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

Using a PIC MCU to read out the MAX6675 temperature sensor (LCD,USB)

This project is about using the Microchip PIC18F13K50 MCU as a USB-serial controller, read out the MAX6675 temperature sensor and write some output on a LCD display. It came up to gain experience with the PIC18 MCU and see how

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
