  @jeffb no, no, no don't edit the files! There are 2 causes for the error that has plagued M5Stack since the beginning. 1st - driver issue. the driver is temperamental in osx and often does not work. 2nd and most important as its the biggest issue. The factory USB leads are often faulty and or just rubbish. Always use a high quality USB sync/data lead. something over the £10/$10 price range and never fold the lead, always roll it. I had this issue when I first started as I have only OSX. Also, when you install any new board or library in arduino, ALWAYS close arduino and restart it!

  @human101010 with the power on, click the power button and it will rest and start the sketch over. There is a more complicated procedure somewhere on the internet which I cannot find rn, on mobile! Did it ever connect? M5 did have supply different USB chips, you may need the CH340 patch.

  adding notes : the M5stickc plus uses an AXP192 for power management (including display), all the functions to initialise it are inside the M5StickCPlus but you can't call this library in same time as TFT_eSPI.h. you will have to copy AXP192.h & AXP192.cpp from the M5StickCPlus lib and put it in your project (change the names). If you have a M5 project loaded in your stick and then upload a sketch using TFT_eSPI, it will work the first time as the display is already power on from the previous m5 sketch but the display won't turn back on on the next restart unless you init the AXP192 like explained. hope it helps anyone!

  I ordered another C-Plus today and got the v1.1 revision as expected. There's a difference on the label - Sleep/Wake has been added next to the RTC box, see below. I would like to know what the relevance of this change is.

  Thanks! That workaround works. You only see the brief flash when applying power or when the IDE uploads the code and hard resets via RTS. If you do this: #include <M5StickCPlus.h> void setup() { M5.begin(); digitalWrite (M5_LED, HIGH); // turn off the LED pinMode(M5_LED, OUTPUT); digitalWrite (M5_LED, HIGH); // off } void loop() { delay(10); ESP.restart(); } the LED does not flash repeatedly.

  @m5stack connecting GND to G0 , when you upload program. I was getting the same error getting serial data from my M5StickC Plus. Doing this to update the firmware fixed my issue. Much thanks!

  I'm sure that the IMU is place so that Y points to the top of the StickC.

  @marciocobra Since no one has responded... to what does it not connect? Do you have the USB programmer, I presume? Does it not connect to Arduino IDE port? Or ESP_NOW, or WiFi or Internet!

  I was successful in recording something like a wave form with the following code: from machine import I2S, Pin import array mic = I2S(I2S.NUM0, ws=Pin(0), sdin=Pin(34), mode=I2S.MASTER_PDM, dataformat=I2S.B16, channelformat=I2S.ONLY_RIGHT, samplerate=16000, dmacount=16, dmalen=256) b2 = array.array("h", 4096 * [0]) mic.readinto(b2) However, there seems to be a systematic offset around ~+1000. Not sure what is going on here. Could it be related to PDM encoding and the I2S clock? Also, I experience values that are larger than the 12bit precision documented somewere def eval(): mic.readinto(b2) print(min(b2), max(b2), sum(b2)/len(b2)) for i in range(1000): eval() ... 48 1963 1017.062 811 1237 1027.727 927 1122 1021.952 849 1286 1023.281 763 1719 1029.73 102 1966 1015.185 -903 2878 1012.832 -788 2683 984.9133 -1524 2761 982.3828 -815 3075 986.0596 -864 3044 980.6567 -713 2904 993.0678 -669 2615 1014.595 -138 2182 1022.794 -73 1954 1018.482 ...

  I was in the same situation. I failed to update the board definitions that were already installed on Arduino IDE 1.8.19. Eventually, reinstalling the board definitions solved the problem. Specifically, I uninstalled the M5Stack board definitions on Arduino IDE 2.0, then added the URL for the board definitions, restarted the IDE, and then installed the M5Stack board definitions, which was successful.

  @fletli I have a video going up soon on how to get it to work in Micropython which turned out very easy in the end.
