Hello, could you add more RTC blocks to Uiflow2? Like the ones in Uiflow1? I'm a beginner and I wanted to make a simple clock app for the cardputer but for now seems impossible for me without learning to code. Also it would be nice to have all the apps I built in the App.list section of Uiflow2 on my cardputer. Thanks!

I'm using UIFlow2 on Microsoft Edge and when I try to create a variable with the name of an object that already exists, I get the conflict information and even if I correct it, when I exit the variable creation window, UIFlow2 crashes and I have to reload the page to continue.

missing magnetometer scratch code for atom s3r , please add

[kuriko]

@riztronic
did you mean a built-in magnetometer?

[teastain]

@riztronic The device includes a 5V to 3.3V power circuit, a built-in three-axis BMM150 geomagnetic sensor,

@Calilov330000
why don't you try a simple laptop/desktop?

[Davidalan5757]

Could you unlock from UIFlow 2 the capability to code in micropython…

I am looking for all of the lcd drawing tools that were available in uiflow1.0. I was making some interactive graphics and I was drawing lines or rectangles in a loop and doing that in uiflow2.0 requires you to first drag out 100 lines in the ui builder which just is too slow. Here are the bloacks I am looking for in uiflow 2.0. How can I do something similar in uiflow 2.0

Hello,

I have some difficulties to burn UIFLOW on new devices

For ATom lite it seems to work but i get ERROR The device type is unknown! on device manager.
I dont know if it can acces to the wifi. i tried several time to unregister and burn it again, reinstall M5 burner, but it doesn't help.

It can't connect to my M5 stamp C3, maybe there is a way to make a factory reset on them?

The previous Atom and Stick set up in february still worked well, and appears with green dot on device manager. when i try to burn it now i get the "unknown type" error and red dot.

it looks like i am not able anymore to have the same atom running when i burn them today.

Did i forgot something ?

Thank you very much,

Charles

@charlesRD
i have similar issues

the Tab5 does not burn UIFlow at all!

[sgu]

When Will LVGL be integrated in UIFlow 2 ? I don't see a progress there for many months. The new devices such as Tab5 are useless without LVGL. Programming with UiFlow 2.0 and printing simple lines and squares look very old school.

Thanks for sharing the UiFlow 2.0 resources! I appreciate having a dedicated space for bugs, how-tos, and feature requests. Does anyone have tips on avoiding common firmware burning errors, especially with account binding? Also curious if there’s a timeline for the full API docs release. Looking forward to seeing how this evolves!

I recently los all my private cloud projects....is there a way to get them back from your servers?

I used UIFlow2 to devleop a simple UI demo, and I monitor the free memory with gc.mem_free(). I found the free memory reduced continiously though I called gc.collect() every loop. Finally, the UI can not update again, but the loop still was running.

[zhumingqi]

I tested more UI design. And I found that the memory leak only happens when I use image component and switch images frequently. Is that a UIFlow2.3.3 bug or my design is incorrect?

[zhumingqi]

Today, I updated the UIFlow to V2.3.4, and burned V2.3.4 firmware as well. Then I tested that image component again with M5GFX in UIFlow 2.3.4. But the issue still exists. After I switch two JPG pics with one image component for sometime, the memory will reduced continiously. Finally, the system will break out. And I try to use gc.collect() after every drawImage(), but it's not useful.
Here is my design and python code:
import os, sys, io, gc
import M5
from M5 import *

ImageSwitchFlag = None

def GcCollectAndPrint():
global ImageSwitchFlag
gc.collect()
print(gc.mem_free())
pass

def btnA_wasClicked_event(state):
global ImageSwitchFlag
if ImageSwitchFlag == 0:
M5.Lcd.drawImage("/flash/res/img/RotaryBGBacklight.jpg", 0, 0)
GcCollectAndPrint()
ImageSwitchFlag = 1
elif ImageSwitchFlag == 1:
M5.Lcd.drawImage("/flash/res/img/RotaryBGBT.jpg", 0, 0)
GcCollectAndPrint()
ImageSwitchFlag = 0

def setup():
global ImageSwitchFlag

M5.begin()
Widgets.fillScreen(0x000000)

BtnA.setCallback(type=BtnA.CB_TYPE.WAS_CLICKED, cb=btnA_wasClicked_event)

ImageSwitchFlag = 0

def loop():
global ImageSwitchFlag
M5.update()

if name == 'main':
try:
setup()
while True:
loop()
except (Exception, KeyboardInterrupt) as e:
try:
from utility import print_error_msg
print_error_msg(e)
except ImportError:
print("please update to latest firmware")******
