利用單片機制作音樂播放器的課程設計報告. 作為單片機的重要硬件資源之一,利用定時器可以產(chǎn)生各種固定頻率的方波信號,也可以產(chǎn)生包括“Do“、“Re“、“Me“--等音階在內的各種頻率聲音。在此設計中我們采用12MHz的晶振,產(chǎn)生的頻率信號即音樂信號由P3.7口輸出,信號經(jīng)過放大后由喇叭發(fā)出聲音。

由于學cracking時匯編(Assembly)是不可避免要接觸的,我的第一個想法就是先學windows平臺下的匯編語言,由于現(xiàn)在的windows操作系統(tǒng)都是32位的(win9x系列是16/32混合型),那學匯編當然也要學32位的,但現(xiàn)在我們又遇到了同樣的問題,我們去哪里找相關的學習資料,說到這里,我必須感慨一下,縱觀一下現(xiàn)在的國內計算機基礎教育,很大程度上還很落后,就拿權威的國家計算機等級考試,所考科目剛剛取消DOS,升為windows 95,在操作系統(tǒng)霸主微軟公司歷經(jīng)DOS、Windows3.x,Windows9X,以及輕輕地跨過Windows Me,進入XP時代之后,我國計算機等級考試還留著DOS的老牛車,直到今年下半年全面停考,可見脫節(jié)是多么嚴重(這一句是摘抄);另外,在大學計算機專業(yè),現(xiàn)在用的匯編教材也是講的最古老的Intel8086系列16位匯編,不知道哪一天中國的教育才能真正走上與所謂國際接軌的道路。

All programs were tested using a breadboard containing a DS80C320, 32K Program memory, 32K Data memory, two 8-segment bar graph LEDs/drivers, and an 11.0592 MHz crystal. The four 8-segment bar graph LEDs/drivers were connected to ports 1, and 3 to display their pins states.

Swfdec still is development software, but has also followed a rigid no-crashes-allowed policy. I believe it s stable enough now to be installed as a default plugin for people that can live with occasional crashes of their browser. But don t blame me if it does crash.
