  I am trying to use a M5stack 4-20ma module on i2c to a raspberry pi. I have got raspberry pi working with a env bme 280 module on i2c and successfully detected i2c address. Changing to the M5stack 4-20ma unit it won't recognise the module in i2cdetect. Any help or direction I need to take to get the M5stack 4-20ma and RPI working together on i2c.

  @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.

  I'm just transitioning to UiFlow after spending developing a lot of code with AnnexRDS, as UiFlow may suit my current project better. I have been able to load UiFlow into the Tough, which is usb-powered and recognised as ttyACM0.

  My first attempts at uploading a program into the Tough are met with "UiFlow wants to connect to a serial port" / "No compatible devices found".

  I'm confused as the burner can see it and has uploaded UiFlow V1.15.1 successfully, why cannot the IDE?

  I'm using Ubuntu and I know the Tough is seen by the OS.

  I imagine the problem is something really simple but I can't find any levels to pull that might help. I was hoping that UiFlow was a 'Just Works' kind of thing but so far I am stuck! Help please!

  Hi!

  I am having troubles downloading board management package from Arduino IDE latest version.
  Takes ages and ends to fail.

  I am also unable to download from Baidu, even with a translator I have tried everything.

  Is there any other mirror available for Arduino board management package?

  Any help appreciated!

  I've just finished work on a full feature micropythin driver for this Real Time Controller chip fitted to the Tab5 (and other M5 products etc.)

  https://codeberg.org/easytarget/rx8130ce-micropython

  As an example;

  # Create a I2C object # set sda/scl as needed, example below for esp32p4 from machine import I2C, Pin i2c = I2C(sda = Pin(31), scl = Pin(32)) # Create a clock object from rx8130ce import RX8130 clock = RX8130(i2c) print(clock.timestring()) # demo of timer from time import sleep # set a timer for 10s at 64Hz countdown clock.timer_enable(count = 640, tsel = 1) # wait for the timer while not clock.timer_interrupt(): sleep(0.1) print('.', end='') print('\nTimeout: ', clock.timestring()) # disable timer clock.timer_enable(0)

  This gives:

  MPY: soft reboot MicroPython v1.27.0 on 2025-12-09; Generic ESP32P4 module with WIFI module of external ESP32C6 with ESP32P4 Type "help()" for more information. >>> import test.py Fri, 30 Jan 46, 17:16:06 .................................................................................................... Timeout: Fri, 30 Jan 46, 17:16:16 >>>

  There is a lot more in the repo, including a demo of how to use the RTC to set the system clock at boot time.

  All the chip 'advanced' features can be accessed via the driver, but are of limited value on the Tab5 due to not having some pins connected, and the /IRQ pin being rendered almost useless by the power management mcu.

  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.
