    @ไฟบใŒใ‚ฌใƒณใƒ€ใƒ ใ  said in LVGL performance problem: I applied LVGL on stickc-plus2๏ผŒwith 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? Iโ€™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.

    @jukka-kahkonen To use the API key you need to install the UIFlow firmware using M5Burner. Once installed and the device connects to the wifi, the API key will be shown on the screen. The Puppy firmware was written in Arduino so does not have the api key. BTW the API keys are randomly generated with each new firmware install.

    Hello @oetzevandenbroek I think you are close. Try M5.Power.setExtPwr(false). Below is how it is defined: /// Set power supply to external ports. /// @param enable true=output / false=input /// @param port_mask for M5Station. ext_port (bitmask). void setExtPower(bool enable, ext_port_mask_t port_mask = (ext_port_mask_t)0xFF); In your case you want to set it as input to the M5Core2. Thanks Felix

    Getting closer... This is the string to change modes. Function switch Switch between different recognition functions by clicking the navigation bar of the function page or sending JSON commands through Serial Port communication. Note: Except at the end of the sent command string, no line breaks are allowed in other positions. { "function": "Camera Stream", "args": "" } BUT this is what I get in return {"error":"invalid json format."} {"error":"invalid json format."} {"error":"invalid json format."} {"error":"invalid json format."} {"error":"Command is not supported"} {"error":"invalid json format."} {"error":"invalid json format."} Anyone have any ideas? I'm sending the string through a serial termanal. CR,LF

    I am a little ashamed, it was not a driver problem. In M5burner I didn't give the information about the wifi which prevented me to burn my M5Stick. It's confusing, the error message is about a port problem. Thank you all for your answers

    try the following: set the stick to power OFF plug in USB (it will automatically power ON) look in M5Burner (or in your computers device manager) if the serial port appears. If not there is a driver issue on your computer or your USB cable might have broken wires (once happened to me) if the port appears burn the factory test or UiFlow I suppose there no need to put the stick in any special mode to burn the firmware. the internal USB chip will do that for you while the programm downloads. Once the UiFlow Firmware is running you have to set the mode for wifi or usb if not already done while burning firmware.
