  Hello. I’m trying to read data via usb_uart on an M5Stack CoreS3 from a CDC-ACM device, without success.
  Here some config entries.
  I moved the logger to a different interface. I have no idea whether this is necessary, but this way it definitely doesn’t occupy the USB interface.

  logger: baud_rate: 0 hardware_uart: UART0 level: VERBOSE initial_level: DEBUG logs: usb_uart: VERBOSE usb_host: VERBOSE uart_debug: VERBOSE

  Outputs

  output: - platform: axp2101 type: range channel: DLDO1 id: lcd_backlight_output min_voltage: 2600 max_voltage: 3300 - platform: axp2101 channel: ALDO1 voltage: 1800 - platform: axp2101 channel: ALDO2 voltage: 3300 - platform: axp2101 channel: BLDO1 voltage: 2800 - platform: axp2101 channel: BLDO2 voltage: 1500

  Then I set these switches:

  switch: - platform: gpio name: "bus_out_en_sw" internal: true pin: aw9523b: aw9523b_hub number: 1 restore_mode: ALWAYS_ON - platform: gpio name: "usb_otg_en_sw" internal: true pin: aw9523b: aw9523b_hub number: 5 restore_mode: ALWAYS_ON - platform: gpio name: "boost_en_sw" internal: true pin: aw9523b: aw9523b_hub number: 15 restore_mode: ALWAYS_ON - platform: gpio name: "AW RST P0_2" internal: true pin: aw9523b: aw9523b_hub number: 2 restore_mode: ALWAYS_ON

  And configure the usb_uart

  usb_uart: - type: cdc_acm id: scanner_bus vid: 0x152A pid: 0x880F channels: - id: uch_1 debug: true

  The device is a barcode scanner Digitus DA-8002
  DC 3.3 - 5V, 120 mA, idle 1uA
  The scanner is set as "USB serial interface output".
  Adapter USB-C to USB-A Greencell 2.4A 480 Mbps
  Power supply CoreS3: Yingjiao YS35V-1203000, 12V, 3A, 36W
  Baudrate scanner: 9600
  The scanner is powered. When I plug it in, it beeps, and it also beeps when I scan.
  It has a USB-A interface, and I’m using a USB-C to USB-A OTG adapter.
  The scanner works without any problem with this exact adapter on a Windows PC and on an Android smartphone.
  This is the log when I plug in the scanner.

  As it looks, the transfer is submitted with usb_host_transfer_submit. There are absolutely no error messages and everything looks correct. The callback is just never called—no matter what, how much, or how fast I scan.

  What did I forget? Is this even possible at all?

  @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.

  You are right. I now use pin 33. All sensors keep updating.
  Now i have to built a relay cirquit for our 230volt net.

  Thanks!

  Update on this one:
  Changing to other pins for external I2C makes it work for both Arduino and PlatformIO.
  So with arduino you can lay external I2C over the internal I2C, but in PlatformIO that does not work. Anybody an idea why not?

  Hi! Thanks to both of you for your answers.

  I managed to get it working by using a different approach-via Wi-Fi. However, I’m still curious: why couldn't I connect via UART?

  I suspect it might be related to the camera's firmware. It seems like the Unit CamS3 5MP Wi-Fi doesn't have default firmware to stream JPEG over UART. Is that correct? I’d love to understand why it works over Wi-Fi but fails over UART. I either managed to connect with camera (pin 17 and 18) but couldn't get any data back.
  Any insights would be greatly appreciated!

  Hello!

  I am new to the community here and have been finally been playing around with my m5stack core2 with rust.

  My project consists in a simple voice recorder which does the following:

  After pressing a button, start recording from the microphone to the SD card Show a timer of the elapsed time Once the user presses the stop button, stop the recording Then upload the recording to a server

  I got every bit working independently but the problem is getting them to coexist.

  The reason I am posting here now is that I am completely unable to figure out how to get the display to work (e.g. update the elapsed timer and/or react to user button presses) while also having an active microphone recorder which writes a wav file directly to the SD card.

  I found quite a bit of conversations about it being a limitation of how the lines are shared between the display and the sd card. Some even suggested the existence of some workaround to get them to work but I couldn't get any to work with rust/esp-idf.

  Has anyone here managed to get this to work? I would be pretty surprised if 2 such core features (the screen and the SD card) were really not possible to coexist, as that would destroy almost all my project ideas for the m5stack.

  I would like to build a line follow robot and read the analog values of three sensors. How can I connect three Unit Reflective IR via Unit PaHUB V2 to my AtomS3 Lite? It seems in the UIFlow2 GUI I can only add a single Unit Reflective IR. And it needs some custom pin input?
