81
(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.

0 1 0 0 - 0 1 0 0
