Alot of the core commands can be found by googling Micropython, Circuit python and Python.
The M5 Specific apis are proving more elusive and I'm doing my best to log them in my UIFLow book found in my github.

No pdf for S3, just C3

74HC4094D, IO extander, needs many pins

ESP32-D0WD => 48 pin (m5paper)
ESP32-C3-FH4 => 32 pin, with 4 Mo flash only
ESP32-WROVER => 38 pin (LilyGo), with 16 Mo Flash and 8 Mo SDRAM
ESP32-S2-FN4R2 => 56 pin, with 4 Mo flash and 2 Mo SDRAM integrated

SYL

No data for the S3 exist because it officially doesn't exist.
Some WIP samples are out in the wild but the information the testers have and IDF support is incomplete as the silicone can change.

You should be able to run up to 5 relay units connected to the i/ohub (pbhub).

@jimwsmith said in Separate firmware from M5burner:

@world101 It doesn't run on one of our students Windows 10 32bit machine

Does it generate an error message to say why it doesn't run?
There are many many reasons why it could fail.

@michaelxy the web version requires internet access as it programs "over the air."
The offline version is old and needs updating.
USB mode for the online version is experimental and depends on the status of the web browser.

@titimoby said in [M5Paper] UiFlow support:

As this is not my first M5 board, I think I was in App mode. But as the main source of errors is often between the chair and the keyboard, I'll focus my attention on this point 😉

I'm writing a book on the coreink and m5paper and spent a week trying to work it out!
now if i could only get the internal sht30 to work

OK, I got it.
To use Thonny or other micropython IDE's with the M5Paper, you need to put the paper into "App Mode" in the menu as UIFlow and USB mode do not allow access to REPL.

temperature, humidity = sht30_sensor.measure()

I can't get this to work

  File "<stdin>", line 1, in <module>
  File "sht30.py", line 40, in __init__
NameError: name 'I2C' isn't defined

I honestly don't understand M5Stack's way of working. There is this ENV2 with python support: https://docs.m5stack.com/#/en/unit/envII it has a SHT30, but then you spend $80 on a M5Paper and you don't get python support for the SHT30. How hard is it to put in the the right lib.

I know I can do it myself, but M5stack should have done this already :-/

Micropython on the M5Paper is in early alpha because we pushed M5Stack to get it out before the holiday. I spent yesterday doing some testing and I cannot get any SHT30 devices to work no matter if its the internal SHT30 on the paper or the env2 unit.
What lib are you using as I cant even get raw reg read and writes to work.

@a1exandr you found Kapton tape on the sensor?
You need to message M5Stack about that as it should have been removed during assembly.
