@robski while waiting i bought a new display in case that is the problem.

Hi.
Have you tried reading bytes from the GPS and displaying them on a serial monitor as they arrive as below, just to show you are getting data (if the serial setup is incorrect you should still receive data but it will be gibberish):

// Serial is the serial monitor
// Serial1 is the GPS data

int intChar;
char charChar;
intChar = Serial1.read();
if(inChar != -1){
charChar = (char)intChar;
Serial.print(charChar);
}

I have been using the M5Stack GPS v1.1 and it was set to 115200@7N1, not the advertised 115200@8N1 so might be an issue there (I got gibberish at first)

Finally my M5Stack GPSv1.1 works fine with an Adafruit Itsy Bitsy 3v controller and an ESP32S3 based controller but not with the Seeed Wio Terminal. With the Seeed Wio Terminal I get nothing at all - no gibberish, absolutely nothing. It's as if the signal is not there (but it is !!).

Hello @jhfoo2

well, in my experience and with my M5PaperS3 it takes a couple of readouts (e.g. M5.update()) until the return value from the touch controller goes back to 0.

Please let me know if you find a more elegant solution.

Thanks
Felix

Starting with UIFlow is a good choice but there are issues:

If you need something that is not included in UIFlow then you will stuck or need a complicated workaround If the UIFlow Website is down you cannot work with As it is a interpreter language (micropyhton in the background) don't expect too much calculation speed! complex programs can become confusing

There are also benefits:

very easy for a quick and (not so) dirty proof-of-concept easy to understand for beginners

One of my first programs was a TVOC logger with a remote display:

Data transfer from the stick to paper by ESPnow. It took me around 20min per device to program where the most time wasted to design the screens and understand how ESPnow works.

Another funny project was two sticks who send each other a simple message of a counter value by ESPnow showing the value on display, play a beep sound, increment the value by 1 and send it back. The other beeps as well, increment and send it back and so on... this was to test how fast it can run and how far the wireless ESPnow connection work.

For more complex programs I prefer the Arduino environment.

it runs ON MY OWN computer so i am not dependent on the UIFlow cloud systems and website more complex programs possible without loosing overview many Arduino libraries running out of the box much faster program execution / calculations than on micopython / UIFLow the web is full of examples need a bit more programming skills but still possible for beginners

At the end I used switches and it works.

@skyflyer said in External 1S LIPO on M5Core2 BUS PIN1 and PIN30?:

I tried to find information about it, and want to confirm that it is OK to connect the external Lipo battery to pins 1 and 30 on the "BUS expansion port"? And that the battery will be charged when connected to the external USB power?

If you look at the schematic you will see that pin30 on the bus and VBAT (on the lipo connector) are the same. So yes, you can replace the internal battery with an external one with the same voltage!

@skyflyer said in External 1S LIPO on M5Core2 BUS PIN1 and PIN30?:

And I don't need to remove the internal 500mAh battery, since they would be connected in parallel anyhow?

Do not simply put rechargeable batteries in parallel. Disconnect the internal one.

You can have batteries in parallel but.. at a minimum you need some diodes to prevent them back-charging each other, have a look online where there is a lot of info about this.

@robski If I set them manually in the GreenSwitch and whiteSwitch it works fine

Hello @Wambo6000

maybe you are hearing what's described on the product page here: "Abnormal Device Noise".

Thanks

I took a closer look and compared M5StampS3A vs M5StampS3 BAT and I must say that it is not possible to do any piggyback for pin mapping at the M5StampS3A level since ESP32-S3FN8 vs ESP32-S3-PICO-1-N8R8 have differences in the number of GPIOs (6 pins error), see the difference table below:

So it only remains for M5Stack team to upgrade M5StampS3A for 2/8 PSRAM, i.e. have M5StampS3B version.

In addition, the following screen snippet shows two possible suggestions how the 2x9@2.54mm pins can be assigned.

I also tried changing the following settings:

frame_buffer_count: 2 frame_buffer_location: dram

and

priority: 1000

lowered resolution to 320X240.
and

External_Clock frequency: 8MHz

All without success.

@harrietteytlxv222 did you read my post from Feb 12 (follow the link)? Do you use the appropriate emissivity value for your surface?

@himlol is comport detected in M5Burner?
do "erase all" option then pick up correct firmware M5StickC, M5StickC+, M5StickC+2

@GusBel use M5Burner and load fresh firmware

@flyingjeepman on/off button on? is M5Burner detecting com port when usb is connected?

Hi Alex,

If I am understanding your question correctly you should be able to find the Demo within the M5Burner application?

Hope this is what you are looking for?

Thanks-Brian

@HappyUser Found it in the Meshtastic app on OSX under device settings. Btw, IOS app does not allow for tcp connections as it seems.
