The 1 at the end of geometry means that there is 1 bit per pixel. So, each byte in the buffer represents 8 pixels. The leftmost pixel is in the least significant bit. Visual : MONO01 tells us that the value 0 is white and the value 1 is black.. LineLength : 24 means that each horizontal line is 24 bytes. If you do the math, 178 pixels / 8 bits per byte * 1 bit per pixel = 22.25 bytes. CONNECTING TO THE INTERNET VIA USB Now, we need to assign an IP address to our EV3.

Most, if not all, of the customization of the ev3dev kernel is the addition and patching of hardware drivers for the EV3 specific hardware. GETTING STARTED WITH LEGO MINDSTORMS EV3 Download and install Etcher. Download the latest ev3dev image for LEGO MINDSTORMS EV3 from the ev3dev downloads page. Note. Follow the link on that page for ev3dev-stretch snapshot images. Run Etcher and flash the image to the microSD card. Click here if you need detailed instructions on using Etcher. Put the microSD card in the EV3 and turnit on.

EV3DEV IS YOUR EV3 _RE-IMAGINED_ ev3dev is a Debian Linux -based operating system that runs on several LEGO® MINDSTORMS compatible platforms including the LEGO® MINDSTORMS EV3 and Raspberry Pi -powered BrickPi.
Just like you can take apart your LEGO® models and build something completely different, we have reverse-engineered the EV3 and created a new software platform for programming your robots. EV3 PROGRAMMING UNLOCKED ev3dev gives you the power to program how _you_ want to. We have created a low-level driver framework for controlling sensors, motors and pretty much everything else. It’s as easy as reading from andwriting to a file.
ev3dev supports many popular scripting languages out-of-the-box, so you can get started right away with your favorite language andlibraries.
__ BACKED BY THE FULL POWER OF LINUX Since ev3dev is built on Debian Linux, there are over 51,000 free software packages available for you to install. And with the Linux kernel at its core, many USB and Bluetooth devices, like Wi-Fi dongles, keyboards, keypads, joysticks and cameras worktoo.
IT’S NOT FIRMWARE
It’s more like dual-boot. ev3dev runs from a microSD card and doesn’t ever touch the firmware installed on the EV3. To switch back, you just shut down and remove the microSD card - no flashingrequired.
