【正文】 第一次測量是低電平則一些引腳是連接電容后接地。給系統(tǒng)設(shè)置一個復(fù)位按鈕，那就是說一個共同的復(fù)位，此按鈕是不是加入復(fù)位，要看最后并聯(lián)在電容兩端的引腳接地情況。 結(jié)果： 反干擾是電子設(shè)計中的重要問題，尤其是在單片機中。 這是因為單片機程序運行的特殊性所導(dǎo)致的。干涉可能導(dǎo)致該系統(tǒng)停止運行，也可能引發(fā)個種錯誤或非法轉(zhuǎn)移，使整個系統(tǒng)產(chǎn)生死機的錯誤。就這么一說對單片機整個發(fā)展來說是不夠的，我們要研究如何降低干擾風(fēng)險，使它完善以減少不必要的錯誤。這文章只是充當(dāng)一些探索，從這兩個方面努力，希望這些小小的建議，可以發(fā)揮一些效果 , 鑄造拋磚引玉，幫助大家，也希望每為同時共同探討，提高我們設(shè)計水平。 附件 2：外文原文 SingleChip Microputer dormancy puting reset and the antiinterference ability is perfect Abstract: Introduce a kind of dormancy of using restore to the throne in the operation way and improve the antiinterference ability method of the onechip puter,Analyse its scope of application, provide and use the circuit concretely。 Combine the instance, analyze the characteristic of the hardware and software design under these kind of operation way. Keyword: SingleChip Microputer Restore to the throne, dormancy, antiinterference Preface: With the development at full speed of the micro electric technique, the performance of the onechip puter improves rapidly, demonstrate the outstanding advantage in the operation, logic control, intelligent respect, replaced and enlarged the measuring that the circuit made up, control circuit by digital logical circuit, operation originally to a great extent, use very extensively. But because it have system halted, procedure run critical defect of flying etc, make it limit in a lot of important application of occasion. A lot of technology in antiinterference , for example set up the software trap, add the hardware to guard the gate in dog39。s circuit etc, can make this problem have better settlement, but still the existing problem: (1)Guard the gate dog at the movement, mean and appear mistake already and run some time, this is not allowed in some occasions。 (2)Procedure appear circulation mistake very much sometimes, but just guard the gate dog control link include and enter, adopt and guard the gate as to such a mistake dog unable to discern。 (3) In measure and control cycle among the long system, onechip puter spend wait for the peripheral hardware a large amount of time, will be interfered too when carry out and wait for the order. To these situations, we have tried the method restored to the throne voluntarily in practice, alternate pulse of adopting etc or restore to the throne waking according to external terms to the onechip puter up. After being restored to the throne each time, the onechip puter carries out the corresponding procedure, enters dormancy in time after finishing carrying out the task, wait to be restored to the throne neatly. Have solved abovementioned problems well with this method, and
