  @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.

  Hello @Shipbrook M5Unified uses Wire1 for internal I2C and Wire for external I2C. The example for SHT40 incorrectly uses Wire which causes issues as soon as other internal I2C communication is required, e.g. reading battery status. The quick way to fix this is replacing Wire with Wire1 in below line: //if(!sht4.begin(&Wire, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) if(!sht4.begin(&Wire1, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) The better way is to get the actual port used by M5Unified for internal I2C and the use that information: i2c_port_t PortIn = M5.In_I2C.getPort(); TwoWire * WireIn = (PortIn == 1) ? &Wire1 : &Wire; if(!sht4.begin(WireIn, SHT40_I2C_ADDR_44, SHT_SDA_PIN, SHT_SCL_PIN, 400000U)) Thanks Felix

  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.
