We need to support compilation for SAMD21 based boards.

This doesn't show up in the console

print("ABC") // no output

This does

print("ABC\n")  // output: ABC

This works

println("ABC") // output: ABC

This "too"

print("ABC") 
print("DEF")  // output: ABCDEF

In order to update to Go 1.18 the docker container/runner needs to be updated to use Go modules.

We need to have support for a "button" part so we can make it interactive.

The error "upstream request timeout" is occurring frequently on the Playground website when trying to download code using the "Flash" button.

I do not have the same issue/slowness when compiling inside the web interface for the simulator.

Currently, Tthe compiler can only handle creating HEX files for download. We also need to be able to compile UF2 format files.

I am unable to compile any programs on the TinyGo Playground website:

This is the output in the right pane:

LinkError: WebAssembly.instantiate(): Import #8 module="env" function="syscall/js.valueNew" error: function import requires a callable

I think there are some updates that are still pending that are used for the serverless compilation?

The LED in the Arduino UNO example does not blink in the browser.
Tested at https://play.tinygo.org/

I am using Ubuntu 20.04 and a Firefox (latest version)

I think adding the code sharing feature would be great.
It will also have an impact on the spread of this project.

We need support for the Circuit Playground Bluefruit

This program works as expected on the actual hardware (red/blue LEDs) but on the simulator is red/green:

package main

import (
	"image/color"
	"machine"
	"time"

	"tinygo.org/x/drivers/ws2812"
)

var leds [10]color.RGBA
var led = machine.LED
var neo = machine.NEOPIXELS

func main() {
	led.Configure(machine.PinConfig{Mode: machine.PinOutput})
	neo.Configure(machine.PinConfig{Mode: machine.PinOutput})

	ws := ws2812.New(neo)
	rg := false

	for {
		rg = !rg
		for i := range leds {
			rg = !rg
			if rg {
				leds[i] = color.RGBA{R: 0xff, G: 0x00, B: 0x00}
			} else {
				leds[i] = color.RGBA{R: 0x00, G: 0x00, B: 0xff}
			}
		}

		ws.WriteColors(leds[:])
		led.Set(rg)
		time.Sleep(100 * time.Millisecond)
	}
}

I get this message and I can't run it locally.

LinkError: import object field 'syscall/js.finalizeRef' is not a Function

It would be great if I could share a code snippet with other people like https://play.golang.org/ (Share button).
