Aspencore 2017 Embedded Markets Study – Programming Languages, Operating Systems, MCU Vendors, and More

Aspencore media group asked readers of their EE Times and Embedded.com websites to fill out an online survey about their embedded system projects. They got 1,234 respondents mostly from North America (56.3%), followed by Europe (25.2%), and Asia (10.6%). This resulted in a 102-page market study which you can download here. I’ve extracted a few slides to have a look at some of the trends. C language is still the most used language in embedded systems, but other languages like C++, Python and even assembly language are gaining traction. Operating system is more spread with Linux being the most used via Embedded Linux distributions, Debian, and Ubuntu. FreeRTOS comes in second place, while Android registers fourth with 13%. Git has finally supplanted Subversion in 2017, with all other version control software losing ground. Switching to some hardware slides, 44% used a development board to start their embedded design with ST […]

Think Silicon Ultra Low Power NEMA GPUs are Designed for Wearables and IoT Applications

When you have to purchase a wearable device, let’s say a smartwatch or fitness tracker, you have to make trade offs between user interface and battery life. For example, a fitness tracker such as Xiaomi Mi Band 2 will last about 2 weeks per charge with a limited display, while Android smartwatches with a much better interface need to be recharged every 1 or 2 days. Think Silicon aims to improve battery life of the devices with nicer user interfaces thanks to their ultra-low power NEMA 2D, 3D, and GP GPU that can be integrated into SoCs with ARM Cortex-M and Cortex-A cores. The company has three family of GPUs: NEMA|p pico 2D GPU with one core 4bpp framebuffer, 6bpp texture with/out alpha Fill Rate – 1pixel/cycle Silicon Area – 0.07 mm2 with 28nm process Power Consumption – leakage power GPU consumption of 0.06mW; with compression (TSFSc): 0.03 mW NEMA|t […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]

ELLO 2M is a DIY Computer with a Keyboard, a 7″ Touchscreen Display and a Prototyping Area (Crowdfunding)

ELLO_2M

The traditional way to play with electronics is to get a board (e.g. Arduino), a breadboard to wire components & sensors to the board, and a computer for programming.  ELLO 2M combines all that into a single piece of hardware with a 7″ touchscreen display, a Microchip PIC32 micro-controller board, a solderless prototyping area made of PGA sockets, and a keyboard. ELLO 2M hardware specifications: MCU – Microchip PIC32MX470 32-bit micro-controller @ 120 MHz with 128kB RAM (512kB RAM in the ELLO 2M “hacker” versions) Extra System Memory – Optional on-board serial non-volatile data RAM Storage – 3x micro-SD cards (one permanently built-in and two for removable storage); internal serial FRAM Display – 7″ LCD touch-screen panel with 800×480 pixel resolution Audio – Small speaker and buzzer Keyboard – Replaceable QWERTY keyboard Connectivity – 2.4GHz RF communication module with simple communication protocol Expansion – Expansion receptacle, electronic prototyping space with […]

Microchip Introduces MPLAB Xpress Cloud-based IDE and MPLAB Xpress Evaluation Board

Microchip has just launched MPLAB Xpress online IDE with some of the most used features of the company’s MPLAB X IDE, as well as a free – in limited quantities – MPLAB Xpress evaluation board based on a PIC16 micro-controller.

Visit MPLAB Xpress Code Examples page, load one of the example, possibly log-in if you want to save changes to the 10GB free online storage […]

Microchip Introduces $11 RN2483 & RN2903 LoRa Modules and $70 LoRa Evaluation Kits for IoT & M2M Applications

LoRa is one of those long range low power WAN standards used for the machine to machine (M2M) and Internet of things (IoT) applications. I already featured a Semtech Lora module here with a line-of-sight range of up to 20 to 30km, and the company has just partnered with STMicro to deploy LoRa solutions, but today, I’m going to have a look at Microchip Lora modules and development kits that I discovered in the company’s Micro Solutions Nov/Dec 2015 publication. The company has launched two modules for the European and North American markets with respectively RN2483 LoRa 433/868 MHz R&TTE Directive Assessed Radio Modem and RN2903 915 MHz North American modem. Apart from the different frequencies, both modules have similar features: On-board LoRaWAN Class A protocol stack Tx/Rx Power RN2483 – 40 mA (14dBm, 868MHz) Tx, and 14.2 mA Rx @ 3.6V RN2903 – 124 mA Tx max, and 13.5 mA […]

GroBotz Interactive Robot Project is Made of Easy to Assemble Smart Blocks (Crowdfunding)

GroBotz makes me think of Lego applied to robotics. The project consists of modules such as motors, sensors, buttons, switches, or cameras that snap together in order to create a robot on wheels, games, toys, a musical instrument, or whatever idea you may have, and the hardware is then programmed using a graphical user interface. A Raspberry Pi board is used for the brain of the robot, and Microchip PIC MCUs for the smart blocks. The software is programmed in C# using Xamarin, the user interface is based on Unity, OpenCV is used for image processing, and during development a plastic part where printed with Makerbot, and schematics and PCB layout designed with CadSoft EAGLE. The company has now come up with a number of modules as shown in the picture below. Your robot can then be controlled over Wi-Fi with GroBotz app which works on Windows, Mac OS, iOs, […]
