Thank you .. sometimes it´s just my hope to get an easy solution running and waking up in the middle of to many micro learning.

I bought the scale kit and am surprised that my smartphone should weigh only 21g. But it is 210g. Does the scale really output only 10g accurately and I´ve tp multiply the result with 10?

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.

Hi there .. I tried to download the latest M5Burner to my Mac Ventura and I´can´t run the tool because of an message:

"m5burner cannot be opened because the developer cannot be verified." (because it can be malware)

Is there an easy way to work with XML as Map?

I request an webservice who can only respond with an XML schema. Now I want to use this in my UIflow. There is only a good way to convert JSON to an Map.

Do anybody know a quick way with "execute" or some other simple "offline first" way?

@bmtd111 You have to define the wifi connection in your scetch too .. because the configuration of M5Burner is just used during connection with the computer via USB.

For this connection is Wifi needed .. and this step is missing in your flow. Just my first idea. During the connection via USB there isn´t a connection via wifi needed.

Hello ... I have a conceptual question. I want to connect about 20 controllers with different tasks without internet in one vehicle.

Logically, each controller should receive all requests and then pick out those that are relevant to it. And each controller should be able to send such a broadcast.

What is the most efficient and robust method in terms of energy consumption? Radio must be used. Most (or all) controllers are ATOM Lite. UIflow has to be used.

Option A: The simplest case would be to connect via WIFI, where everyone is connected and then communicates via MQTT. This requires a central router and broker. But WIFI is supposed to consume a lot of energy and all devices have to be online all the time.

Option B: ESP NOW is great for networking two controllers in one direction, but such a bidirectional mesh is quite difficult to establish stably in the latest version.

Option C: What would be even better?

I found in UIflow no "Power" block for turn off. This can be done with the "Exec" and "machine.deepsleep()". But this is only for the Core and not for the "GoPlus2 Module". How can I turn everything off?

@felmue this worked in my case .. longPress and wasReleased

@felmue said in UIFlow .. multiple Weight Sensors with PaHUB?:

in the weigh unit is not an I2C devic

Thank you .. it´s a little bit confusing but I will use multiple independet setups with ATOM Mini.

For now it´s nearly the same like before and maybe the biggest innovations are in restructuring the UI and "under the UI".

There is still no multiple views feature to make the display more usefull with the UIFlow?

In UIflow I can´t connect multiple "Weight Sensors" with the "PaHUB". Most of the other sensors doesn´t have this issue. How can I connect multiple "Weight Sensors" to my Core while using only the port A?

Thank´s

For me, the issue is resolved, but not quite with an eye to the future. I had the UI Flow IDE on the desktop 1.9.5 ( there is unfortunately not newer) and on the Atom Lite I had the 1.11.0. Thereby it came to incompatibilities that the EspNow in the newer variant works quite differently. BADLY.

I will try the " craft approach ". The LED driver does not provide stable 12V, as it can be between 12 to 14.5V in a camper. And with your recommendations for diode and capacitor.

@holofloh said in Read PWM Signal from Device:

I put a small simulation where you can play a

Sorry for that and thank´s for your feedback. I missed a "k" before Ohm. This is what I´ve tested.

Is this nearly the same https://shop.m5stack.com/products/adc-unit or what is the difference.

I started with an ATOM Matrix and used very simple EspNow Communication. Then I adapted this to the smaller ATOM Lite but the easiest things won´t work.

UI Flow + ATOM Lite + EspNow

The serial monitor results in:
Traceback (most recent call last):
File "main.py", line 13, in <module>
TypeError: function takes 1 positional arguments but 0 were given
MicroPython 3a9581b5a-dirty on 2022-12-08; M5Stack with ESP32
Type "help()" for more information.

This is the code which works filne with my Matrix and not with the Lite

from m5stack import *
from m5ui import *
from uiflow import *
import espnow
import wifiCfg

addr = None
data = None
dataObj = None

wifiCfg.wlan_ap.active(True)
wifiCfg.wlan_sta.active(True)
espnow.init()

espnow.broadcast(data=str(((str('OnAir-') + str((espnow.get_mac_addr()))))))

It hang up with the espnow.init()

Okay .. I tried variant B and it works well with just two resistors .. in my case 100 and 27 Ohm. To get a realy clear 0..100 signal I measure the PWM signal and the source voltage 12-15V. This way I can better match what my dimmed 2.6V really is.

How to read a PWM signal from a LED dimmer? The dimmer works on a 12V LED and I want to dim other - remote - LEDs with this value as well. Therefore a M5Atom or M5Core is connected to the dimmer and a PWM kit connected via EspNow to the additional LED.

LED Dimmer PWM > M5Core read PWM Signal "Value" > EspNow send "Value" > M5Atom with PWM kit > LED

I use the PWM signal from a PWM kit to control a fan.

This fan gets the PWM signal as an input signal, but the fan never stops. This also happens when I use the PWM signal directly from the Atom.

Is there any way to get the fan to stop?
