  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?

  UiFlow V1.14.1 does not show Display (Module) under the list of modules when Core2 is selected as a device. It does show Display as a module when Core or Fire is selected. Based on the documentation Core2 should be supported.

  With the UIFlow 1.x Micropython firmware it was possible to work with multiple screens using the M5Screen class.

  How can this be done with the UIFlow 2.x firmware? I see there is a Display class in the M5 module and some functions which look interesting:

  Displays() addDisplay() getDisplay() getDisplayIndex() getDisplayCount() setPrimaryDisplay()

  I couldn't find the documentation for these functions. Are there any docs explaining how to use them or some example code?

  Any idea? Is it possible to use it with http get or MQTT commands?
  Any pointers?
  Thanks

  Hi, I am using a CoreS3 with UIFlow2. It appears to me that the local time function is bugged with its calculation of weekday and yearday.

  Below is what stated in the UIFlow2 programming guide about the function.

  Below is my code UIFlow2, just to display UTC time and local time of several different timezones.

  Below is the output on my CoreS3 screen.

  It appears that UTC function displays both weekday and yearday correctly. With Jan 25th being a Saturday, it shows 5 (Saturday) and 25 for weekday and yearday respectively, as what can be expected according to the programming guide.

  But local time function appears to be bugged:

  For GMT0, the date is also Jan 25th (Saturday), but it displays 6 (Sunday) and 24 for weekday and yearday respectively.

  For GMT-12, the date is Jan 26th (Sunday), but it displays 0 (Monday) and 25 for weekday and yearday respectively.

  Is it indeed a bug, or do I just misunderstand the local time function?
