  @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.

  @Handcannon UiFlow2 is not responding when I press "RUN" after upgrade to v2.3.6 hotfix2. Any idea why it happens? Thank you!

  I'm building a MicroPython app on the UIFlow 2.3.6 os for a CoreS3.
  The new m5ui LVGL widgets are wonderful, eg List, Dropdown, that are populated with touch buttons to make the selection. If there are more options than fit in the visible list a scroll bar appears and the list can be dragged. But this is made unusable by the scrolling speed .. I believe due to the animation speed.

  When I load 15 to 20 unattached strings (like with Blockly) the scroll speed is passable at first, but seems to get slower over time. The animation becomes painfully intrusive, until it is taking several seconds to ripple to a halt. I am deep copying the strings to the list, so there's no linkage or processing drag.

  Is there any way to change the animation speed, or turn it off? Or any other workaround suggestions?

  Thanks so much for any advice or suggestions.

  Hello @RubberDuck

  I can confirm the shark fin like signals on my M5CoreS3. I am no I2C expert, but I think they might be marginal and so maybe just barely working on one M5CoreS3 but not on the other when talking to AXP2101. Maybe a stronger pull-up resistor might help?

  BTW: I checked the I2C SCL line on an M5Core2 and it is much more rectangular, e.g. much more like I would expect it.

  Thanks
  Felix
