Bit sequence evaluating method for providing binary switching status to e.g. vehicle light, involves setting data signal to one and zero, when counter has values which are in respective halves of counter range

摘要

The method involves setting a sample counter (D) to a predetermined value, when a de-bouncing counter (C) reaches a threshold value. A data signal is generated when the counter (D) reaches a predetermined value. The data signal is set to one, when the counter (C) has a value which is in the half of the counter range. The data signal is set to zero when the counter (C) has a value, which is in the other half of the counter range.
