Top 10 Programming Languages in 2016 for Embedded Software Development

IEEE Spectrum has published a list of the top programming languages in 2016 for Web, Mobile, Enterprise, and Embedded sectors with rankings created by weighting and combining 12 metrics from 10 sources. So I thought it would be fun to have a look at the top 10 of languages used for embedded software, and the results are: As expected, C and C++ are at the top, but I’m quite surprised that “Arduino” is now considered a programming language, as it is simply based on C/C++. When I worked as an embedded software engineer a few years ago, I personally used C, and Assembly, and to a lesser extend C++ and VHDL. I only recently started to play with Arduino code, and while I’ve heard of most other languages in the list, it’s the first time I’ve ever seen Ladder Logic, probably because it’s designed to program PLCs in industrial control […]

LabVIEW Now Supports Raspberry Pi 2 & 3, BeagleBone Black with LINX 3.0 Release

LabView is a system-design platform and development environment with a graphical programming syntax that “makes it simple to visualize, create, and code engineering systems”. It’s often used with National Instruments hardware such as myRIO, but LabView Makerclub has also developed LINX to bring support to Arduino and chipKIT, and with the latest LINX 3.0, support for BeagleBone Black, and Raspberry Pi boards has been added. You’ll need Labview 2014 (Windows only) or greater to work with LINX 3.0, as well as one of the supported development boards. Complete Labview 2014 + board kits are also sold with the BeagleBone Black Physical Computing Kit and Raspberry Pi 2 Physical Computing Kit both going for $89 on Digilent. LabView files are save in VI format, and the same file can be used on Arduino, BeagleBone Black, and Raspberry Pi board with minor modifications (e.g. GPIO pin number) as shown in the blink […]
