    • RE: M5Paper crashing on EPD.Clear, or SPIFFs.begin

      Hello @Hamnet

      correct, to continue to use M5EPD you either need to revert to Arduino 1.8 IDE (which worked for you in the past). Or you can try to comment out the lines mentioned in GT911.cpp and use Arduino IDE 2.x. The latter I tried myself and worked for me.

      Thanks

    • RE: (ESPHome) Missing header file for Atom Lite?

      Hello @Dieter_P

      Note: I do not have a lot of experience with esphome. I just installed it on my Linux system and created a project. Unfortunately I cannot recreate the error you are getting. That said, I noticed that your project doesn't seem to use the latest version of FastLED. Maybe forcing it to download the latest (3.5.0) might help? Below are the first few lines of the mytest.yaml file that I was using:

      esphome:
        name: mytest
        libraries:
          - FastLED @3.5.0
      
      esp32:
        board: m5stack-atom
        framework:
          type: arduino
      

      Thanks

    • RE: M5Burner

      Hello @thaller

      it seems that UIFlow is not yet supported for Stamp C3U and therefore Stamp C3U is not yet listed in M5Burner. See here.

      DEVELOPMENT PLATFORM:
      Arduino, ESP32-IDF (UIFlow support coming soon)

      That said, there is a preview version of UIFlow which supports Stamp C3U. See this thread.

      Thanks

    • RE: M5stack Tough EXT dosen't seem to work...

      Hello @davmoz

      Re Modbus RTU: using Arduino code (not ESP-IDF) I can control an M5_ACSSR (relay) from an M5Tough just fine (using GPIO27 as RX and GPIO19 as TX). So I guess the GPIO assignment is correct, but I cannot tell whether your issue is with ESP-IDF or the SDM630, sorry.

      Re Tough Tools firmware ext I2C: The ATECC608B is a 'bad' example as it requires special timing to wake it up and as long as it sleeps it doesn't show up in an I2C scan. Can you try with another I2C slave? I had success with an M5Stack PbHub for instance.

      Thanks

    • RE: w5500 Lan v12 Base and SD Card

      Hello @basgoossen

      It is my understanding that multiple SPI slaves can be controlled by one SPI master as long as all code is running in a single task.

      That said, I think the issue is that two SPI masters are defined using the same GPIOs for SCK, MOSI and MISO. One SPI master is defined via M5Stack library (for TFT and SD card) and another is defined via spi_master (for LAN).

      Have you considered using an Arduino library for Ethernet as well, e.g. this one.

      I found an Arduino web server example which uses Ethernet and serves the index.htm file from the SD card. Please have a look here.

      Thanks
      Felix

    • RE: HSPI on M5Stack Tough

      Hello @hgi867

      you cannot use GPIO19 and GPIO27 - they are not connected directly to the RS485 port. See second schematic here.

      I had success using HSPI with the following GPIOs:
      SCK - GPIO33
      MISO - GPIO36
      MOSI - GPIO32
      CS - GPIO26

      Thanks

    • RE: M5Stack Core2 with M5Stack COMMU Module

      Hello @ratchapolp

      please see note here:

      Note:
      When using with the Core2, the base needs to be removed in order to burn the program properly.

      This has been discussed in this thread as well.

      Thanks

    • RE: ATOM-DTU-NB-IoT - modem does not respond anymore

      Hello @erazor

      ok, I see. Yes, I think getting in touch with M5Stack support is probably best.

      Thanks

    • RE: LAN W5500 socket listening does not work

      Hello @M5StickFreakler

      have you tried the example? It works for me.

      Note: the Init LAN block blocks until a client connects.

      Thanks

    • RE: ATOM-DTU-NB-IoT - modem does not respond anymore

      Hello @erazor

      I agree, I wouldn't expect 3.3 V peaks at the U1_RX side of the Q3. And yes, I guess the transistor could be broken, but it being broken in three devices - that is a bit hard to imagine.

      I never have used the TinyGsmAutoBaud code myself. I normally run all my modems with just 115200 and so far that worked just fine.

      Have you tried to measure what comes out of the modem, e.g. at transistor Q5? Maybe you can determine from that what baudrate the modem expects?

      Thanks
