【導(dǎo)讀】隨著微電子技術(shù)迅速發(fā)展，單片機性能也得到迅速提高。路取代了以往的測量電路的數(shù)字邏輯控制電路，并將其發(fā)展。大的范圍，并得到廣泛使用。多重要場合受到限制。電路運行時好時壞，這是在某些場合是不允許的。僅僅是狗的連接環(huán)節(jié)也會時常出現(xiàn)無法識別的錯誤。后續(xù)脈沖外界條件觸發(fā)單片機工作。使用定時器，專用時鐘芯片或其它脈沖發(fā)生器在某一部分定期產(chǎn)生復(fù)位信號。發(fā)CPU執(zhí)行下次指令，這就是復(fù)位，這樣才能使抗干擾能力大大加強。可以想象熱水車輪轉(zhuǎn)動時保持溫度，CPU空閑，它可。所以，只要把復(fù)位的脈沖水車輪和CPU連接其來，水車輪每轉(zhuǎn)。一圈CPU復(fù)位一次，供暖才能正常進行，這就是復(fù)位法的外部條件。該復(fù)位無規(guī)律間隔出現(xiàn)，但它被證實了。50HZ電力使用后己經(jīng)省略定時器，在同一時間內(nèi)聚結(jié)相應(yīng)的信號相位，其中包。以通過常規(guī)單片機來制定上限下限。引玉，幫助大家，也希望每為同時共同探討，提高我們設(shè)計水平。
【正文】 old the conduct procedure. That is to say, are restored to the throne and suitable for the time that the procedure carries out during the low level Td of the signal, this time should be greater than the execution cycle of the procedure each time. It is restore to the throne cycle and restore to the throne high level of signal take empty than very much important to choose rationally. As to simple to show instrument, restore to the throne cycle determine data break cycle, low electricity is it measure, hence over all time shown to greater than to want at ordinary times。 otherwise, it can39。t present forever the mistake of the intact executive program. Monolithic integrated circuit in Ts and Tr period all can effectively the antigambling, but is best the unnecessary time arrangement in Tr. When the program time is long, as far as possible the request reduces Tr,it may join the differentiating circuit, like chart 1 center C30, R26, D9. Have the electricity to measure and restore to the throne manually Some systems in its initialization and runtime need first electrical impulses. Restored to the throne and already bee the beginning condition of normal running each time while adopting the way of restoring to the throne to run, it is unable to distinguish and have the electricity for the first time. In some pin connects the electric capacity of one Leif to the ground, measure this pin after being restored to the throne, if low level to have electricity for the first time. Give system set up one restore to the throne button, that is to say a mon one manual to restore to the throne, this button is not joined and being restored to the throne in the end, is connected in parallel in the electric capacity both ends to the ground of abovementioned pins. Result: Conclusion Antiinterference is an important problem in an electronic design, especially Important in the onechip puter. This is because the onechip puter has procedures to run particularity that flies, the consequence that it is interfered may be the system halted, may send out various kinds of mistakes or illegal movements before the system halted too, make the whole system produce the mortality mistake. So, only guarantee it is not enough yet for onechip puter not to crash, study how to reduce the risk interfered, it can befaulttoierant how is it after and make mistakes. This text is it act as some exploration from two these to try hard, hope these elementary opinions can play some function of casting a brick to attract jade, helpful to everybody。 Hope to every colleague explore together, improve our design level together．
