#190512 - the code you mentioned is from a very old thread from 8052.c Responding to: ???'s previous message |
the code you mentioned is from a very old thread from 8052.com
http://www.8052.com/forum/read/57958 dated from 2003 you have to completely enroll to the thread from the first to the last answer there. That thead started with a <<puzzle>> from Micahel Karas asking for Sometimes an 8051/8051 microcontroller may need to monitor and debounce filter a multiple of inputs ... http://www.8052.com/forum/read/57921 this is a clever way to debounce multiple inputs, but I prefer the more robust method of majority vote, where every input is sampled for state and transition (timer based) and at a predefined number of samples (or a sliding window) the final status (state/transition) is determined by simple and strict rules according to the need of the application. |
