I'm not sure whether anyone else is having this issue but my Core S3 keeps saying:

Traceback (most recent call last):
  File "m5ui/port.py", line 40, in timer_cb
KeyboardInterrupt:

I have tried python code on UIFlow 2 and blocks in UIFlow 2 but neither seem to work. It seems that with no blocks in the loop the Core S3 works fine but with a loop block and something inside it then it just crashes with that error.

That was the code that hasn't worked.
Any help much appreciated,

@MurzikYEET I think that you cannot do this if you want the firmware to run while the device is on. The way all computers work is they load the program into RAM and then run it from there. The firmware just tells the computer what to do (in this case, open boot the device and then run the python file).
I believe you can't flash two sets of firmware from M5Burner anyway because each time, it erases the whole device before starting again.
With esptool the same applies. It can't load firmware into the RAM. What it does do is load the stub loader which helps the device and esptool install faster.

However there is a way to do it. I myself am not familiar with it but I believe that you can create OTA slots that store firmware in different slots on the device and then you can boot into different firmware.
Here is documentation on OTA: Espressif Docs
Hope this helps,
RPi

@MurzikYEET Use the link to the Burner: https://docs.m5stack.com/en/uiflow/m5burner/intro
Then select and download the version for your computer.
Run the app.
Select the M5Stick Plus 2 from the left side bar.
Select the top firmware (official) and click download then burn.
If required, sign in and then configure the settings before waiting for the burn to finish. Then try on UIFlow 2.0 again.
Hope that helps,
RPi

@RPI25 It's fine. I have a Core S3 now so I don't need to use my Core 2 so much.
Thanks for trying,
RPi

@MurzikYEET I'm not sure as google translate may have got the translation wrong but have you tried the offline app?
M5Burner
Google Translate: Я не уверена, возможно, Google Translate перевел неправильно, но вы пробовали использовать приложение в автономном режиме?
Hope that helps

@sssouthpaw Yes I think the only way to do it is to copy the python file and then paste it into Thonny or VSCode before uploading through the file manager in the UIFlow terminal to get the python file on the device.

If you feel like the canvas method is too much effort - especially if it part of a larger project or you prefer M5GFX - then here is a working switch in M5GFX:

import os, sys, io

Switch2 = None
Switch3 = None
Knob = None


state = None
touch = None

  global state, touch, Switch1, Switch2, Switch3, Knob
  state = 0
  Knob.setCursor(x=145, y=119)
  Switch1.setColor(color=0x999999, fill_c=0x999999)
  Switch2.setColor(color=0x999999, fill_c=0x999999)
  Knob.setColor(color=0xffffff, fill_c=0xffffff)

# Describe this function...
def On():
  global state, touch, Switch1, Switch2, Switch3, Knob
  state = 1
  Knob.setCursor(x=174, y=119)

  Switch3.setColor(color=0x33ccff, fill_c=0x33ccff)
  Knob.setColor(color=0xffffff, fill_c=0xffffff)


def setup():

  M5.begin()
  Widgets.setRotation(1)
  Widgets.fillScreen(0x222222)
  Switch1 = Widgets.Circle(174, 119, 14, 0xa4a4a4, 0xa4a4a4)
  Switch2 = Widgets.Rectangle(145, 105, 28, 28, 0xa4a4a4, 0xa4a4a4)
  Switch3 = Widgets.Circle(145, 119, 14, 0xa4a4a4, 0xa4a4a4)
  Knob = Widgets.Circle(145, 119, 14, 0xffffff, 0xffffff)

  Off()


def loop():
  global Switch1, Switch2, Switch3, Knob, state, touch
  M5.update()
  touch = M5.Touch.getCount()
  if touch != 0:
    if (M5.Touch.getX()) >= 131 and (M5.Touch.getX()) <= 188 and (M5.Touch.getY()) >= 105 and (M5.Touch.getY()) <= 133:
      if state == 0:

      else:

I have tried to recreate your image here in this code.

    canvas0.draw_arc(155, 75, 50, color=0xc0c0c0, opa=255, width=15, start_angle=300, end_angle=240)
    canvas0.draw_line(155, 20, 155, 75, color=0xc0c0c0, opa=255, width=20)
  else:
    canvas0.draw_arc(155, 75, 50, color=0x33cc00, opa=255, width=15, start_angle=300, end_angle=240)
    canvas0.draw_line(155, 20, 155, 75, color=0x33cc00, opa=255, width=20)

@Amani4791 As far as I can see, using a Core S3:
When I use M5UI I get the same results: the picture loads slowly.
With M5GFX: There aren't any touchscreen elements. So to have a switch, you would have to make one custom.
To do what you are trying to do, I would recommend using a canvas and a switch from M5UI and just manually creating the shapes in the canvas using code because that will make the draw process on the screen much faster.
Hope that helps,

I was trying to use the IR Unit with my Core S3 in blocks (UIFlow 2.4.0) and it keeps saying there is an invalid timer time. On Port B, with just the Init block and/or the send block, it works fine. No errors. But when I try to receive data, it just brings back the timer error:

Traceback (most recent call last):
