    @俺がガンダムだ said in LVGL performance problem: I applied LVGL on stickc-plus2，with 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? I’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.

Diagnosis It is the driver for USB JTAG/serial debug unit (Interface 2) that causes issue. Reasons Using Zadig, found that the current driver is WINUSB (v10.0.26100.1150) The v10.0.x WinUSB driver is Microsoft's newer inbox driver that Windows sometimes auto-installs. It has been observed to be incompatible with OpenOCD's libusb on ESP32-S3 JTAG, causing exactly the LIBUSB_ERROR_NOT_FOUND error you saw. Visual Micro's own documentation explicitly warns about this: visualmicro Fix install Zadig replace/downgrade driver for USB JTAG/serial debug unit (Interface 2) to WinUSB (v6.1.7600.16385). NOTE: select "Install Driver" by clicking the dropbox on the button. The default option in the dropbox should be "Install WCID Driver" which will not help, it will still be the incompatible v10.0.x driver after Zadig installed the driver. Note on the USB JTAG/serial debug unit (Interface 0), the driver usbser (v10.0.26100.8328) is fine. There are Internet post that suggest replacing it with USB Serial (CDC). No need to make "Start Debugging" working. References IDE 2.3.0 debugging esp32s3 using built-in usb jtag Leveraging ESP32 Built-in JTAG for Advanced Debugging: A Step-by-Step Guide

    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

    How to debug Module LLM Kit when it silently dies?

    Ok, it worked finally. At least, I needed to use module_llm.melotts instead of module_llm.tts. The model specification in tts_config doesn't matter for my case. It picks melotts-en-default somehow automatically even though the default value is melotts_zh-cn. The module is very unstable when the controller is powered on. It requires several clicks of the reset button until it finally speaks. (The return value of melotts.inference is -97 when it's successful.)

    @simondid have you even tried to look it up yourself? Google's first hit is literally this thread from April, including a full ESPHome config. ESPHome also has a draft PR for including EPDiy as a generic display platform, and EPDiy itself has a PaperS3 pull request, which will allow the BMI270 component from the above thread to work (currently EPDiy tries to import some legacy code that breaks I2C, as patrick3399 used a custom fork of EPDiy that isn't exactly up to date).

    @Jomac said in Tab 5 screen flicker after firmware update: @sapphire said in Tab 5 screen flicker after firmware update: @Jomac If you watch the video, I have this little defect that doesn't happen often (a flashing). The link doesn't work for me Well I flashed the firmware several times and also flashed a couple of apps on M5Burner and nothing made any difference, everything just flickered so I switched off and left it for the night, next morning I was going to video the issue and when I switched on my Tab 5 again, the fault had cleared.

    Okay, posting to help others as I did find the solution to this. As the error message states, the binary has to be suid root. You can get it going by typing: sudo chmod 4755 bin/chrome-sandbox From wherever you installed M5Burner. This, and adding the current user to the dialout group, should really be part of the installation instructions. I can't see how anyone on Linux would avoid doing both of these steps. Now I if I can figure out why the Tab5 is bootlooping i'll be up and running...

    I'm curious—will the iOS version of EzData support the same modules and data types as the M5Stack Core devices? Also wondering if there's going to be integration with iCloud or local storage for exporting logs. I’ve been exploring some related iOS app development workflows, such as those outlined at Idea Maker, and wondering how closely EzData aligns with those practices. Looking forward to seeing how it develops.

    @Jomac said in Cardputer Driver Issues: @robski said in Cardputer Driver Issues: do you use m5burner? if so what com port it shows there when you connect cardputer? also what com port it is showing when cardputers on/off switch is in off and then you press and hold BOOT btn and then connect usb? It depends on how it feels, sometimes it will connect on Com 4 and other times on Com 9??? thing is that comport you see with just connecting cardputer to usb is one of two available second comport (needed for programming) is visible when on dead device you press and hold boot button G0 and then connect to usb

    For the M5Stack Core2, Grove Port A uses I2C on GPIO 21 (SDA) and GPIO 22 (SCL). However, when using a Pb.HUB, you're communicating with the hub over I2C, and each connected unit (like relays or RGB) is addressed virtually via the hub. Since openHASP doesn't natively support Pb.HUB devices, you can’t directly control GPIOs through it. Instead, you’d need custom firmware or integrate via ESPHome or Arduino to bridge Pb.HUB control with openHASP. TL;DR: GPIO 21/22 for I2C, but control of devices via Pb.HUB needs extra handling outside openHASP.

    @teastain Here the answer: M5.Lcd.print("Temp:"); M5.Lcd.print(t,0); M5.Lcd.print(char(247));M5.Lcd.println("C"); I guess you have found it meanwhile, but perhaps it is useful for others.

    Hey @roanevic, just jumping in here, I’ve tried that same setup recently. The example code Kuriko linked is a good starting point: https://github.com/m5stack/M5-RoverC/tree/master/examples/RoverC_JoyC_Remote It’s designed for StickC, StickC Plus, and the StickC Plus2, so it should work with your hardware. Just make sure you have all the necessary libraries installed (like M5StickCPlus2, RoverC, and JoyC) in the Arduino IDE. Let me know if you hit any snags setting it up.

    Hello @daniel-edge456 in UIFlow2 v2.2.6 using touch blocks for M5Paper and then look into the Python tab I get the following code to get touch coordinates: if (M5.Touch.getCount()) > 0: x = M5.Touch.getX() y = M5.Touch.getY() doing the same with power blocks I get: Power.deepSleep(1000, True) to put M5Paper into deep sleep. Thanks Felix
