Add basis for TCP/IP stack. The stack implements Netdever interface for the top-end, and calls into a Netlinker interface on the bottom-end. Each TCP/IP stack instance represents a L3/L4 endpoint with an IP address. The Netlinker is bound when creating the stack. E.g.: spi, cs, wlreg, irq := cyw43439.PicoWSpi(0) cyw43 := cyw43439.NewDevice(spi, cs, wlreg, irq, irq) stack := tcpip.NewStack(cyw43) netdev.UseNetdev(stack) Here, the cyw43439 driver is the Netlinker for the stack. The new stack is a Netdever, so we tell the "net" package to use the stack as the netdev. The stack manages L3/L4 socket connections, ultimately calling into the Netlinker to send/recv L2 Ethernet pkts.
TinyGo Drivers
This package provides a collection of 101 different hardware drivers for devices such as sensors and displays that can be used together with TinyGo.

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)
}
}
