Overview

What it does: Robotheca's summary

  • Provides the libpigpio C library for direct GPIO access from programs on the Pi.
  • Runs the pigpiod daemon, which exposes socket and pipe interfaces to the GPIO.
  • Includes the pigs command for socket access and the pigpio Python module.
  • Offers C client libraries libpigpiod_if and libpigpiod_if2 for talking to the daemon.
  • Lets non-Pi machines reach the daemon over the network via a remote build.
  • Installs a pig2vcd utility and man pages for the tools and interfaces.
