  The link to the PowerHub esphome code returns a 404. Is there another source for the code?

  @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.

  Just to share what I have done to get the debugging start working. Setup Windows 11 Adruino IDE Version 2.3.9 M5Stack StickS3 Symptom when clicking the Start Debugging button, encounter error messages as follows: Waiting for gdb server to start...[2026-06-07T13:03:42.505Z] SERVER CONSOLE DEBUG: onBackendConnect: gdb-server session connected. You can switch to "DEBUG CONSOLE" to see GDB interactions.

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

  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.
