Input and display of setting values in electronic equipment - has stored digital values called by rotary selector for control of cooker temperature

摘要

A rotary selector input for use on domestic cookers is designed to provide a digital setting value that is displayed. The rotary input is turned (10) and produces pulses (12) that are reduced by a divider (13) to trigger a bi-directional counter (7). A specific count value, which corresponds to a specific angle of input selector rotation, provides access to a memory (19) that generates an output indicating a temperature range, e.g. 0,240 or 280 degrees. The values are transmitted to a buffer memory (20) and are decoded (15) for display (14).
