    @ไฟบใŒใ‚ฌใƒณใƒ€ใƒ ใ  said in LVGL performance problem: I applied LVGL on stickc-plus2๏ผŒwith TFT_eSPI's st7789v2 driver.But the refreshing rate is very low (while doing "load screen anim").I know stickc had good performance on drawing screen (by watching the video of M5stick T-Lite Thermal tutorial). And the LVGL also has a good performance through Dial-ESP32-S3 and Din-Meter demonstration video. So what is the reason of such low performance. Cound it be the TFT_eSPI library? Iโ€™ve seen similar issues on the StickC-Plus2. It could be due to TFT_eSPI settings, try increasing the SPI frequency or enabling DMA. Also, check your LVGL buffer config; full buffering helps with performance.

    Hello @Shipbrook M5Unified uses Wire1 for internal I2C and Wire for external I2C. The example for SHT40 incorrectly uses Wire which causes issues as soon as other internal I2C communication is required, e.g. reading battery status. The quick way to fix this is replacing Wire with Wire1 in below line: //if(!sht4.begin(&Wire, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) if(!sht4.begin(&Wire1, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) The better way is to get the actual port used by M5Unified for internal I2C and the use that information: i2c_port_t PortIn = M5.In_I2C.getPort(); TwoWire * WireIn = (PortIn == 1) ? &Wire1 : &Wire; if(!sht4.begin(WireIn, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) Thanks Felix

    Hello @daniyyel ah, ok. So the correct documentation is here. Have a look at the code examples in Quick Start Guide to see how the M5IOE1 needs to be programmed to turn on power etc. The function is called SIM7028_EN() and first turns on power then resets the modem. Thanks Felix

    I attempted to burn the firmware for each version of UIFlow 2.0 Stick Plus on my stickC Plus, but after each firmware was burned, the device failed to boot up and did not respond to any key press.

    @platycore I came here to find a solution myself, same error running on my Linux setup. After Googling it, all the responses where "pip uninstall -y enum34", but that was not the case. I found something interesting here: https://stackoverflow.com/questions/47878060/why-is-the-re-module-trying-to-import-enum-intflag I looked at the app location M5Burner_Linux/packages/tools/enum and that was it... the app has the wrong version of enum. Remove the one with the underscores: "_ init _.py" Copy the version of enum.py located in your /usr/lib/python3.8 path That worked for me.

    Hi Rob if you look into Power.cpp you'll see that the current already is set to about 400 mA: https://github.com/m5stack/M5Stack/blob/master/src/utility/Power.cpp void POWER::begin() { uint8_t data; //Initial I2C Wire.begin(21, 22); // 450ma setVinMaxCurrent(CURRENT_400MA); are you calling M5.Power.begin() in your setup code? Or maybe the current has been reduced due the the battery being close to full? Cheers Felix

    Thanks a lot, I was almost there! I tried the UIflow firmware. The configuration button gave me an error. The burn asked me to connect to wifi. I asumed that it was the wifi of the m5, but thought that it would not work because the core was without OS. After your suggestion I unboxed the Core again (it was ready to send it back ;-) And now up and running again. Many thx ;-) Hopefully after the update the env II sensor wil work now. Because there the troubles started. Out of the box it did not work. Now i will retry.

    @funkyfab said in USB driver for Raspberry Pi: I'll answer myself ;-) I copied the /lib/udev/rules.d/69-libmtp.rules to /etc/udev/rules.d, added the line ATTR{idVendor}=="0403", ATTR{idProduct}=="6001", GOTO="libmtp_rules_end" That prevents the M5 devices to be recognized as MTP devices. Then they're recognized as Serial ports, and Arduino IDE can access them. So we don't need the driver, just a change in udev configuration. Oh cool, thats for working out how to do this. I can continue my plans of adding an RPI to my project bench to programme the M5Stacks and Sticks. Thanks you.

    Problem has been solved The weak USB cable was to blame, after replacing the cable with the original Samsung, the problem did not return. Problem messages are: "BrownOut detector was triggered" and "The Guru Meditation" something like Blue screen of Death (BSOD)

    Resource manager won't load either BMP or JPG

    @devilstower said in Resource manager won't load either BMP or JPG: I've been trying over and over to load images to my M5StickC using the resource manager of UIFlow. I've reduced the size of the image I'm loading to just 2K. And I've tried saving it as 4-bit, 8-bit, 24-bit, and 32-bit. I've tried reducing .jpg quality to an abysmal 35%. I've pretty much toggled every possible setting for saving either BMP or JPG. But each time I try to load an image, the same thing happens. Resource manager displays the name of the image, a message appears that says "uploading" and then ... nothing. The message goes away, no error is every displayed, but the image doesn't appear in either resource manager or UIFlow. Images have to be very specific and the details can be found on page 35 of my WIP book found here - https://github.com/Ajb2k3/UIFlowHandbook/blob/master/quickblockref.pdf If you have followed the guide and still get issue then you may have discovered a new bug.
