Keyboard and display multiplexing - the traditional approach
09.20.2016 · Circuits
Webster’s Dictionary defines “multiplex” as “many” or “multiple”. Coincidentally, in an electronics context the word can have several meanings. Whilst they all share the intention to economize on the number of connections used, there are subtle differences. It can mean combining messages on to a single communications channel for transmission and reception. In a similar vein, it can also mean configuring several continuous inputs (either digital or analog) so that only one is accessed at a time...
