Until now, we have programmed the EV3 bricks with the standard Lego programming software. Using messages to send commands from the PC and to retrieve status information from the EV3’s (this was not trivial, see this article https://siouxnetontrack.wordpress.com/2014/08/27/sending-data-over-wifi-between-our-pc-application-and-the-ev3-part-4/).
Programming the EV3’s with the standard programming language has as anything pros and cons. A major drawback, is that you can not do complex math. So we decided to convert all EV3 programs to EV3DEV and the C++ language.
I started this weekend with learning the EV3DEV environment and wrote my first, small test programming (pressing a touch sensor = motor rotates). Reading the manuals, learned me that you can do much more with the EV3 than with the standard programming environment.
For example, you can address the two LED’s on the brick separately. And it can also display four different grayscales on the display:
And this is all standard available!
