## NAME

airspy\_gpiodir - reconfigure GPIO Direction

## DESCRIPTION

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

## SYNOPSIS

**airspy\_gpiodir**

## OPTIONS

- \-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

  ## Examples

- \<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
