    • RE: GROVE I2C 5V or 3.3V?

      The conclusion is that the 5V Vcc cannot connect to 3.3V device.

    • RE: Suggestions for future releases.

      The Grove's Vcc would be nice to be 3.3V as the ESP32 is powered by 3.3V. Also, the Grove socket/connector is too tight, so much so, Grove male connector will break the edge.

    • RE: cp210x.ko driver - invalid module format

      I gave it a go using all esp-idf components and a program without M5Stack. I then hit the command, "make flash monitor". The result is as what you said. Awesome!

      I would like use your source to get the TFT LCD screen to work first. Do you have any advise for me that I should aware, avoid, etc, please?

      Thank you

    • RE: cp210x.ko driver - invalid module format

      Did you refer to the driver or the M5Stack-idf? All my esp-idf drivers and examples as well as the Webradio Bluetooth Speaker work without any issues. Can you be more specific, please?

      Has anyone encounter similar problem in Ubuntu?

    • Failed to compile Linux_2.6.x_VCP_Driver_Source in Ubuntu

      I read the description of the environment it was modified CP210x driver for the 2.6.38 kernel (Ubuntu 11.04).However, I am now running Ubuntu 16.04, 4.13.0-35-generic.
      See the error messages below. Is this driver still needed to program/use M5Stack. If yes, has anyone succeeded compiling it?

    • M5Stack and esp-idf

      Hi there,
      I haven't seen much information on M5Stack using esp-idf FreeRTOS. Hence, I would like to know if anyone out there using M5Stack with esp-idf which is FreeRTOS. What about those drivers, such as TFT-LCD, MPU9520, GSM, etc, are they available in esp-idf?
