Description 
Reads voltage of assigned pin, HIGH or LOW.
There are 16 pins on LinkIt ONE used as digital I/O, they are D0 ~ D13 and D18/D19, particularly D18/D19 are shared with Wire/I2C. 
Sets assigned pins to high voltage (3.3V) or low voltage (0V).

Sets up modes for assigned pins.

LinkIt One supports 3 pin modes:
  • INPUT mode is used for reading voltage (HIGH or LOW) or sensor. In INPUT mode when the circuit is at high impedance, similar to serially connecting a big resistance in the circuit, the pin can read accurate voltage value. However, this pin may not have enough voltage to activate peripheral devices, e.g. LED.
  • INPUT_PULLUP mode is similar to INPUT mode, used for reading... more
