For future viewers of this thread, the API key is the same as the MAC address. You can usually find this on your router config where it shows device info. The MAC is also shown in the serial output when you connect a burner device (or FTDI cable as mentioned above. My problem was the device was stuck and needed reflashing. Once I did that it worked perfectly using the 12-digit MAC as the API key. You may safely ignore the 8 digit "API Key" that is shown in M5burner or the command line, this was a red herring.

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

If the Atom is not connected to the host computer as it is when testing, you will need to add the WIFI AP and Password blocks to the start of the program.

@ajb2k3 Thanks for your support, we will share more interesting projects in the future.If you want a mechArm, please contact us!

@robjasey Cool, can't wait to see the finished project and please consider writing it up and posting to hackster.io which is where you can find a turntable project of mine.

Well, it's working. The path to my Windows profile has a space in it. I created a local account without a space, and my empty program compiled with no issues. Don't know if that's the reason. Very strange. Makes me want to reinstall Ubuntu, or something. Thanks for the replies, Terry.

@fbritop no as can’t get the m5specific libraries but the latest mainstream Micropython is available for the esp32 variants It takes a lot of searching and testing to find the correct compatible libraries

Ahh sorry, misread.

I don't think the PbHUB will work ... The PbHUB can only handle analog and digital signals (no clocks !). Reading values from the HX711 weight sensor needs a clock and a data line provided by the ESP32 GPIO Ports ... The UIFlow HX711 library only supports Port B. If you want to use several weight sensors on the M5Stack you will have to hook them up to different ports and do the programming either in Python or Arduino using the Expansion Port Module getting the additonal Ports C D and E. P.S: If you want to hook up multiple Weight Sensors to a M5Stack using port A you have to use HX711 devices which can be hooked up to the I2C bus. M5Stack has no such modules nor units, but you will find one made from DFRobot (https://wiki.dfrobot.com/HX711_Weight_Sensor_Kit_SKU_KIT0176). This sensor also has a grove I2C port and by modifying the I2C addresses you can hook up to 4 Weigh sensors to Port A. Using the PaHub I2C-extender you can even hook up 6 to 24 Weigh sensors ......

thank you for the reply ill try comenting that piece of code and see if it compile.

Hello @holofloh cool, glad it worked. Thanks Felix

I'm working on a book for the M5Stamp C3 using MP1.19.1 Going mainstream means a slimmer lighter faster MP but you loose access to the M5Stack specific libs and have to look for alternatives.

Using buttons and labels you can draw a screen table and use it as an on screen keyboard in order to enter the SSID and Password .. Pressing < > you scroll through the alphabet, with OK you confirm the letter... Much like setting and confirming your wifi credentials on an android TV When finished you connect to the Wi-Fi with the SSID and Password.

The python version of the c function looks like its probably not available: >>> dir(hardware.axp192.Axp192) ['__class__', '__init__', '__module__', '__name__', '__qualname__', '__bases__', '__dict__', 'deinit', 'setBusPowerMode', 'powerAll', 'setLCDBrightness', 'setPowerLED', 'setSpkEnable', 'powerOff', 'CURRENT_100MA', 'CURRENT_190MA', 'CURRENT_280MA', 'CURRENT_360MA', 'CURRENT_450MA', 'CURRENT_550MA', 'CURRENT_630MA', 'CURRENT_700MA', 'getTempInAXP192', 'getChargeState', 'getBatVoltage', 'getBatCurrent', 'getVinVoltage', 'getVinCurrent', 'getVBusVoltage', 'getVBusCurrent', 'setChargeState', 'setChargeCurrent', 'setLDOVoltage', 'setLDOEnable', 'setDCVoltage', 'disableAllIRQ', 'clearAllIRQ', 'enableBtnIRQ', 'setESPVoltage', 'setLCDBacklightVoltage', 'setLCDEnable', 'setLCDReset', 'setVibrationIntensity', 'setVibrationEnable', '_regChar', '_read8bit', '_read12Bit', '_read13Bit', '_read16Bit'] >>> However, I found two alternative ways to detect this, i2c being my favorite: https://imgur.com/a/nscmAHF

@teacdance 1-wire isn't supported in uiflow .. you will have to add an 1-wire to i2c converter: DS2482 -> https://community.m5stack.com/topic/1796/ui-flow-support-for-onewire-and-ds18x20/10 But you can use the MCP9600 with UIFlow (I2C-protocol).

@saitotetsuya said in ATOMS3 out of stock ?: https://twitter.com/M5Stack/status/1607967462393511942 Jimmy-san says it is in Mid-February. Thank you.

Look the information up on the M5Stack web page any search for it

@sleepyfatcat said in DigitalWrite: Hello, I am trying to use C to on the LED on my M5 stick c plus. I have initialise pin 10 as the output, and when I send digitalWrite(led_pin, 0), it ons the LED. My code causes the LED to on when 0 is sent, and off when 1 is sent. Any idea why it seemed like it is flipped? Thank you This apparently is normal behaviour for most ESP Cores from what I have found in data sheets and is very confusing.

You need to set up the WIFI functions to connect to a local network in program mode whereas, in test mode it uses the active default wifi setting the memory Is already using.
