hello,
My question is about the expansion slot of Beglaeboard-Xm rev C. I want to connect an LED (white), whose specifications I provide you below:
http://docs-europe.electrocomponents.com/webdocs/091c/0900766b8091cfb0.pdf
The pin number 2 nd current at 5V DC. Connecting the pin diode in that if I work.
But when connected to any other pin, eg the 24 (GPIO_168), the LED does not light.
I do the following:
cd / sys / class / gpio
ECHO 168> export
cd / sys/class/gpio/gpio1168
Enter echo “high”> direction
And, as I said above, the white LED does not light …
I do not know if it’s because these pins do not provide the necessary voltage, if I’m doing something wrong …
I do not know if you could help me!
A greeting and thank you very much
