Hi @yellowelise are you planning on designing your own firmware? of course, when you flash your m5 device with our burner software it is flashing a .bin file a .spiffs file and a few other files, you can also do this by command line if you choose with esptool. It would be good for you to expand on your questions more so we can better help you.

Very cool! Can't wait to try it out!

First attempt at a custom PCB for the servo clone.

world101 : I saw that you posted that thread, I will be checking it since I have a lot invested in blynk and in m5stack, and having both working together for me is a huge thing!

Here you go...

@mrjellofingers

That noise is definitely related to your camera hardware or camera settings.
As you can see on the image from my post, there is no noise on the image with the camera i am using.

@ajb2k3 I don't mind. Please do it.

Thank you Very Much!

@dvd78 I think.....
If you just power it on it should autoload the program.

@an-erd said in How to use the Buzzer in M5Stick:

I tried to use the buzzer on M5Stick.
In UIFlow I used Advanced > PIN > digital write pin 26 to 1, but you don't hear the buzzer. You can feel that M5Stick "tries" to do it.

So what did I wrong? I expected to have a buffer as in a mobile phone to at least feel if vibrating or to hear a beep?

You don't do that in UIflow, you use speaker.tone(1600, 200) or speaker.sing(220, 1)

from m5stack import * from m5ui import * clear_bg(0x111111) speaker.tone(1600, 200) speaker.sing(220, 1)

or the Speaker beep and play tone blocks in the blocky mode.

Please change your title as it is misleading.
This is not an Arduino question, it is a Platformio question.

@watson said in Neopixel Experiments in uiflow:

@ajb2k3
How about your neopixel breathing project?

That's the base layer code but it only lights the Pixels in a predefined sequence.
Need to find a way to randomize the sequence instead of hard-coding the pattern.

ajb2k3, I'm using arduino IDE.

there is a small mistake in the last commands:

ampy put boot.py

that is

ampy put {{local_file_path}} # implicit remote path and name with json

and the JSON-File

yes, already answered, thanks to @simm

@farmeuhly said in PIN number and shields:

Hello, happy new year !
I'm back on my tests...

I have a lot of problems.
1 : problem for uploading sketch on the board, i should remove the "bottom" of the m5stack and bush the boot button for it to work ! And sometimes it fails anyway...

2 : I tried to stop the pins on the "bottom" with the sketch "blink" and those that work are :
0, 2, 3, 5, 12, 13, 15, 16, 17, 19, 21, 22, 26
The others (1, 18, 23, 25, 34, 35, 36) doesn't work.

3 :
I don't understand why the same simple sketch work fine on arduino uno board and don't work on the m5stack.
I put the #include <M5Stack.h>, m5.begin(), m5.update... But i have the impression that the selected pins don't work.

What i'm doing wrong ?

Because the esp32 and the mega328p do not have the same pins.
The AtMegas have defined pins but the esp32 uses a matrix of functions that can be assigned to each i/o pin.

Check out the esp32 data sheet for these functions.
