Overview
Periph is a standalone hardware library with limited external dependencies.
Features
- No external dependencies.
- No C dependency, doesn’t use
cgo. - Explicit initialization: know whathardware is detected and what isnot.
- Interfaces:GPIO (with edge detection),I²C,SPI,1-wire.
- Continuously tested viagohci.
- SemVer compatibility guarantee.

Tools
periph includes manyready-to-use tools:
go get periph.io/x/cmd/...# List the host drivers registered and/or initialized:periph-info# List the board headers:headers-list# List the state of each GPIO:gpio-list# Set P1_7/GPIO4 on a Raspberry Pi to high:gpio-write P1_71Library
periph tries hard to get out of the way whenused as alibrary.
Here’s the minimal “toggle a LED” example:
packagemainimport("time""periph.io/x/conn/v3/gpio""periph.io/x/conn/v3/gpio/gpioreg""periph.io/x/host/v3")funcmain(){host.Init()p:=gpioreg.ByName("11")t:=time.NewTicker(500*time.Millisecond)forl:=gpio.Low;;l=!l{p.Out(l)<-t.C}}Learn moreabout GPIOs.
