Cypress System on Chip Entry Kit

System on a Chip (SoC) devices are becoming ever cheaper and represent a great way to develop micro controller apps with the minimum of external components. A typical SoC device comprises a micro controller core along with a stack of logic and analogue blocks that can be configured in firmware to create a specialist device. […]

If you are thinking of getting into FPGAs (Field Programmable Gate Arrays) it’s worth paying a visit to Gadget Factory’s Papilio project. Not only do they have some great value boards available but the new Schematic Library really helps you get going with minimal programming. The Schematic library provides computing modules that can be arranged […]

CPLD Development Boards

I’ve been spending a lot of time recently playing with CPLDs (Complex Programmable Logic Devices). These are wonderful devices for the logic experimenter as you can build your own dedicated logic chips! I started by getting the excellent Guzunty Pi which is an excellent value board complete with software that allows you to load different […]
