Programmable membrane switch input/output system

摘要: A programmable membrane switch input/output system is described. The includes a having matrix layout embedded in plastic film with plurality of switches located at specific locations on the film. Output lines from are electrically connectable to conversion unit which converts output signals first code dependent and position second independent layout. can convert into serial be transmitted serially processing device remotely switch. By transferring signal device, cable have fewer less space taken for connection. comprises microprocessor memory stores table code. also filter end key rollover by transmitting only one predetermined time period. drives LEDs seven segment displays response received information. method inputting information utilizing
