Digital output for representing logic high (1) is 5 V, and for logic low
(0) is 0 V. To set an output pin’s logic level, use the GPIO remote
command. Again, all pins (except pin 5) are represented as 8-bits
binary, according to Table 5 above. When using the GPIO
command, the decimal representation of the 8-bits binary is used.
Taking the example above with pins 8, 6, and 3 set as OUTPUT
pins, if pins 8 and 3 are to be set with logic high (5 V) and pin 6 set
with logic low (0 V), send the following command:
GPIO 68
68 is used to represent 01000100 in binary. Only pins 8 and 3 have
the value “1” to represent logic high and output 5 V. Pin 6 has the
value “0” to represent logic low and output 0 V. All other pins should
be “0” as they are input pins and thus, are ignored.
