Lego Mindstorms EV3 low level programming (EV3DEV)

[Hanso]

Did you know that any standard EV3 brick is capable of controlling the LEDS separately? And that the display is capable of displaying 4 shades of gray?

No, this extra functionality is not available via the standard programming environment that Lego provides. But if you use low level programming (I used EV3DEV in combination with C++), you have. See the example below.

You can read my article at our blog here: https://siouxnetontrack.wordpress.com/2020/04/25/lego-mindstorms-ev3-with-an-image-with-4-different-shades-of-gray/

Or have a look at the Youtube videos.

 

Enjoy.

A new article has been uploaded to our Wordpress blog. We have implemented the daisy chain functionality in our EV3DEV/C++ environment. The good news: it unlocks additional functionality, like more than 4 bricks can be chained, daisy chain using WiFi and accessing the leds and the display on the slave bricks ...

The full article can be found here: https://siouxnetontrack.wordpress.com/2020/07/14/our-ev3dev-c-daisy-chain-unlocks-additional-functionality/

And (of course) an example on Youtube:

(the USB cable at the master brick is connected to the PC for starting the EV3DEV program with the IP address of the slave)
