      Hi @infinitool , So when you unplug/plug the device in, the serial port doesn't even show up? If the port does not show up on your computer, then there are other issues. You can see these instructions or the link to Espressif's documentation for identifying the port for each OS: https://edukit.workshop.aws/en/blinky-hello-world/device-provisioning.html#identifying-the-serial-port-on-host-machine You can use PlatformIO. As a matter of fact, the Getting Started guide explicitly uses PlatformIO: https://edukit.workshop.aws/en/getting-started.html.

      Hi guys UIFlow 1.7.1.1 for M5Core2 is out and it seems to fix at least the no power issue on port A. @m5stack : is there anything else that has been fixed on 1.7.1.1? Just curious. Thanks. Happy Stacking! Felix

      Hello everyone, I just wanted to chime in and mention that with UIFlow firmware 1.7.1.1 that I also do not have the RGB leds showing up as hardware options in block view in the UIFlow IDE. I do not have the "Set bus power mode" as an available block. I CAN however call rgb.setColorAll() and other rgb functions from the python code and get the correct output from the LED strips on the Core2 M5go Bottom2 hardware. So I am not sure what that means as far as where the bug is. Thank you!

      @world101 Thanks for your reply. For the project I have in mind, I just only need beeps, but if I'm going to hack around, I'll try to attach a speaker since it would allow me to do many other things. For programming I'd go with Arduino.

      I

      Since UIFlow display nothing on the screen, I tried the test with the ILI9341 library for MicroPython I found. https://github.com/tuupola/micropython-ili934x/blob/master/ili934x.py I copied the above library to Core2 and ran the following code from the serial console. import ili934x from machine import Pin, SPI spi = SPI(miso=Pin(38), mosi=Pin(23, Pin.OUT), sck=Pin(18, Pin.OUT)) display = ili934x.ILI9341(spi, cs=Pin(5), dc=Pin(15), rst=Pin(4)) display.fill(ili934x.color565(0xff, 0x11, 0x22)) display.pixel(120, 160, 0) display.print('1234567890 ABCDEFGHIJKLMNOPQRSTUVWXYZ') : : : display.print('1234567890 ABCDEFGHIJKLMNOPQRSTUVWXYZ') As a result, the characters are displayed as shown in the image below. I'm not sure what this means, but can it help analyze the problem?

      Well as long as it comes ... ideally 2021 ... im cool ... was just afraid there would be no support at all ... since I dont plan on learning C or using arduino ide .... Hopefully this is just the start of bigger screens.... I would love to have a bigger m5 lcd version as well

      @powersoft Found the solution. After setting into the preference the right url and loading the m5stack I was able to choose the M5Paper. Examples are running now👍

      Hello @veryalien starting with bus power mode 1 (aka using external 5 volts) is important if one wants to use modules like the Ethernet Module which can power everything from a single power supply (and w/o the need for USB). If the setup block sets bus power mode to 0, the system would shut itself off in that scenario, before the user code can set it back to 1. To be honest, I don't know what the best approach for UIFlow should be to make it simple and powerful enough for different scenarios. BTW: one of the reasons I personally do not use UIFlow - too many areas which I cannot control. Thanks Felix

      Hello @hseidel re-reading FAQ Q36 I think the compatibility is about GPIO compatibility (electrically) and not about pin length. BTW: I double checked the length of various modules I have (Battery, Proto, M5GO, M5GO2) and afaikt they all have the same length of pins. Some of them have been bought before M5Core2 came out. Maybe they all have the longer pins already and I do not have modules with shorter pins? Anyways, I do not have a connectivity issue when stacking any of them to my M5Core2, but yes, the connection feels a little weak sometimes. Thanks Felix

      @mati I bought 5 16gb cards, tested them yesterday, they work fine. But, I have 32gb that work in all my pc's and my phone but don't work in my m5paper. I did have to use as CS of 4 in the SD.begin() call, this is not documented in the SD_Test example.

      Bit confused as to why the 'Data' is ignored in GET. Switched to POST but data is still not delivered. I will continue to test and se if I can isolate issue.

      Hello @shay sorry, my bad. I incorrectly assumed you'd be using an M5GO2 bottom with your M5Core2 which exposes ports B and C. You are correct, the only port directly available on M5Core2 is port A, which by default is used for I2C and not serial. So yes, I guess the easiest for you is to get an M5GO2 bottom. Thanks Felix

      U

      I think it's faster to just replace the mbus connector to a fullsize one if there is a smd version. Especially since aliexpress declined my dispute, not turning on seems to be not broken enough.
