Hi, My name is Adam and as the M5Stack community grows everyday I thought I would be interesting to see who is active here and what part of the M5Stack environment is interesting to you the most.

For me is has to be UIFlow as it is the first environment that has allowed me to work with the ESP32 family without major difficulties.

I’m currently working on a UIFlow handbook and some STEM projects.

I have shared a little about me, is anyone else willing to join in?

Welcome, It is now 2024 and in China it is the year of the Dragon.
This year's challenge is to use M5Stack products in the garden / greenhouse / farm / or any other place where you may grow things.

M5Stack product a wide range of products for electronic development and design but I have yet to see much use in the agricultural sector.
Throughout 2024 and 2025 (dependent on the seasons) I would like to see what you can make or how you use M5Stack Products to improve or enhance gardening and growing.

There is no formal registration or signup and the only rule is that wherever possible only M5Stack products must be used.
This doesn't mean that only M5Stack products must be used as things like MQTT / IOT servers are required for collecting data or external weather stations for taking reading are acceptable.

The whole point is to use electronics in the garden and have fun.
I can't wait to see what you come up with.

When you install UIFlow and finish setting up the wifi, the API key will be displayed on the screen along with the mode and the network you have connected the device to.

HY2.0-4P or grove connectors,
VH3.96 for the orange connectors.

@chpaaa1 You will need to rebuild the firmware from scratch as the ESP32's in the Echo and S3 are not the same.
There are enough hardware differences that make them incompatible.

Grove is a standard of cable design created by seedstudio as you have noticed.

It uses a 4 pin JST-PH connector with a 2mm centre between pins.

There are 2 main cables latching and non latching. Latching is used for sensors and actuators that need to be connected to controllers where as non latching is needed to plug into the controller (M5Stack/ SeeedStudio Wio).
You just need to snip the latch off of one end of the cable to plug into controllers or devices tat have the clip covered.

There are also 2 varients of the cable on the market one has the colours Black, Red, White, Yellow, and the other has Black, Red, Yellow, White.

There are however additional Seeedstudio/M5Stack cables that are
Grove 2 Grove,
Grove 2 Stemma,
Grove 2 Dupont Male,
Grove to dupont Female.

You download M5Burner,
Connect the M5Stack,
Select the USB port,
Download the latest firmware version for the M5Stack,
Erase the software on the device with the erase button,
Write the UIFlow version to the device and wait for it to restart,
Close M5Burner,
Open wifi manager and connect to M5 wifi device,
Open web browser and goto the IP address on the screen,
Select your home wifi and type in password (spaces are not allowed in wifi SSID),
If you connect succesfully, the API with be shown on the screen as it tries to connect to the UIFlow web server.

Burning UIFlow2.X Alpha to the AtomS3 https://www.youtube.com/watch?v=2w85U4XwGj4

Where previous ESP32 based products only had one level for writing firmware (I will call this user Space Firmware) the ESP32S3's used in the S3 generation of products use a different access method more akin to the Raspberry Pi Pico based products.

What this means is that there are two USB Drivers needed to be installed in order to fully access and write Firmware to the ESP32S3 series.

The first driver is the JTAG/Series Com driver which allows firmware to be written into the user Space Firmware area and the second is the low lever modem access driver which allows access to the Bootloader level and is also used for making the ESP32S3 devices into HID devices (keyboards, mice, space knobs and joysticks).

Firmwares like the flipper/Maradar makes use of the serial/usb port blocking them from being able to burn new firmwares requiring the need to access the lower level boatload mode ignorer to wipe/burn new firmware.

Through my experiments I have discovered that on windows and linux based machines I have not been able to install the second (modem) driver resulting in the esp32S3 unable to be put into Bootloader mode. Bootloader mode access is shown on the S3 generation models by a green LED lighting up after 5 seconds.

I am still looking into this but I need a new Windows based computer to experiment.

This isn't an issue with the M5Stack products as it works perfectly on MAC OSX based machines and some other Windows/Linux machines used by the more Knowledgeable members. for the moment DO NOT USE the FLIPPER/MARAUDER based firmwares otherwise you will need to replace the StampS3's to continue use.

The Precompiled binary is in the M5Burner firmware burner program along with other precompiled firmwares.

@liujinyou Did you burn the correct version of UIFlow for your specific cardputer?
Did you erase the cardputer first before downloading and burning the latest cardputer UIFlow2 version?

@nnazar EZData was only designed for testing MQTT services.
I recommend getting something like the CoreMP135 or the CM4 stack, and building your own private dedicated MQTT server on that.

@gantini The sensor is a capacitive sensor and so the higher the reading the lower the moisture level.
These are superior to the resistive sensors that rot easy but work the same way.

@twigs said in Using M5Stack for Custom Signage Displays – Need Advice:

Hey everyone, I’ve been exploring M5Stack modules for a custom signage controller project—curious if anyone here has experience using UIFlow or MicroPython for real-time display updates?"
"Also open to suggestions on the best units for LED or TFT screen integrations—appreciate any tips!

For a start, Micropython is not a realtime language, it is an interpreted language.

The biggest issue for signage is that of memory and ram, the bigger the sign, the more the memory is required.

@m1cr0lab said in Unable to connect with M5Burner:

@robski @ajb2k3
Thank you for your answers.

I reinstalled M5Burner...

But when I went to the online UIFlow 2.0 application, I realized that, like an idiot, I was using my username instead of my email address to log in.

Now everything works normally. 🙂

Sorry for the blunder... but I'm guessing I'm not the last person this will happen to 😁

Cheers,
Steph

ROFL,
I think most of us have done that at some point!

@m1cr0lab try deleting M5burner and reinstalling, failing that it could be an issue with the server

@zakk3456 doesn’t need to be selected from the device software list?

@Shanks-0
Port B is generally a no as one of the pins is normally input only

@GeorgeR Have you tried emailing M5Stack?

@StefanM5 said in M2StickC Plus2 UIFlow:

Ich konnte UiFlow auf mein M5 brennen und mit M5Burner wird er gefunden. Aber mit UiFlow für Windows 11 sagt er das mein M5 ist nicht online. Wo ist der Fehler ??

Haben Sie sich bei Ihrem Konto angemeldet und das Gerät während des Brennvorgangs an Ihr Konto gebunden?
