Scott Feldman 1fd8a768ae netlink: add L2 bridge/bond/vlan intermediate drivers
This adds three new L2 (intermediate) drivers for bridge/bond/vlan.
Theses drivers are incomplete but illustrate how to stack L2 drivers.
Here are some examples of how these driver would stack with the cy243439
driver:

  Bridge: bridge two cyw43 devices together, connecting the two LANs:

	cyw43_0 := cyw43439.NewDevice(...)
	cyw43_1 := cyw43439.NewDevice(...)

	bridge := NewBridge([]netlink.Netlinker{cyw43_0, cyw43_1})

	stack := tcpip.NewStack(bridge)
	netdev.UseNetdev(stack)

  Bond: bond two cyw43 devices together, creating one logical device.
  The first physical device is primary, the second is backup (fail-over)
  device:

	cyw43_0 := cyw43439.NewDevice(...)  // primary
	cyw43_1 := cyw43439.NewDevice(...)  // secondary (backup)

	bond := NewBond([]netlink.Netlinker{cyw43_0, cyw43_1})

	stack := tcpip.NewStack(bond)
	netdev.UseNetdev(stack)

   Vlan: add tagged VLAN ID=100 to cyw43:

	cyw43 := cyw43439.NewDevice(...)

	vlan100 := NewVlan(100, cyw43)

	stack := tcpip.NewStack(vlan100)
	netdev.UseNetdev(stack)

TinyGo Drivers

PkgGoDev Build

This package provides a collection of 101 different hardware drivers for devices such as sensors and displays that can be used together with TinyGo.

For the complete list, please see: https://tinygo.org/docs/reference/devices/

Installing

go get tinygo.org/x/drivers

How to use

Here is an example in TinyGo that uses the BMP180 digital barometer:

package main

import (
    "time"

    "machine"

    "tinygo.org/x/drivers/bmp180"
)

func main() {
    machine.I2C0.Configure(machine.I2CConfig{})
    sensor := bmp180.New(machine.I2C0)
    sensor.Configure()

    connected := sensor.Connected()
    if !connected {
        println("BMP180 not detected")
        return
    }
    println("BMP180 detected")

    for {
        temp, _ := sensor.ReadTemperature()
        println("Temperature:", float32(temp)/1000, "°C")

        pressure, _ := sensor.ReadPressure()
        println("Pressure", float32(pressure)/100000, "hPa")

        time.Sleep(2 * time.Second)
    }
}
