Comprehensive Raspberry Pi Benchmark. Part
A Comprehensive Raspberry Pi 3 Benchmark. Part 2

I thought it would be good to include this for retro' computing sake, especially considering that the Raspberry Pi is intended to be going back to the roots of learning how to code and programme with a capable hands-on computer platform. nBench has been around for so long that you can compare these benchmark results against older processors such as the 386 and even 486 based processors right up to the Intel Core i7...

No way back smart microcontroller says
No way back for the 'smart' microcontroller, says Microchip

Microcontrollers are becoming system-on-chip devices and there is no way back for the ubiquitous controller device, says supplier Microchip. Even low cost 8-bit microcontrollers now integrate a large number of peripheral circuits ranging from timers to encryption circuits, which operate independently of the processor core...

Alorium Technology FPGA dev board Arduino
Alorium Technology's FPGA dev board, Arduino compatible, in distribution

Mouser Electronics has announced a global distribution agreement with Alorium Technology, producers of the XLR8 development board which integrates an ATmega328-compatible microcontroller core and custom accelerator blocks on a field-programmable gate array...

Comprehensive Raspberry Pi Benchmark. Part
A Comprehensive Raspberry Pi 3 Benchmark. Part 1

Our good friend biglesp put the Raspberry Pi 2 to the test the last time around, though I feel that he missed a good number of possible benchmarks to run on the hardware. With that in mind, I'm going to test the main boards of the Raspberry Pi that I can get my hands on and not only run the main benchmarks Les ran, but also a good few more thanks to Roy Longbottom's benchmark collection. I also have some approximate information on idle power usage, which everyone appears to be interested in...

STMicroelectronics Arduino Launch Cooperation Expand Maker-Community
STMicroelectronics and Arduino Launch Cooperation to Expand Maker-Community Access to STM32 MCUs and Sensors

Moving to enable makers to make even more than before, STMicroelectronics , a global semiconductor leader serving customers across the spectrum of electronics applications, and Arduino , the world’s leading open-source ecosystem for Education, Maker, and IoT markets, today announced an agreement that brings the industry-leading STM32 family of microcontrollers, along with ST’s full portfolio of sensing, power, and connectivity technology, even closer to the Arduino maker community...

Create 16x16 LED Displays Flexible Reference
Create 16x16 LED Displays with Flexible Reference Design

Hobbyists and makers now have more flexibility and options when developing LED signs, using the MAXREFDES99# 16×16 display reference design from Maxim Integrated Products. LEDs continue to dramatically transform signage and lighting. However, often LED displays today are 8×8 and cannot communicate many international alpha-numeric characters. MAXREFDES99# integrates four MAX7219 LED drivers to provide designers a 16×16 display with 256 LEDs, allowing them to create signs in multiple languages...

Expansion Shield RaspberryPi compatible Arduino. Part
Expansion Shield for RaspberryPi compatible with Arduino. Part 2 - Use the Shield on RaspberryPi

To proceed in subsequent operations, use RaspberryPi in terminal mode, the two SSH and SCP windows open and root login. Connect the RPY connector of the shield to the GPIO RaspberryPi connector and give voltage. Now we shall activate the I2C and SPI management modules (drivers in the Windows world) or just one of the two, depending on your needs...

Expansion Shield RaspberryPi compatible Arduino. Part
Expansion Shield for RaspberryPi compatible with Arduino. Part 1 - Schematic

Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will allow you to add a DAC, a number of additional digital I/Os and the ability to connect also with non GPIO enabled boards...

AVR takes under micro process quadrature
AVR takes under 1µs to process quadrature encoder

Reading quadrature encoder signals at high speeds often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function using only an ATtiny2313A AVR microcontroller...

Arduino Primo base board features native
Arduino Primo base board features native Bluetooth low energy wireless connectivity and NFC Touch-to-Pair using Nordic Semiconductor nRF52832 SoCs

Nordic Semiconductor announces that Arduino – the world’s most successful open-source ecosystem for education, Maker, and Internet of Things markets – has specified the Nordic Semiconductor nRF52832 Bluetooth low energy System-on-Chip at the heart of its latest product: a low cost IoT-targeted programmable single board computer (or ‘base board’) called the ‘Arduino Primo’...
