  @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!

  @m5stack said in AXP192 coulomb counter issues: it seems like a bug. I will contact our engineer to solve this problem. Any progress?

  Hello @Dan95363 Have you had a look at the BM8563 datasheet? I don't think the BM8563 supports millis or nanos. I only see a register for seconds. Thanks Felix

  You can try this: https://www.google.com/amp/s/techtutorialsx.com/2017/10/02/esp32-micropython-creating-a-thread/amp/ But this may not work properly with all modules included in micropython firmware. You need also micropython version 1.14.

  @robalstona what do you mean by "check when the power button is pressed to power on device" ? I mean that this axp192 chip is always powered and waits for power button press to powering upthe esp32 chip and lcd with backligth. And check when this button is pressed for 6 seconds to shut down the power.

  I can confirm they are for M2 screws. E.g. for mounting a stick on the battery stick you'll need M2x10mm like shown here https://m5stack-store.myshopify.com/collections/m5-hat/products/m5stickc-18650 Turns the Stick into a nice handheld device for mounting a joystick, thermometer etc.

  @felmue I did not look at that. Will check it out. I played around with this for a while and made a number of modifications to the M5Stack C MPU6886 library to enable the FIFO and try to read from it based on the MPU6886 docs I found online. No luck, unfortunately. For now, though, I'm just going to stick with the standard method of reading the IMU. Burst reads on the FIFO are definitely something I'd like enable in the future, without it I'll drop data when I start doing real-time analytics. But for data capture over Wi-Fi that isn't an issue. I'm working on getting a nice tutorial together, here is my initial sketch https://github.com/sensiml/m5stickc_data_capture

  It seems the value is PWM duty cycle. So the volume increases in the 0-50% and then decreases in the 50-100%.

  For anyone else encountering Error 22 Battery Low, what worked for me is to SLOWLY charge the battery with an external 1S Li-Po charger using the Vbat pins. I'd say it's save to assume the battery went into deep sleep / protection mode. The way to 'wake up' a Li-Po cell is to slowly and carefully, under observation!, charge the cell. Since it's only a 80mAh battery i recommend to charge it at 5-10mAh. Once the cell is woken up, the external charger can be disconnected and the internal M5StickC circuitry charge it from then on. I hope that helps, this thread was in the top search results for me. (I also tried connecting a 300 Ohm resistor between 3.3V and Vbat, but that wasn't sufficient even though theoretically it should work)

  Hello @koichirose here is how I managed to get M5StickC Plus into deep sleep using MicroPython: p37 = machine.Pin(37, mode = machine.Pin.IN, pull = machine.Pin.PULL_UP) p37.irq(trigger = machine.Pin.WAKE_LOW, wake = machine.DEEPSLEEP) machine.deepsleep(20000) It wakes up from deep sleep either after 20 seconds or when button A is pressed. Thanks Felix

  @BricoMS Thank you for the answer. I thought, that the hardware/controller of M5Stick and M5Stack are the same and that MicroPhyton is just another way of displaying the blocks of UIflow. I do not understand why M5Stack made no "fair" advertisement/documentation. For me it would be "fair" if they would write "ESP32-based support BLE 4.2 and WiFi not compatible with UIFlow"" I think, for some (many ?) users the UIFlow possibility is an argument for M5Stack/Stick. regards K.D.

  @capatinshimapan When you switch on the StickC after burning the firmware you need to immediatly press the "A" button to access the setting menu. In the setting press button a to go into mode and be to move to usb mode and press a to select usb mode. Press the reset button and it should boot into usb mode.
