Top 10 Programming Languages in 2016 for Embedded Software Development

July 27th, 2016 4 comments

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 applications. The methodology used is interesting, as the company did…

Dragino LoRa/GPS HAT Board for Raspberry Pi Sells for $32

July 27th, 2016 8 comments

There are several ways to play with LoRaWAN protocol on the Raspberry Pi including RisingHF Discovery kit or Cooking Hacks LoRa Shield for Raspberry Pi, but the latter requires you to spend close to $100 just for the shield, the complete Lora discovery kit costs close to $400. Dragino Tech LoRa/GPS HAT board should be a more cost effective way to get started with LoRa on Raspberry Pi, as it sells for $32 + shipping on Tindie. Dragino LoRa/GPS HAT specifications: Connectivity LoRa Semtech SX1276/SX1278 transceiver @ 433/868, or 915 MHz (Country dependent, pre-configured in the factory) 168 dB maximum link budget. +20 dBm – 100 mW constant RF output vs. +14 dBm high efficiency PA.
