  This is a template for connecting Unit MiniScale to ESPHome. You can use it as a basis to create external components that connect to other M5Stack Units.

  @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.

  More information

  If I use M5Unified.h and then a begin of M5.begin(), the data is all zeros. If I take out the begin, then the data is correct. There must be something in the M5Unified that is restarting the Wire or taking over the I2C bus.

  How can I correct this. It is a show stopper. If I can find a solution, then I will have to discard the M5Stack basic and go to a regular ESP32.

  @Paulskpt

  Thanks for that.

  Do you know where to find the papers3 micropython documentation ? I prefer to write directly in micropython (vs uiflow), as I have already an application I would like to port to the papers3.

  Thanks

  Problem already fixed with only two lines of code:

  esp_sleep_enable_timer_wakeup(50000); // 50ms esp_deep_sleep_start();

  A very short deep sleep will power off the GT911 chip and power it on again, so that fixes the problem.
  Thanks to the chatbot!

  Got the Tab5 last week and been doing different Uiflow2.0 sensors and Lights etc. Just playing with it.
  Problem is that all of the Programs with just sensors and no buttons work great. Can reset back to menu and load from device. Anything with buttons locks up the Tab5 after loaded and configured from M5Burner after download. Core2 and Core3 all run find with the updated firmware. Any ideas???
