Windows

exit status 3221225781

When tinygo flash returns an error like this:

error: failed to flash C:\Users\Enrico\AppData\Local\Temp\tinygo393394635\main.hex: exit status 3221225781

This is most likely due to a missing .dll file. Install this to get the dll you need: https://sourceforge.net/projects/libusb-win32/

MacOS

If you have problems to find out, under which name the Arduino registers on your computer, try the following command:

ls /dev | grep usb

You are going to see an output like:

/dev/tty.usbmodem132408

This is the device you can put in the --p flag when using tinygo flash command

MQTT Broker

If you start the broker for the first time run the following command.

docker run -it --name mosquitto
--net=host
--restart=always
-p 1883:1883
-p 9001:9001
-v ~/go/src/github.com/PacktPublishing/Programming-Microcontrollers-and-WebAssembly-with-TinyGo/Chapter07/mosquitto/config/mosquitto.conf:/mosquitto/config/mosquitto.conf:ro
eclipse-mosquitto

For later starts just use:

docker start mosquitto
