The Airspy is a tiny and efficient software defined radio receiver.
WARNING this tool reconfigures AirSpy GPIO Direction IN/OUT and can destroy GPIO/MCU in case of mistake




-p, --port_no <p>: set port number<p>[0,7] for subsequent read/write operations0
-n, --pin_no <n>: set pin number<n>[0,31] for subsequent read/write operations0
-r, --read: read port number/pin number direction specified by last -n argument, or all port/pin0
-w, --write <v>: write value port direction specified by last -n argument with value<v>[0,1]0
[-s serial_number_64bits]: Open board with specified 64bits serial number.0


<command> -p 0 -n 12 -r # reads gpio port direction from port 0 pin number 120
<command> -r # reads gpio direction all pins on all ports0
<command> -p 0 -n 10 -w 1 # writes gpio direction port 0 pin number 10 with 1(output) decimal0
