Yes this works .. its in the tab "Privacy and Security" and there I had to switch from "Appstore and verified developer" to "Appstore" and then open the M5Burner again and confirm "Still open". Now it works on every start.

Okay ... that falls then under "teaching money" and super stupid. Happens when it should always be done quickly on the side.

I would love to see the BLE support written on the box useable in the software. That would be a really great feature because currently I connect to the phone via wifi and that's a disadvantageous way. My dream would be "PWA > BLE > Atom".

I will try the "ignore empty lines" method.

It feels random because of .. first try line 162, second try line 198, third try line 67 and finally it´s working without an issue .. and I don´t change anything in the meantime.

I´m using the version 2.0.3 for UI Flow and the firmware on my Atom S3 Lite. I´ve now an little bit complex part of script designed with the graphical interface. If I now send this to my Atom I get random errors for syntax. But if I send the same code several times I get random line references and also running the code without issues.

How can I now make sure, that my code is correct and starts every time? Which lines of code are mentioned because sometimes the reference is an empty line of code.

One more try .. I connected only the PWM pin 5 from the Atom with the PWM kit and powered the Atom via USB with no output. But from the layout it should be enough to have only the PWM signal?

And one more thing. If I power the Atom S3 via an USB cable it´s working. Can this be an powering issue?

If sombody want´s to test it .. https://uiflow2.m5stack.com/?pkey=c091fb79f13c4a1f956c407157c7e8fe .. Atom S3 Lite on PWM kit

Hi .. if I run my current code on my M5Dial there is an issue. I got an "invalid syntax" but in line 41 is nearly nothing incorrect.

41: mqttMsg = None

Traceback (most recent call last):
File "<stdin>", line 41
SyntaxError: invalid syntax

If I change the order of the lines, I get the same issue but for a different line and the old one is still there before the new one.
41: TempKlima = None

I think there is nothing wrong with these lines and I´m looking at the wrong place of my code.

I tried now several devices and something is special with this combination. Sometimes it´s working for several seconds and then there seems to be a power cycle and it´s starting again. But Atom S3 Lite + PWM Kit never works well for a while. Super frustrating .. nobody else with this behavior?

Just to make clear .. the following code is only working with the Atome S3 and NOT with the Atom S3 Lite. Both in combination with the PWM Kit.

import os, sys, io
import M5
from M5 import *
from hardware import *
pwm5 = None
def setup():
global pwm5

pwm5 = PWM(Pin(5), freq=20000, duty=512)

M5.begin()
def loop():
global pwm5
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")

Hi there, I have an Atom Lite shipped with the PWM Kit and this is working well for a while. I use the Pin 22 for controlling the output and I use the UIFlow to program the device. Because of the missing support of BLE with UIFlow and the missing support for UIFlow2, I want to start the same thing with an Atom S3 Lite. It´s marked as compatible and I use the Pin 5 for controlling the output. BUT I can just use an single step flow to just init PWM with 50% duty cycle and it´s just flickering for short and nothing more.

What did I wrong?

If I use the same Atom S3 Lite with this software to directly control an FAN with PWM input, everything worked well.

Btw .. I tested this on two different Atom S3 Lite and two different PWM Kit with the same behavior. But with an Atom S3 and the same flow, it worked fine.

Is there any information until when UI Flow 2 is supporting the Atom Lite?

Surprise ... in the old UI flow 1 it is exactly as I had hoped. You add the unit and can then build something directly with it. This shows that some new components are better supported in the old UI flow than in the new UI flow 2.

It's okay for me and my current requirements, but it doesn't give me a good feeling. Which platform should I rely on now if everything is poorly documented and randomly supported?

Hi .. I have a Scale and QR part to connect via I2C with an Atom S3 or Core2 and I will use UI flow 2 for this but they are both not in the list and I don´t found any documentation for I2C for UI flow 2. Is there somebody who can help me with this?
