## Example
|
||||
## New home
|
||||
|
||||
Blink a LED:
|
||||
|
||||
~~~go
|
||||
package main
|
||||
|
||||
import (
|
||||
"time"
|
||||

"periph.io/x/periph/host"

func main() {
|

host.Init()
|
||||
t := time.NewTicker(500 * time.Millisecond)
|

for l := gpio.Low; ; l = !l {
|
||||
rpi.P1_33.Out(l)

// Package conn defines core interfaces for protocols and connections.
|
||||
//
|
||||
// This package and its subpackages describe the base interfaces to connect the
|
||||
// software with the real world. It doesn't contain any implementation but
|
||||
// includes registries to enable the application to discover the available
|
||||
// hardware.
|
||||
// Is it now superseded by https://periph.io/x/conn/v3 (or later).
|
||||
//
|
||||
// Concepts
|
||||
//
|
||||
// periph uses 3 layered concepts for interfacing:
|
||||
//
|
||||
// Bus → Port → Conn
|
||||
//
|
||||
// Not every subpackage expose all 3 concepts. In fact, most packages don't.
|
||||
// For example, SPI doesn't expose Bus as the OSes generally only expose the
|
||||
// Port, that is, a Chip Select (CS) line must be selected right upfront to get
|
||||
// an handle. For I²C, there's no Port to configure, so selecting a "slave"
|
||||
// address is sufficient to jump directly from a Bus to a Conn.
|
||||
//
|
||||
// periph doesn't have yet a concept of star-like communication network, like
|
||||
// an IP network.
|
||||
//
|
||||
// Bus
|
||||
//
|
||||
// A Bus is a multi-point communication channel where one "master" and multiple
|
||||
// "slaves" communicate together. In the case of periph, the Bus handle is
|
||||
// assumed to be the "master". The "master" generally initiates communications
|
||||
// and selects the "slave" to talk to.
|
||||
//
|
||||
// As the "master" selects a "slave" over a bus, a virtual Port is
|
||||
// automatically created.
|
||||
//
|
||||
// Examples include SPI, I²C and 1-wire. In each case, selecting a
|
||||
// communication line (Chip Select (CS) line for SPI, address for I²C or
|
||||
// 1-wire) converts the Bus into a Port.
|
||||
//
|
||||
// Port
|
||||
//
|
||||
// A port is a point-to-point communication channel that is yet to be
|
||||
// initialized. It cannot be used for communication until it is connected and
|
||||
// transformed into a Conn. Configuring a Port converts it into a Conn. Not all
|
||||
// Port need configuration.
|
||||
//
|
||||
// Conn
|
||||
//
|
||||
// A Conn is a fully configured half or full duplex communication channel that
|
||||
// is point-to-point, only between two devices. It is ready to use like any
|
||||
// readable and/or writable pipe.
|
||||
//
|
||||
// Subpackages
|
||||
//
|
||||
// Most connection-type specific subpackages include subpackages:
|
||||
//
|
||||
// → XXXreg: registry as that is populated by the host drivers and that can be
|
||||
// leveraged by applications.
|
||||
//
|
||||
// → XXXtest: fake implementation that can be leveraged when writing device
|
||||
// driver unit test.
|
||||
// See https://periph.io/news/2020/a_new_start/ for more details.
