I've got a 60 led neopixel skinny attached that I know definitely works because I have another Gemma that when connected is working fine... but when this Gemma is connected the strip just goes solid white. I've tried attaching wire to the connector pad, removing solder, and it's just not happening.
I am able to upload BLINK via usb and it is working. I have some strip tests and other sketches but I am pretty positive the connection to the pin is
ok so what I'm hoping I can do is reassign the A1 or D0 pins to send the digital data to the LED strip.
I found this: https://learn.adafruit.com/introducing- ... rduino-ide
it seems like pinMode() & digitalWrite() & digitalRead() should help me somehow but I don't know how to use it...
so far, I have this at the top of my strandtest sketch:
Code: Select all
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an input.
pinMode(INPUT);
}
thanks and cheers
