- [Using Sockets](#using-sockets)
## "net" Package
TinyGo's "net" package is ported from Go. The port offers a subset of Go's
"net" package. The subset maintains Go 1 compatiblity guarantee. A Go
application that uses "net" will most-likey just work on TinyGo if the usage is
within the subset offered. (There may be external constraints such as limited
SRAM on some targets that may limit full "net" functionality).
Continue below for details on using "net" and "net/http" packages.
See src/net/READMD.md in the TinyGo repo for more details on maintaining
TinyGo's "net" package.
## Using "net" Package
Ideally, TinyGo's "net" package would be Go's "net" package and applications
using "net" would just work, as-is. TinyGo's net package is a partial port of
Go's net package, so some things may not work because they have not been
ported.
There are a few features excluded during the porting process, in particular:
- No IPv6 support
- No DualStack support
Run ```go doc -all ./src/net``` in TinyGo repo to see full listing of what has
been ported. Here is a list of things known to work. You can find examples
of these at [examples/net](examples/net/).
### What is Known to Work
(These are all IPv4 only).
- TCP client and server
- UDP client
- TLS client
- HTTP client and server
- HTTPS client
- NTP client (UDP)
- MQTT client (paho & natiu)
- WebSocket client and server
Multiple sockets can be opened in a single app. For example, the app could run
as an http server listen on port :80 and also use NTP to get the current time
or send something over MQTT. There is a practical limit to the number of
active sockets per app, around 8 or 10, so don't go crazy.
Applications using Go's net package will need a few setup steps to work with
TinyGo's net package. The steps are required before using "net".
### Step 1: Probe to Load Network Driver
Call Probe() to load the correct network driver for your target. Probe()
allows the app to work on multiple targets.
```go
package main
import (
"tinygo.org/x/drivers/netlink/probe"
)
func main() {
// load network driver for target
link, dev := probe.Probe()
...
}
```
Probe() will load the driver with default configuration for the target. For
custom configuration, the app can open code Probe() for the target
requirements.
Probe() returns a [Netlinker](netlink/README.md) and a
[Netdever](netdev/README.md), interfaces implemented by the network driver.
Next, we'll use the Netlinker interface to connect the target to an IP network.
### Step 2: Connect to an IP Network
Before the net package is fully functional, we need to connect the target to an
IP network.
```go
package main
import (
"tinygo.org/x/drivers/netlink"
"tinygo.org/x/drivers/netlink/probe"
)
func main() {
// load network driver for target
link, _ := probe.Probe()
// Connect target to IP network
link.NetConnect(&netlink.ConnectParams{
Ssid: "my SSID",
Passphrase: "my passphrase",
})
// OK to use "net" from here on
...
}
```
Optionally, get notified of IP network connects and disconnects:
```go
link.Notify(func(e netlink.Event) {
switch e {
case netlink.EventNetUp: println("Network UP")
case netlink.EventNetDown: println("Network DOWN")
})
```
Here is an example of an http server listening on port :8080:
```go
package main
import (
"fmt"
"net/http"
"tinygo.org/x/drivers/netlink"
"tinygo.org/x/drivers/netlink/probe"
)
func HelloServer(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:])
}
func main() {
// load network driver for target
link, _ := probe.Probe()
// Connect target to IP network
link.NetConnect(&netlink.ConnectParams{
Ssid: "my SSID",
Passphrase: "my passphrase",
})
// Serve it up
http.HandleFunc("/", HelloServer)
http.ListenAndServe(":8080", nil)
}
```
## Using "net/http" Package
TinyGo's net/http package is a partial port of Go's net/http package, providing
a subset of the full net/http package. There are a few features excluded
during the porting process, in particular:
- No HTTP/2 support
- No TLS support for HTTP servers (no https servers)
- HTTP client request can't be reused
HTTP client methods (http.Get, http.Head, http.Post, and http.PostForm) are
functional. Dial clients support both HTTP and HTTPS URLs.
HTTP server methods and objects are mostly ported, but for HTTP only; HTTPS
servers are not supported.
HTTP request and response handling code is mostly ported, so most the intricacy
of parsing and writing headers is handled as in the full net/http package.
Run ```go doc -all ./src/net/http``` in TinyGo repo to see full listing.
## Using "crypto/tls" Package
TinyGo's TLS support (crypto/tls) relies on hardware offload of the TLS
protocol. This is different from Go's crypto/tls package which handles the TLS
protocol in software.
TinyGo's TLS support is only available for client applications. You can
http.Get() to an https:// address, but you cannot http.ListenAndServeTLS() an
https server.
The offloading hardware has pre-defined TLS certificates built-in.
## Using Sockets
The Netdever interface is a BSD socket-like interface so an application can make direct
socket calls, bypassing the "net" package for the lowest overhead.
Here is a simple TCP client application using direct sockets:
```go
package main
import (
"net" // only need to parse IP address
"tinygo.org/x/drivers/netdev"
"tinygo.org/x/drivers/netlink"
"tinygo.org/x/drivers/netlink/probe"
)
func main() {
// load network driver for target
link, dev := probe.Probe()
// Connect target to IP network
link.NetConnect(&netlink.ConnectParams{
Ssid: "my SSID",
Passphrase: "my passphrase",
})
// omit error handling
sock, _ := dev.Socket(netdev.AF_INET, netdev.SOCK_STREAM, netdev.IPPROTO_TCP)
dev.Connect(sock, "", net.ParseIP("10.0.0.100"), 8080)
dev.Send(sock, []bytes("hello"), 0, 0)
dev.Close(sock)
link.NetDisconnect()
}
```

## Examples Using GPIO or SPI
## Supported devices
If compiling these examples directly you are likely to need to make minor changes to the defined variables to map the pins for the board you are using. For example, this block in main.go:
```golang
var (
spi = machine.SPI0
csPin = machine.D5
)
```
It might not be obvious, but you need to change these to match how you wired your specific board. Constants are [defined for each supported microcontroller](https://tinygo.org/docs/reference/microcontrollers/).
For example, to change the definitions for use on a Raspberry Pi Pico using typical wiring, you might need to do this:
```golang
var (
spi = machine.SPI0
csPin = machine.GP17
)
```

// Package bma42x provides a driver for the BMA421 and BMA425 accelerometer
// chips.
//
// Here is a reasonably good datasheet:
// https://datasheet.lcsc.com/lcsc/1912111437_Bosch-Sensortec-BMA425_C437656.pdf
//
// This driver was originally written for the PineTime, using the datasheet as a
// guide. There is an open source C driver provided by Bosch, but unfortunately
// it needs some small modifications to work with other chips (most importantly,
// the "config file").
// The InfiniTime and Wasp-OS drivers for this accelerometer have also been used
// to figure out some driver details (especially step counting).

// This is the BMA421 firmware from the Wasp-OS project.
// It is identical to the so-called BMA423 firmware in InfiniTime, which I
// suspect to be actually a BMA421 firmware. I don't know where this firmware
// comes from or what the licensing status is.
// It has the FEATURES_IN command prepended, so that it can be written directly
