  • Product COM-12656 | about 4 months ago

    Does anyone know if this could be use to record/learn a dog bark and recognize and trigger based on that?

    Weird characteristic… This board powers itself from the Rx line if power is removed from the USB-VCC pin.

    Even if R19, a 10K pullup is removed, a signal from a Yún (Yun) D{#) out (used via software-serial library) is enough to power up and maintain CY8C29466 as “ON”

    Any suggestions welcomed. I would like to be able to turn this completely OFF simply by removing power from the USB-VCC pin (5V).

    Problem…

    In the Adafruit Neopixel library, sketches / objects and their members overall work fine… Except when you try to use the class member to set a single pixel to all white:

    // Set pixel color from 'packed' 32-bit RGB color:
    void Adafruit_NeoPixel::setPixelColor(uint16_t n, uint32_t c) {
    

    And employ it on an Arduino Yun/Yún with a call like:

    Console.println("White");
    strip.setPixelColor(0, strip.Color(255, 255, 255)); // White
    strip.show();
    delay(4000);
    

    The pixel Flashes white, then goes to black (off)

    However if you change the above with:

    strip.setPixelColor(0, strip.Color(255, 255, 254)); // or make any of the 3 values so that they are not all 3 the same...
    

    Then the pixel works fine… stays (almost) pure white as possible.

    What is the library or HW bug where (on the Yun/Yún, at least) where if these three color values are the same non-zero values, it flashes that color then instantly changes to off?

No public wish lists :(
