I have been unable to use the web / easyloader-packer / service for several days.
Is he still working? How?

@felmue Yes confirm. this latest version library works! Here is the blink code
#include <Adafruit_NeoPixel.h>

#define PIXELPIN 2
#define NUMPIXELS 1

Adafruit_NeoPixel pixel(NUMPIXELS, PIXELPIN, NEO_GRBW + NEO_KHZ400);

void setup() {
pixel.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
pixel.clear(); // Set pixel colors to 'off'
pixel.show();
}

void loop() {
pixel.setPixelColor(0, pixel.Color(0, 0, 128));
pixel.show();
delay(1000);

pixel.clear();
pixel.show();
delay(500);

pixel.setPixelColor(0, pixel.Color(128, 0, 0));
pixel.show();
delay(1000);

pixel.clear();
pixel.show();
delay(500);
}

When will there be M5Stamp C3 programming examples? Interested in turning on the LED in different colors.

How can I prepare a .bin file for direct program recording into m5stickC (m5StickCPlus) via M5Burner?

Very very quiet buzzer sound. Like the sound of an insect. So on all 4 purchased devices.
Is this normal or a marriage? Can this be fixed?

How do I programmatically reduce the sensitivity of the M5StickC microphone? Is it possible? The sound is very loud.

this is a very useful function. Looking forward to!

How to make EasyLoader for M5StickC with my program? How to prepare the necessary files?
I am writing in Arduino and PlatformIO.

@world101 said in Knock Detector with microphone m5stickC:

@auct

Try this...

Thank you, I saw it. How to write it in Python?

Yes, you need to use a internal microphone.
How?
