  @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!

  I've just started out but it looks like the following shows the voltage and mine maxed out at 4.178V, this gradually decreases and I think below 3.6V isn't really usable. You can use this and some testing to determine the percentage of battery. #include "M5StickCPlus.h" TFT_eSprite Disbuff = TFT_eSprite(&M5.Lcd); void setup() { M5.begin(); M5.Axp.ScreenBreath(8); M5.Lcd.setRotation(1); Disbuff.createSprite(240, 135); Disbuff.setTextColor(TFT_WHITE); } void loop() { Disbuff.fillRect(0, 0, 240, 135, TFT_BLACK); Disbuff.setCursor(10, 10); Disbuff.printf("BAT_V: %.3fV",M5.Axp.GetBatVoltage()); Disbuff.pushSprite(0,0); } There are other options power functions that may help in this doc: AXP192 (Power management) Good luck.

  Finally got it working correctly. I had to use M5Burner to erase my M5StickC, and then set it all up again from scratch and reprogram it. At least I was able to get it to forget old wifi networks.

  Hello Jack you are welcome and thank you. You'll need to check the MPU6886 datasheet There is a sleep mode bit (Bit 6) in register 107 (power management 1). When I read that register I get 0x01 which seems to be the default. To put MPU6886 into sleep mode I'd write 0x41 into that register like that: import i2c_bus i2c0 = i2c_bus.easyI2C(i2c_bus.PORTA, 0x68, freq=400000) i2c0.write_u8(107, 0x41) Thanks Felix

  This is how I init my M5StickC in a full black screen way. M5.begin(0,1,1); M5.Axp.SetLDO2(false); M5.Axp.SetLDO3(false);

  It is for M5StickC Plus. M5StickC is nearly the same: https://docs.m5stack.com/assets/img/product_pics/core/minicore/m5stickc_plus/StickC_sch.webp

  @jhonnytank I apologize. I missed the fact that you were testing the hat. I only have the unit.

  Hi @AucT did you check out the M5StickC microphone sample? There is a GAIN_FACTOR which I would guess is probably what you're looking for. https://github.com/m5stack/M5StickC/blob/master/examples/Basics/Micophone/Micophone.ino Cheers Felix

  @felmue I wouldn’t assume a change in the sticker also represents a change in hardware. For example, I have the initial release of the M5StickC (no copper nuts, which are actually copper mounting screw holes), red 5V IN on the sticker, and no “RTC” label on the sticker. However, my device actually has a functional RTC inside. So adding the RTC label on the sticker doesn’t mean they revisioned the hardware and added the RTC. It was always there. I also cannot assume that the M5stack documentation is accurate 🤣. I think they make little revisions over time and don’t always communicate or document what was done.

  Thanks for posting that info, djhopkins2, it's hard to come across! I have found that this function keeps the board from shutting off after a few seconds, but I only started using an hour ago; I don't know if it has any adverse effects on the hardware yet: void disable_shutoff() { return M5.I2C.writeByte(0x75, 0x02, 0x00); } Also, here are the corrected voltage and current functions alluded to above; I don't think the voltage can go negative, but the current certainly does, and displays meaningless values without this correction: int16_t readBatV(uint8_t Reg) { uint8_t dataV[2] = {0, 0}; M5.I2C.readBytes(0x75, Reg, 2, dataV); if(dataV[1] & 0x20) dataV[1] |= 0xC0; // 14 bit 2's complement to 16 bit return (dataV[1]<<8) | dataV[0]; } int16_t readBatI(uint8_t Reg) { uint8_t dataI[2] = {0, 0}; M5.I2C.readBytes(0x75, Reg, 2, dataI); if(dataI[1] & 0x20) dataI[1] |= 0xC0; // 14 bit 2's complement to 16 bit return (dataI[1]<<8) | dataI[0]; }

  Hi guys Just a heads up on the new M5Core2 which has the IMU and mic on a micro board attached to the M5bus. As far as I can tell the interrupt pin of the MPU6886 doesn't seem to be connected to GPIO35 or any other pin on the M5bus which is a bit disappointing. Cheers Felix

  Hello @patf I just ran a test with an empty program (empty setup and loop functions) and yes, with that M5StickC can be turned off, but not turned on again via power button. Including M5StickC.h and instantiate M5.begin() fixes the power button and the device can be turned on again with a short press. Background info: M5.begin() calls M5.Apx.begin() which then properly sets up the PMU AXP192 chip in the M5StackC. Cheers Felix
