The only information I found is the post from https://namakeguma.com/?p=93 Which indicates some inconsistent behaviour across devices, but that setShowLock(True) as expected batches the led update until the next show() (or setShowLock(False); show() ) call. (thanks Google translate!) Official documentation or source code instead of random japanese online blog posts would be welcome.

Bad, works when plugged to computer but DOESN'T WORK when standalone :(

Hello NYCMS, WOuld you mind pointing me the tutorial or similar you used to get your VSCode and Arduino CLI toolchain working? Thanks.

That’s coming but there are differences in the various versions and so collect them is a challange. The UIFlow2 version with the drivers

the GP is not required, only numbers are required.

@gavin67890 said in Where is the API ?: Hi @cognitive5525, Were you thinking more like a M5Stack reference rather than how-do document? I would love that. Maybe like this https://docs.m5stack.com/en/uiflow/hardwares/microphone with further breakdown of each function with syntax and parameters in MicroPython code. Yes a reference as you'll find for the stock Micropython. Tutorials or Howtos are also find but usually only in the very beginning. Have you tried using Visual Studio Code to program devices directly? I might try Thonny because I need something that works across macOS, RPi and Linux. VS Code was ideal, and I have been using it, but I couldn't "add device" when I tried on macOS today. I tried it once or twice with VS some time ago, but I couldn't get the plugin work well. It was difficult to establish a stable connection to the devices. I had to tweak Thonny though: https://community.m5stack.com/topic/5268/micropython-for-atom-s3-lite/4

Hello @AdamMillionP having two devices using the same IP address is never a good thing in any network. The other thing which needs to be different between clients is the MQTT client id as it is used by the Mosquitto broker to distinguish between clients. Thanks Felix

Hello @ttmetro the DIN BASE contains a DC/DC converter. See schematic here. Thanks Felix

Micropython/UIFlow library's slow Modbus access may be due to inefficient code implementation or hardware limitations. Check for optimizations, reduce unnecessary delays, and ensure proper configuration. Additionally, consider hardware capabilities for better performance.

inter-erasure? I don't know what autocorrect did to my comment, sorry! The S3 does NOT work like previous generation devices and you have to put it into "Boot Loader" mode by holding in a button before a serial connection can be open to use the REPL terminal.

@tazfranck You can find a generic esp32 D0WDQ6 version on the Micropython web site.

@ajb2k3 any update on the tutorial? Would be greatly appreciated for all newbies :)

Hello@margel The description in m5-docs is done with setTextColor. https://github.com/m5stack/m5-docs/blob/master/docs/en/api/lcd.md setTextColor( color, backgroundcolor )

Rather, I chose to switch to polling, which worked much better, so it seems.

Way hay I got it. in micropython you use i2c.writeto_mem(0x45, 0x00, b'\x01') to set the mode and then i2c.writeto_mem(0x45, 0x10, b'\x01') i2c.writeto_mem(0x45, 0x10, b'\x00') to turn each pin off and on it digital mode. And I can conform that the EXT I/O 2 and the ExtI/O stamp are the same units!

@teastain I have had a few issues with the SHT30 sensor. For a start, Hardware I2C is broken in micropython but SoftI2C works fine. On a core2 I had to use the PaHub to get the SHT30 to read. I have solved my initial problem in that it was the conversion formula I had wrong.
