@robski said in M5StickC Plus 2 Official Arduino Samples Not Working:

does your stick loads ok with latest M5Burner firmware? Is user demo from M5Burner works? I can confirm that arduino M5stickCplus2 examples do work as had them in recently. Display, IR, Rtc, Battery, IMU, I've used Arduino 2.3.2, be sure you pick M5Stick Plus2

The two official images "M5stickCplus2 UserDemo V.0.1" and "UIFlow_StickC_Plus2 V.1.13.2" work correctly. I have also tried other custom images dedicated to the Plus 2, but the only one that boots correctly is Marauder.

All sketches executed from Arduino 2 do not boot, and the screen does not turn on. I suspected some power management issue or something related to the LED, but I cannot explain why the demo is working in that case.

I downloaded the latest M5Burner tool. What you mean with M5Burner firmware?

@felmue thank you for making me aware of that thread! The information contained within worked like a charm!

Maybe this solves your problem ...

class StaticClass { private: int myContent; public: StaticClass(int v){myContent = v;} void printout(){printf("%d\n",myContent);} }; class TestClass { public: //StaticClass myClass = StaticClass(42); // With C11 StaticClass myClass; TestClass() : myClass(42) { } void doit() { myClass.printout(); } }; int main(void) { TestClass tc; tc.doit(); }

@abraxas My Pleasure!

@brainzilla I am not familiar with Platfomio, but the info you need is here:

Hello guys

please see my comment here for a possible explanation and solution.

Thanks
Felix

Thank you. your help was very precious.
now it works great.

Hello @LukeS

I don't think the RGB LED has been integrated into M5Unified library for M5AtomLite. Even for M5AtomS3 the code for the RGB LED is kind of outside M5Unified library, e.g. in utility/LedDisplay.c.

All I can find in M5Unified is the GPIO definition for the RGB LED for different M5Stack devices. However I don't think they are used.

For M5AtomLite the RGB LED GPIO is (re-)defined and used from here.

And for M5AtomS3 it is (re-)defined and used from here.

Thanks
Felix

and when I try to test 100x by putting my finger... I have Add user result: 0 but the chance is 1/100. So could it be the fingerprint unit is broken?

@lukevancelave The rtc (Real Time Clock) demo is very good and you can modify it as you like or use it as an example for your unique project.
see here!

I already tried but without any results, i have a ST7789V, with the TFT_SPI library it works well but not with the M5Stack library....

@casascius Interesting. In my case I'm using real certs from my cloud and it works. I don't know how a DNS name would work outside of localhost names.

My main issue stated above was that I want a connection to stay open, and I wasn't able to figure that out.

thanks.

Same problem, Same solution (with Platformio)

Do they work if you write the UIFlow firmwares to them using M5Burner?
Are you programs actually supposed to display things on screen?

Hello @Steve1

I had success with the following converter settings.

0_1704017737289_IconConvert1_20231231.png

0_1704017750382_IconConvert2_20231231.png

This creates a array size of 8192 - same as the stock icons and displays correctly using the DrawIcon() function from the Weather app.

// array size is 8192 static const uint16_t IconCloud64x64[] = { 0x0000, 0x0000, 0x0000, 0x0000, 0x0000,

Note: I had best results converting jpg using above converter. (png did not work for me and always created an all zero array.)

Thanks
Felix

Did you get it sorted?
I started to post the formula, but I realized that you need to edit the application. I say “application” because it is confusingly written in an advanced, professional C++ style, not the fun Arduino IDE style where everything is spelled out and you just edit the line.
I mean: the loop is empty. (!)
I don’t have a ePaper to try it.
