-n, --pin_no <n>: set pin number<n>[0,31] for subsequent read/write operations

-r, --read: read port number/pin number value and direction specified by last -n argument, or all port/pin

-w, --write <v>: write value specified by last -n argument with value<v>[0,1]

-s [serial_number_64bits]: Open board with specified 64bits serial number.

EXAMPLES
hydrasdr_gpio -p 0 -n 12 -r # reads from port 0 pin number 12

hydrasdr_gpio -r # reads all pins on all ports

hydrasdr_gpio -p 0 -n 10 -w 1 # writes port 0 pin number 10 with 1 decimal
