Audio Interfaces for embedded linux microcomputer in the Laboratory
On IEMKits, embedded microcomputer with Audio I2S bus, multichannel audio modules can added. A series of different interfaces, already available or on development, are waiting to be attached and evaluated. Within these laboratory exercises, these hacks should be tested: From attaching hardware, installing drivers to measurements with software tools on the boards.
Terminology
iemKits - are a collection of affordable open source hardware modules or boards, as a base for prototyping embedded musical instruments, sound installations and others. Using audio interfaces, controller and sensors let us create experimental open source hardware for research, educational purposes and individual usage.
iemKit Base - are embedded modules from Olimex A10,A20, A33 and A64 to beaglebones and others.
