@aTT11 said in UIFlow V2 button on screen missing:

Hello there,

my goal is to control WLED fixture via CORE2 (by a simple http requests).

Does anyone know how to add a simple buttons on a screen. Some older tuts show the button block in UI section but now it isn`t there.

Thanks in advance.

aTT

does buttons now need to be added/enabled in hardware section? left hand side of the screen below device image

@Dimi The information in step 1 is incorrect.

@robski : some time ago I made some trials with Thonny but I was not really successful.. I will git it a new try.. at least for followng the remaining space, deleting the temp.py and so on

In other tutorials, it is also happening.
I tried with Chrome and Edge browsers.
It would be great to be able to download a PDF with the class.

@MichaelKlos that’s not how it works. If you want to add more buttons using the IO look up ho to use buttons in Micropython

Hello @taunushexe

the list blocks can be used for that. See example in UIFlow2 ProjectZone: M5Dial_Get_Values_From_Tuple_UIFlow_2.0.4

Thanks
Felix

Hello @taunushexe

as @ajb2k3 mentioned only one GPIO (the second one) is used for the RGB unit. So the other GPIO can still be used as input. I created an example which uses GPIO1 as input to control the color of the three RGB LEDs in the RGB unit.

See UIFlow2 Project Zone : M5Dial_RGBUnit_GPIO1_as_input_UIFlow2.0.4

Thanks
Felix

Use the json blocks to loads and send to the file io blocks

M5Burner is made for 32 bit or 64bit X86 based system. Raspberry pi's use an arm based system and so M5Burner is not compatible.
What you are seeing is the "Factory demo" that comes preinstalled.

I set up My RPI4B to look into it and got distracted and so haven't got very far.

@ajb2k3 Ok, thank you.

in the first image, the number is red which means that the core is not connected uiflow and so unable to be programmed. uiflow programs over wifi unless you have google chrome which may have a working webs plugin.

@bighun me too! I have seen that M5Flow blocks programming has the option of configuring Bluetooth, but there are two alternatives, BLE Central and BLE peripheral. I do not know which one should be used. I have a Core2 device. I hope someone uploads some guidance on how to do it to, for example, send sensors data to another BT device.

Regards.

Alvaro

SOLVED: open your boards.txt file and add the code below...
(Windows 10 64 bit example)

C:\Users\YOURUSERNAME\AppData\Local\Arduino15\packages\m5stack\hardware\esp32\2.0.5
(you may need to make hidden folders visible in the top menu section under the view tab) Open the boards.txt file Scroll down to the m5stick-c-plus section of code listed. At the very bottom of this section add the lines:
m5stick-c-plus.menu.EraseFlash.none=Disabled
m5stick-c-plus.menu.EraseFlash.none.upload.erase_cmd=
m5stick-c-plus.menu.EraseFlash.all=Enabled
m5stick-c-plus.menu.EraseFlash.all.upload.erase_cmd=-e

Notice the way this is listed for other boards like the stick-c and do the same. You can now use the stick-c plus board listed in the Arduino IDE! You could also just use the stick-c board listed but I had errors in third-party programs.

Yes and no.

UIFlow uses micropython which runs off the controller. Arduino uses a C/C++ cross which wipes the micropython each time.

@hansdia95 I am running into problems with using button.hide() Can you please provide an example of your usecase? Perhaps I just have a syntax error. I can not find much informaiton on this other than the writeup on github (that provides little informaiotn on this)
