Smart ETK GPIO interface
First, please open the Smart ETK sample program, then from the left side select GPIO. In
the demo program, pins 1~10 have been set as programmable GPIO pins.
The toggles under each pin can be used to set the desired configuration.
IN/OUT: Sets whether the pin is defined as input (IN) or output (OUT).
If you set the GPIO pin as an input (IN), you can then set whether the input voltage is
high or low with the INPUT PULL UP/DOWN toggle.
INPUT PULL UP: the input voltage is high.
INPUT PULL DOWN: the input voltage is low.
If you set the GPIO pin as an output (OUT), you can then set whether the output voltage
is high or low with the OUTPUT LOW/HIGH toggle.
OUTPUT LOW: the output voltage is low.
OUTPUT HIGH: the output voltage is high.
