Is there a reason a particular reason that the LED examples connect the current limiting resistor to GND and light the LED with a logic high state on the pin?
I'm more used to TTL open collector where the current limiter goes on VCC and you drive the pin low. Are the GPIO pins on the BBB able to provide the same current in both states? My digital logic knowledge is somewhat dated. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
