Playing with the Cyclone V SoC system – DE0-Nano-SoC Kit/Atlas-SoC

Recently I bought the DE0-Nano-SoC Kit/Atlas-SoC development board from Terasic which contains a Cyclone V SoC from Altera. The board is a good starting point to get involved in embedded system development with SoCs. The Cyclone V SoC is a

PICkit2 programming with MPlabX – PIC16F690 UART ADC

A while ago I discovered that I own a PICkit2, which I had bought a while ago when I started to study microprocessors. With MPLabX Microchip has a IDE which runs under Linux, so I gave the kit a second

Arduino Due clone based on the Atmel SAM3X8E, KiCAD design

This project came up to test PCB design with KiCAD. Some Atmel SAM3X8E microprocessors were available, the same as one finds on the Arduino Due, and I got tired on the limitations of the free version of Eagle. So I
