Description
The complimentary metal-oxide-semiconductor (CMOS) logic family contains an array of integrated circuits that perform all the tasks necessary for rudimentary computation. Designed for applications that require raw electronic processing power, the speed at which these chips operate can be slowed and their binary processes repurposed for creative applications.
In this workshop, participants will learn how to utilize the functions of several chips from the CMOS family including the basic Boolean gates (AND, NOR, XOR, etc.), Schmitt trigger oscillators, frequency dividers, shift registers, and multiplexers. We will cover techniques for connecting the inputs and outputs of these chips to generate patterns for controlling software. Protocols for communication covered will include UART (Arduino serial), MIDI, and OSC. Finally, we will connect all projects together to form a giant modular controller.
