Now I found working code for UIFlow 1.7.2, but this only supports PNGs:

from m5stack import * from m5stack_ui import * screen = M5Screen() screen.clean_screen() screen.set_screen_bg_color(0xFFFFFF) image0 = M5Img("/sd/images/sled150.png", x=0, y=0, parent=None)

Ok! So after connecting to the serial REPL on the Core2, it seems like the lvgl module is already setup on the UIFlow firmware, which is great.
I just wish that was made more apparent in the documentation somewhere.

@m5stack said in micropython flowlib missing sources:

@tialm we has plan to open source all Unit code. but maybe it need wait the UIFlow2.0 version finish

10 months later...

So has there been any updates on this? If i knew this would end up in proprietary BS again i would have bought something else. Wasn't the whole point about learning to program Microcontrollers to NOT be some random companies b*tch? The device is great. But like this its just a blockly-toy.

I'd be open to any other methods you have for wrapping text. Or even generic instructions for importing external micropython modules...

This works fine in my local python interpreter:

from textwrap import * joke = "This is a really long joke. This is a really long joke.This is a really long joke.This is a really long joke.This is a really long joke." wrapper = textwrap.TextWrapper(width=30) print(wrapper.fill(joke))

But when I try to run it on the m5stack device I get:

'module' object has no attribute 'TextWrapper'

Hmm, OK, get_wifi() works on 1.5.4, so maybe I just guessed wrong back then.

@sodoku I see! I'll try that code. Thank you!

Looks like rtc is included in one of the other files

from m5stack import * from m5ui import * from uiflow import * setScreenColor(0x111111) rtc.setTime(0, 0, 0, 0, 0, 0)

OK it works. So for future reference this is what I did:

Turn on the unit (mine is an M5StickC with UIFlow 1.6.6 firmware) press the M5 button quickly after that to enter setup mode (my screen shows <code>) side button to get the Setup menu M5 again to select it Switch Mode M5 again side button to select APP side button to select '..' at top M5 to go back to previous menu side button to select Reboot M5 to reboot

From now on whenever you turn it on the Stick will run boot.py and then main.py in the /flash directory.

If when it's so running you attach the device to a computer via the USB cable, you can interrupt whatever it is doing by starting Thonny and hitting ctrl-F2 (Stop/Restart Backend), which will bring up the MicroPython REPL prompt. Cool.

When devices start up, go to setting and set connection mode to USB. Default is set to Wifi/usb.

Hello @WonkoTheSane

Hmm, did you include the line from m5stack import *?

I have UIFlow 1.6.6 firmware installed on my M5StickC Plus and use Blockly's Set screen brightness block then switched to the Python tab.

Thanks

@mb You need to read a bit about py and c++ difference

Hello @toddkrein

you are correct, there is no RTC battery backup in M5Stack Fire.

Please note: In sleep modes time accuracy might be affected depending on the clock source used.

Please also refer to:

I'm trying to do this on the M5StickC and the "mkdir" command doesn't work. It just says "NameError: name 'mkdir' isn't defined"

Is there a different module on the M5StickC that holds these file system commands?
