A Chimera of Standards, or the Challenges of Adapting Prototyping Standards

By: Greg Steiert

Abstract: There are always connections for interfacing programmable devices such as FPGAs and microcontrollers so that software development can begin along with, or before, the hardware. This article explains the very loose pseudo standards for the “expansion interfaces” that have emerged, some more consistent than others, and will discuss the Pmod standard for FPGAs and the Arduino pseudo standard for microcontrollers. It explains how to use the MAX14661 mux to design a simple interface from one standard to another.
