pigg - Raspberry Pi and Pi Pico GPIO Remote control from GUI and CLI
A set of apps for Raspberry Pi GPIO Output control and Input visualization, with GUI and CLI Support for macOS, Linux (including Raspberry Pi) and Windows; GPIO CLI agent for Raspberry Pi and embedded applications for Pi Pico (USB) and Pi Pico W (USB, TCP).

- Here are two videos showing the two ways to use it, with pigglet running on a RPi shown via VNC.
You can see more gifs and videos of features here
Feature Summary
- Directly on a Pi or Pi Pico or remotely from other platforms you can configure the GPIO hardware Inputs and Outputs, controlling the level of the Outputs and view the level of the Inputs in the GUI.
- Pre-built images for different OS and CPU architecture, along with installers. See INSTALLING.md for details.
- Visual representation of the GPIO pins in two layouts, a “Board Pin Layout” that mimics the
physical layout of the Pi’s GPIO connector/header, or a “BCM Pin Layout” with only the programmable
GPIO pins, ordered by BCM pin number. Physical pin layout adapts to reflect the device that
piggui
is connected to as Pi and Pi Pico pin outs are different. - Each pin has its board pin number, name and function.
- Drop down selector to config each pin (Currently as an Input with or without pull-up/pull-down, or as an Output)
- Inputs have a visualization like an LED to show its current level (Black is unknown, Red is off, Green is on), plus a waveform view that shows you the recent history of the level detected on the input.
- Outputs have a toggle switch that can be used to change the stable value of the output, plus a “clicker” for quick inversions of the stable level, plus a waveform view showing the recent history of the level set on the Output.
- GPIO configurations can be loaded at startup with a command line filename option, or loaded via file-picker from the UI or saved to file via file picker, or the device will communicate it’s current configuration to the GUI, allowing you to continue with the configuration currently being used by the GPIO hardware.
- GUI discovery of devices using mDNS for networked
pigglet
s andporky
s, or USB for direct connectedporky
s. - The GUI (
piggui
) can connect to a Pi (runningpigglet
) over the network, or to a Pi Pico/Pi Pico W (over the network or USB direct connect) to control and view the GPIO hardware from a distance. - The GUI can run on Mac, Linux, Windows or Raspberry Pis. Events are timestamped at source (as close to the hardware as possible) so network delays should not affect the waveforms displayed. Please provide us feedback and ideas related to networking in Discussions or GH issues.
- The data required to connect to a remote node via iroh-net is called the
nodeid
.pigglet
prints this out for you if it is started in the foreground. Whenpigglet
has been started as a system service, start another instance in the foreground and this will detect the background instance and display itsnodeid
for you then exit. - Take the
nodeid
and either supply it as a command line option topiggui
(--nodeid $nodeid
, prefixed with--
if usingcargo run
) or enter it into the GUI. To connect to a remote instance from the GUI, click on the “hardware menu” in the left of the info bar at the bottom of the screen and select the “Connect to remote Pi…” menu item. Then enter thenodeid
into the field provided and hit “Connect”
Subprojects and their README files
-
piggui
is a GUI for configuring pins, observing input levels and controlling output levels. README -
pigglet
is a “headless” command line utility that interacts with the GPIO hardware, and can either apply a config supplied from file and stop, or can listen for config changes from a remotepiggui
and report input level changes to the GUI. README -
porky
is an embedded application developer for the Raspberry Pi Pico and Pi Pico W for remote interaction with the Pico’s GPIO hardware. It can be connected to over TCP or USB. README
Supported Hardware and Operating Systems
pigg
has a number of binaries as part of the project (see descriptions above) and they are tested in CI, or
manually or are known to work as follows:
Installing
See INSTALLING.md
Help
See HELP.md for help with known issues. We hope to grow this and maybe link with the GUI and reported errors.
Building from Source
See BUILDING.md
Running Piggui and Pigglet
For details on running pigglet
and piggui
in the foreground or as a system service, on the same machine or with a
remote GUI to Pi hardware, see RUNNING.md
Roadmap
We have identified a number of areas to work on in future releases, most of which have been captured as GitHub issues, but we would really appreciate your input on what could be most useful or just the coolest.
