    • RE: UiFlow 2.0 Alpha verison discuss(how-to, bug, feature request or sometings)

      @erich

      Here's the FCC submission for M5StickC Plus 2 include internal and external photos:

      https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=6654502

      Apparent differences to M5StickC Plus 1.1:

      • AXP192 is removed as it is end-of-line
      • Magnet is now one small disc instead of two small bars
      • battery lead is socketed
      • now one board instead of two
      • IC is ESP32-PICO-V3-02 instead of ESP32-PICO-D4 (now doesn't support external PSRAM, not relevant though). PICO-V3 has extra pin 20 for internal use.
      • 200mAh battery instead of 120mAh
      • Not clear where the buzzer is or whether there is no buzzer - not on the inside back as per M5 Stick C Plus.
      • The rear sticker shows a few differences in internal GPIO pin allocations.

      The twitter post @gavin67890 linked to says its been delayed due to some further changes though.

    • Use of the M5 Stack logo in projects

      Are we permitted to use the M5 Stack logo in our projects? I mean specifically as a label on the outside of the product like I have done for Blue Robotics in the hackaday project linked below and in the photo attached. The logos showcase the technologies used in the product.

      I am using not one, not two but three M5 Stick C Plus cores in this project! I want everyone to know that it's powered by M5.

    • M5 Stick C Plus: Sat Nav & Telemetry Console for Scuba Divers

      Please check out and follow my new project on hackaday. It uses not 1, not 2 but 3 x M5 Stick C Plus cores!

      Thank you so much!

    • RE: M5 Stick C Plus 5V HAT output

      Thanks @teastain. Is there an API to tell what the 5V In voltage is from the HAT? I use the USB voltage to work out if the power has been cut so that I can automatically shutdown the device instead of using battery power. I wonder if this can also be done through the HAT power in...

    • RE: M5 Stick C Plus 5V HAT output

      I've given up on this, now powering it direct from USB instead of HAT.

    • RE: Factory Test and Microphone example not compiling M5 Stick C Plus (latest version)

      @bazman Fix is to delete the line! Both the microphone example and the factory test project then work.

    • M5 Stick C Manual found - where is English Version?

      This is in Chinese for M5 Stick C. Does anyone have a URL or the PDF for the english version of this document and for the M5 Stick C Plus English manual equivalent?

    • What is spec of M5 Stick C-Plus IR Transmitter?

      I want to build a receiver of Infra-Red to detect transmission of IR from M5 Stick.

      What is the transmitter diode used in the unit? I need to know the frequency response and the infra-red band that is transmitted.

      The best info would be the actual manufacturer and part number in the M5 stick.

      Thanks!

    • M5 Stick C Plus 5V HAT output

      The M5StickC-Plus is being powered through USB.

      The grove port is in use, connected to a temp/humidity sensor (Adafruit AHT20) and magnetometer/accelerometer sensor (Adafruit LSW303AGR).

      I am connecting an RS485 board (using a MAX485 IC) to the HAT pins, but the 5V output is only at 1V.

      Any ideas? Does the 5V output have to be enabled in code?

    • RE: M5StickC-Plus changes in version 1.1

      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. 0_1676992885844_M5Stick-Cplus diffs.jpg

    • M5StickC-Plus changes in version 1.1

      (I originally posted in General forum but had little response, here is probably more appropriate)

      There was an update in December 2021 to M5StickC-Plus that is reported on the C-Plus docs page as:

      "Added hibernation and wake-up functions, and changed version to v1.1"
      from: https://docs.m5stack.com/en/core/m5stickc_plus

      I have the original M5StickC-Plus. Are the changes to v1.1 related to new hardware, new firmware or new libraries? Can these new functions be used with the original M5StickC-Plus through an update? Can you link to the documentation for the changes too?

      Thanks

      Mark

    • M5StickC Plus - detect power button momentary press?

      I can't find a way to detect a momentary press of the power button on the M5StickCPlus, only button A and button B detection is described. Is there any way to do this in C++?
