How do i get the characters for my region such as the pound sign £ ?

@jlp373 Hi! because of this problem i made a updated version two weeks ago. Sorry to not update it here.
Just visit https://github.com/frittna/Crypto_Coin_Ticker and download the zip archive (M5Burner_Crypto_Coin_Ticker.zip) for the easiest way.

Make sure you're holding the "G0" or "BOOT" button while plugging in the USB or clicking "Burn"—this puts the Cardputer into flash mode. Also try a different USB cable (some are charge-only), and plug directly into your PC (avoid hubs). Lastly, check Device Manager to confirm the COM port is stable and not switching. If all else fails, try flashing with esptool manually via command line.

@gachapo Thanks for persevering with this as I got my M5 to day and was getting confused lol. Without this link I would never have got it up and running so thanks for the link as that has kept me from throwing it out of the window.

For anybody else looking at fixing the issue with multiple simultaneous button presses it seems it can't be done.

Having dived into the M5Core2 source the events generated for two button presses, e.g. A & C, are press for A and move for A.
This looked like a deeper bug (since the second should have been identified as C), so going further in I found that an else branch wasn't refreshing the currently identified touched button on second press (C) in the method "doEvents" in touch.cpp (it doesn't help the code isn't documented, isn't single responsibility and has an arrow antipattern too).

Fixing that bug, so the correct button is refreshed, showed that two events together did not produce presses for A & C but instead (I assume - I'm fed up at this point) the hardware averages the presses' coordinates and declares it's button B(!) that is pressed.

If you have old Core 1 code you're porting that uses two simultaneous button presses I'd suggest changing the code to double taps of a single button instead which is the workaround I'm about to use - to remain consistent this behaviour is both on Core 1 and Core 2

More formally, I should have read the file header in touch.h earlier:

the M5Stack Core2 touch display is only
multi-touch in one dimension. What that means is that it can detect two
separate touches only if they occur on different vertical positions.
This has to do with the way the touch screen is wired, it's not
something that can be changed in software. So you will only ever see
two points if they do not occur side-by-side. Touches that do happen
side-by-side blend into one touch that is detected somewhere between
the actual touches.

The E-Ink Paper Display (EPD) on the M5Paper consumes power even when the screen is idle due to its underlying technology. E-Ink displays are different from traditional LCD or OLED screens in that they only consume power when the content on the screen is changed. Once an image or text is displayed on an E-Ink screen, it doesn't require any power to maintain that state. However, changing the content on the screen, such as refreshing to display a new image or text, does consume power.

In your case, when the EPD power is disabled, the display is essentially turned off, and it consumes very little to no power because it's not actively refreshing the content. When you enable the EPD power and the display is idle, it's likely in a state where it's ready to receive new content and is therefore consuming some power in anticipation of a refresh.

The power consumption you're observing is not necessarily a sign of a defective unit but rather a characteristic of E-Ink displays. If you want to optimize power consumption further for your low-power application, you might consider:

Reducing Refresh Rate: Minimize the frequency of screen refreshes. E-Ink displays are typically used in applications where the content doesn't change frequently. You can adjust the refresh rate to be as infrequent as possible to save power.

Full Screen Updates: Instead of partial screen updates, use full screen updates when you need to change the content. Partial updates can be more power-intensive.

Deep Sleep: Continue using the deep sleep mode of the ESP32 when the screen is idle. This will significantly reduce overall power consumption.

Optimize Code: Make sure your code is efficiently managing the display and other peripherals. Ensure that you are properly putting the ESP32 into deep sleep mode when it's not actively needed.

Hardware Modifications: Depending on your specific use case, you might consider hardware modifications to further reduce power consumption. This could involve custom power management circuitry or using different power supplies.

Hello, I realize this topic is very old but I'm trying to compile the MultiApp Advanced firmware. I'm getting several compile issues:

src/Apps/WiFiWps/WpsConnect.cpp:30:12: error: 'struct esp_wps_config_t' has no member named 'crypto_funcs'

I did clone the git repo today, so everything should be up to date. Looks like I'm missing some library?

Thanks,
Brian

For the M5FIre do this
For the m5stack fire you need to follow these steps

Remove all modules, leaving only the host Then try to lower the baud rate when burning If there are wires, you can short-circuit G0-GND before powering on the device and then power on again.!

@JNVoirol I still haven't solved the ssh issue yet so still directly logging in.

Hi Guys,

ihm new with M5Stack. I have a MCore2 and try compile this in visual code with plattform.io.

How i must use the code in Plattform.io ? If i compile the code, the device showing black screen.

Can anyone help me ?

@ajb2k3 Thank you, very helpful information!

@iamliubo May I ask you if you are part of M5Stack staff?
Not to bother you, just to understand the M5 ecosystem ;)

@M5Stack team: I am looking for any ressources / tutorials on how to use remote+ in uiflow. I do not find any project on hackster.io. please provide a test case tutorial sothat people may use the graphical interface...
Has anybody used it successfully?

@foxhound Best wish to you !

@felmue thanks for letting me know. It’s been stable for the testing but I’m yet to move beyond. I tried looking at provisioning for vets and codes but my brain is not taking it in hence the low level MP stuff.

I’m sure there will s an issue with MP but I don’t deal directly and not getting feedback from @m5stack or @IAMLIUBO

For those who have 'battery issue' with their M5Stack; please, use the 'contact now' button on any product page of our Aliexpress store to contact with our after-sale team. We will try our best to bring you a satisfying purchase experience.
