@bazman thanks!

@pandian-nano yes you’re right, thanks for the clarification!

@pandian-nano thanks a lot this is very helpful but according to the page you mention your statement saying”fstring is not supported in micropython” is not totally true.
If you refer to the page you mention you can use FString but not in all scenarios.

Example;:

print(f"{x}" "ab") # works
print("a{}a" f"{x}") # fails

FString is therefore ‘partially’ supported in micropython

Thanks anyway, now I have an official explanation ;;)

@pandian-nano thanks I have already applied this workaround but I was just asking for confirmation that f-string is not supported on the StickCPlus with uiflow1.

Hi there,

I have a script which is using string literal, something like:

name = "john"
print(f"My name is {name}")

This code is not working in UIFlow v1 with an M5StickCPlus
I also tried directly in the REPL and I have the same error.

Can someone please confirm this is not supported (by UIFlow? Micropython version of the StickCPlus?)

Thanks
Eric

@gavin67890 in case you're still interested, I have resumed my work on the M5StickC plus and the KY-022 IR receiver.
So far I am able to load the external IR library and use the REPL to scan and get information about my IR remote buttons.

Means that it works and I can now code the UI stuff !

@gavin67890 thanks a lot for the link!

I agree it does not look much different from the current stickcplus. Also I see it was supposed to be launched end of July… let’s wait and see

Hi there,

Sorry I just need a confirmation: Alpha-26: Is it right built-in Infrared is not (yet, hopefully) supported on the M5StickC PLUS? I cannot find IR in the integrated hardware menu.

Also, I have noticed support for M5StickC Plus 2 , is it an upgraded M5StickC Plus not out yet? I am very interested ;)

Thanks for your answers!

Hi Gavin,

I moved on to some other projects and did not have time to come back to this one yet (even though I would really like to achieve something with IR + M5StickC+).
I found a 3rd party IR library on the internet but it was quite a challenge to integrate it to the M5 ecosystem....work in progress but not much time at the moment.
I'll keep you posted as I resume my work on this.

Hi all,

I am generally coding with VSCode / PIO in C but with a M5StickC+ hanging around I wanted to develop an idea with a small battery powered device to replace some of my tools
The idea is to run multiple programs on the stickc to do various things like measuring distance, send IR codes, identify IR from any remote control etc...
In fact I have already built a small project with an arduino and an IR receiver (KY-022 module) few years ago able to recognise a big amount of IR standards (NEC, SAMSUNG, etc...) and their HEX/DEC code using an easy library found on the internet....it is working like a charm and I have been able to recognise the standard use for all the remote controls I have tested so far.

Well long story short I'd like to replace it because it is bulky, 9V battery powered, using old fashion LCD display etc...
This was the opportunity for me to start looking at UIFlow.

I could get ready quite fast and I guess I understand now most of the features.
However I have been VERY VERY disappointed by the limited (to say the least) features....
I know the Stickc+ only has a Tx IR, not Rx but still, this is a joke, only limited to NEC standard and that's it? or I am missing something.

Anyway I purchased the IR Remote module from M5Stack and same joke, on the IR Rx you can only acknowledge a signal has been received...and it is not working with any remote I have tried (not a range issue, I was 10cm from the module)...no possibility to change from NEC either....
This module is totally useless...at least with the default UIFlow

Now I am trying to come back to my trusty KY-022 plugged on StickC+ GPIO but I need external libraries.

I understand you can load external lib.py files on the stickc+ memory and load them with Execute module.
Then I guess I should create some Custom blocks to include the code from the lib and extend the IR functionalities?

Do you think this is the right way to do it in UIFlow, does someone have any experience with external micropython IR libraries in UIFLow?

Thanks a lot!
Eric

Great! looking forward to it!

Nice! Do you have any idea which topics you'd like to touch on for the next volumes?

I'm struggling with edgline but just realized the code which is automatically generated is not compatible with LVGL 8.x, only version 7.
Looks like they have not updated the tools since a while, not even sure if they still want to maintain it.
I am going back to old school manual coding...I don't mind writing lines of code but I am bad at designing UIs and EdgeLine seemed to be my savior (but not anymore unfortunately)

@jackrazors Thanks for sharing!

@got thanks, I will for sure ;)

Great, I'm glad it works for you!
I don't feel I did much to help but anyways here is my GH account: https://github.com/erich74
At the moment I juste have a couple of private reps but I am planning to add public stuff when I get more used to M5Stack devices as this is becoming my main development/iot device platform.
I will come back to this thread as I will probably need some help when I progress with my current project ;)

@macsbug you're right, I did mention using TFT_eSPI instead of M5.Lcd only for portability reason.
I would like to create a set of sample files that I can use with any display and not only with M5Stack devices.

Hi Pierre,

Sorry I don't feel I did much for you but my (real) work is really taking much of my time (even what is supposed to be my free time) and I wish I could have spent more time working this out with you.
In any case my offer still stands, I can help you building up a simple template with comments for people to get started.
I already spent much time on it and I believe I have understood all the basic concepts .
As already said, now i need to go one step further with event management.
Also I am quite used to code in C (this is the language I started with a loooong time ago) I am not an expert but at least I can understand the most of what I do :)
Btw a good platform that I have adopted now since several months is VSCode + PIO...Very neat combination!

Honestly I started off reading the LVGL online help and even though I am still learning I did not have much problem making the lib work on the Core2.
However I spent some significant time before understanding the whole concept (probably because I am getting too old :) ) and you seem to be way more experienced than me so you will make it work quickly :)

My GitHub project is private (because it might end up being commercially used) but if you want I can extract the minimum code I used to display something if it can help and make it public.

By looking at the error (If I remember I got more or less the same) this looks like invalide pointer / memory allocation.

I realized that just initializing everything for LVGL to work is a real pain (when you've never played with it) but after you've understood the basic concepts it comes much clearer.
At this stage all basic things are working fine I am now moving on to Event management (button press, sliders move etc...).

Btw you can also have a look at the EdgeLine application which is a kind of LVGL companion allowing you to WYSIWYG to C/Python code automatically for you. I am very bad at designing UIs so I am starting using it for my project and it can also help you understand the code which is generated.

@got said in How to run LVGL on M5Stack:

lv_conf.h

btw as you've already guessed, you have to tweak the lvgl_conf.h file otherwise it won't probably work out of the box
