UiFlow 2.0 discuss(how-to, bug, feature request or sometings)

hardware: core 2 for aws
Firmware: UIFlow 2.0.0 Alpha-28

When I choose run once my .py file in APP.LIST(or APP.RUN). It always said some modules not define.
Choose Run always would work though.

I think is some problems about import module
because I tried "M5.Widgets.fillScreen(0x222222)" instead " Widgets.fillScreen(0x222222)", and it works.

My imports have two of these:
import M5
from M5 import *

@sgu I too have been worried about this, as I jumped in feet-first to m5stack and figured the lastest and greatest devices would also have the best support. Its silly that something as trivial as displaying the current battery level requires code execution blocks. I had to order an older device just so I can test out some of the modules and sensor units I purchased. Think I'm just gonna give up on UIFLow and invest my time in Arduino IDE.

@j_doe I need help with this one. Cannot get any UART program to work on CoreS3 with UIFlow2. I am using CoreS3 as a co-processor to a Raspberry Pi using serial coms but my initial unit testing is being done on a Windows PC working with Putty. Here is the program:

What I want is an equivalent program to this which uses an original Core computer. It is based on UIFlow 1 (V12.1.9)

I am using the latest firmware & on-line UIFlow IDEs (Alpha-28)

On the Core program I had to decode before I could access text from the UART - might need a similar solution for UIFlow2?
On the UIFlow1 program I accessed the Core UART using pins TX:1 & RX:3. I am guessing that the equivalent pins for CoreS3 are TX:43 & RX:44?

What is the status of adding features to UIFlow2? I recently bought the core, core2, and core3, as well as the M5Paper. I am having a blast with blockly for the core, but most of the blockly code is missing in UIFlow2. For example, getting the current battery status is missing. There isn't an option for power in hardware, like there is in UIFlow. I also would like to request you do not change the GPIO again. For me half of the draw to the M5stack devices is that the modules and sensors work out of the box. Having modules that no longer work with the core3 due to a different GPIO pinout sucks. Keep up the good work and please take these as suggestions and not complaints. I love your product, I just want more software support in the form of UIFlow2. Thanks!

Is something wrong with UIFlow2 website right now? I cannot get my CoreS3 or my Atom S3 to utilize any of my sensors. Theyr'e all saying "Unit not defined" in the console as soon as I add any of them to a project.

[jazztunes]

@jdbaluch I had the same problem with uiFlow2 + AtomS3. Check the code window and see if any imports are missing, particularly the unit import. Should be something like:

import os, sys, io
import M5
from M5 import *
from hardware import *
from unit import *

On mine, the unit import was missing. I tried

• Switch to various different units
• Fresh the website completely (F5, clear cookies, close tabs etc.).
• Re-flash the unit with m5burner

Somewhere in there, the unit import line decided to show up and then everything started working. ¯\(ツ)/¯

6 Months later. Just flashed the Core S3 with the newest UiFlow 2.0 Alpha and still the modules are not integrated!
Do you really want to sell the Core S3 ? without complete software support, the use cases for the Core S3 is very, very limited.

[codeblue]

is the UIFlow2.0 desktop edition available now?

[li0than]

wlan config misses reading of essid. Could you add this?

Also would be very cool to have a way, where Block editor keeps working when only minor changes were made to the code.
(when adjusting one variable cuz its not yet available, it would be awesome, if I could still keep using the block editor)

[felmue]

Hello @li0than

you could use the Execute mpy code block for stuff that is not (yet) available.

Thanks

@iamliubo , When using a m5 dial it would be really nice to center text in a label in an easy fashion.

I am building a distributed smart control system for my sail boat using 6 m5Dials one in each cabin. They show all important boat data such as depth and wind speed and heading from an MQTT server running on a raspberry pi the also show alerts and allow control of local lighting.

I am having a lot of problems with UI Flow 2.

All I have working so far is lighting with dimming using the dial and night lighting (RED lights) working.

I need to get RFID working to login crew/family members so the m5Dials alerts them to their watches - I get an error when I put in any RFID blocks except "RFI init built in" I have an "if" in my main loop that calls a function if a new card or RFID phone is detected the function currently only reads the card ID converts it to a string and shows it on a label

My other problem is connecting into the MTTQ server this currently always hangs the device and I need to power cycle it to get any responses

I have MQTT code working on my m5 coreInk in uiFlow 1 which I am using for remote anchor control

I have plans to open source the project and I think it will be very useful for other sailers

I also want to do some YouTube system build videos but they will only currently show it not working!

I think I am expecting too much from alpha software.

Any suggestions or advice are welcome.

Hello,

I've installed UiIflow via m5 burner and after that my card computer don't starting at all, only red light on esp32. And I can't install any other soft

[ajb2k3]

Uiflow is not for the S3 generation of which the card computer is based on, you need UIFLOW2 (please read the information printed in M5Burner first)

UIFLow2 does work on the Card computer but the current version is only for the StampS3, the card computer isn't yet configured.

re:MQTT for me so far only mqtt config as "execute code" is working while using Uiflow2 - built in mqtt blocks didn't work - im connecting to HiveMQTT btw,

re:rfid when I had test M5Dial project installed then i could detect/read any of my rfid tokens but when I've tried to use built in blocks for rfid in Uiflow2 had no success really - I need to try harder

Hello @m5stack

UIFlow2.0.1 - M5 Cardputer : when I add Init keyboard and When keyboard was pressed blocks I get the following Python code:

def kb_pressed_event(kb):
  global kb
  pass

def setup():
  global kb
  kb.set_callback(kb_pressed_event)

  M5.begin()
  kb = MatrixKeyboard()

Unfortunately kb.set_callback(kb_pressed_event) is placed before kb = MatrixKeyboard(). E.g. before kb is defined. Resulting in AttributeError: NoneType object has not attribute set_callback.

Also in the callback function global kb is added which results in the following SyntaxError: identifier redefined as global.

BTW: running code:

def kb_pressed_event(kb):
  pass

def setup():
  global kb
  M5.begin()
  kb = MatrixKeyboard()
  kb.set_callback(kb_pressed_event)

Please fix.

Thanks
Felix

[felmue]

Hello @m5stack

thank you for fixing the first part.

However the second part is still wrong. Below code created by the When keyboard was pressed block:

def kb_pressed_event(kb):
  global kb
  pass

still returns a SyntaxError: identifier redefined as global.

Please fix this too.

Thanks
Felix

It seems like I can't download my programs anymore, neither in Wifi nor with the USB-C cable. I have a M5Stack Core2. This is what i get both ways :

Hi All.

New here and quite confused. Got the stickCplus2. Love the device, but writing/blocking some code is a pain in the a.. atm.

Can't seem to recreate the experiment in the docs (https://docs.m5stack.com/en/quick_start/m5stickc_plus2/uiflow); turning on (one of) the LED(s)? In the docs it's blocked with the PIN blocks. Why are those not in the 'built-in hardware' section? The LED's are built-in, right? But also the exact same compilation as in the example does not turn on a LED when run.

Then in the built-in section you can choose RGB, which definetely is not built-in?

Some schematic overview of what button/led is which in the code language would be nice. (Just a picture of the device having the code-name next to where it would be placed in the device. Understand what I'm trying to say?

Is UIflow1 still more stable? Must say, UI2 looks very good. But that's about it for now it seems.

Sorry for such a long comment already. Got a lot more questions, but I will come back with those later. Still a noob in the esp32 anyway, so I'll keep trying to find out stuff by myself as well.

Cheers!
