:M039-V11):

    https://docs.m5stack.com/en/module/Stepmotor Driver Module13.2 v1.1

    If I use in UiFlow2 the module "StepMotor Driver" it dosn't work.

    Where can I find the Uiflow1 Micropython Code for module.STEPMOTORDRIVER?

    I would like to translate it to UIFLOW2.

    Thank you.

    @papajon you may need RS485 adapter if M5Stick can't use wifi to access networked devices, overall M5Stick is esp32 with built in lcd and some more bits so in arduino/micropython its literally esp32

    I recently get a M5 Dial V1.1 and I have card with mifare 1k card encrypted with known key A/B and read data from block 1.
    I used to work with Arduino and rc522 and it works fine.
    Now I tried to migrate my project to M5 Dial and a had some problems on writing authentication keys on WS1850S and get feedback of authentication status.
    in UIFlow 2's RFID instruction didn't mention about the encryption things.

    在教程和Project Zone里面找过Felmue发过的帖子，上面有提及读写NFC数据但是没有提及使用密钥读取已经加密的卡片。在Ｂ度也没搜到WS1850S的资料（只有简化版资料表）。可以帮忙找一下写入KeyA，KeyB和验证密钥所需要写入的指令吗？
