Ethernet

Connecting Microcontrollers To Wired LANs (Local Area Networks)

Wired network connection may be necessary if you want to permanently connect a microcontroller to a LAN in the most robust way. While many microcontrollers these days come with wireless connectivity built-in, rarely do you find microcontroller boards with Ethernet adapters.

Wired connections may even be required for certain use cases: if you’d like to wake up computers in your LAN using WOL (Wake-On-LAN), the magic packets that do the wakeup need to be sent to the wired network. You cannot wake up other computers via WOL with a WiFi device.

Ethernet Adapter Boards

Adding Ethernet connectivity is cheap and simple. There are ready-to-use Ethernet breakout boards that come with the RJ45 jack to plug in typical CAT cables.

At the heart of an Ethernet breakout board is the Ethernet controller:

  • ENC28J60: Ethernet breakout board based on the ENC28J60 controller using a SPI interface and running on 3.3V

Slow Website?

This website is typically very fast, and pages should appear instantly. If this site is very slow for you, then your routing may be messed up, and this issue does not only affect done.land, but potentially a few other websites and downloads as well. Here are simple steps to speed up your Internet experience and fix issues with slow websites and downloads..

Comments

Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.

Discussions

For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
