Ollie Milton / CD22M3494Matrix

Driver for a CD22M3494 cross point switcher

Library description

The CD22M3494 is a 16x8 crosspoint switch matrix, it can be used in any configuration i.e. 16 ins' 8 outs' or 16 outs' and 8 ins'. Control of the chip is pretty simple there are two parallel address buses a 4 byte address controls the X axis (16 IO pins) and a 3 byte address controls the Y axis (8 IO pins). A data bus says whether to open or close the switch and a 'strobe' bus actually performs the switch. This library provides a simple interface to control the CD22M3494 and provides a mechanism to associate source and destinations in pairs and switch the pairs via their names.
