【正文】 課設是一個通過思考、發(fā)問、自己解惑并動手、提高的過程。使我受益匪淺，更加明確了自己專業(yè)的方向。一方面通過C51單片機等一些器件的設計讓我學習和掌握了單片機技術的基礎知識和技術要點，也使以前學的很多知識都得到了運用；另一方面在用Proteus軟件畫電路圖時，然后再轉換成一維的WORD中進行編輯，這個過程中讓我掌握了計算機輔助的設計技術。而且波形也產生的很漂亮和標準。 } } }}void time0() interrupt 1{ time=1。 break。 switch(flag) //當按鍵1的為輸出三角波，按鍵2時輸出正弦波 { case 0AC0832(0)。 display()。TR0=1。IT1=1。TMOD=0X02。} if(d4==0){ delay(5)。} if(d2==0){ //delay(5)。 p26=0。 unsigned char sin(unsigned char x){unsigned char code sin_tab[]={125,128,131,134,138,141,144,147,150,153,156,159, 162,165,168,171,174,177,180,182,185,188,191,193,196,198,201,203, 206,208,211,213,215,217,219,221,223,225,227,229,231,232,234,235, 237,238,239,241,242,243,244,245,246,246,247,248,248,249,249,250, 250,250,250,250,250,250,250,249,249,248,248,247,246,246,245,244, 243,242,241,239,238,237,235,234,232,231,229,227,225,223,221,219, 217,215,213,211,208,206,203,201,198,196,193,191,188,185,182,180, 177,174,171,168,165,162,159,156,153,150,147,144,141,138,134,131, 128,125,122,119,116,112,109,106,103,100,97,94,91,88,85,82,79,76,73, 70,68,65,62,59,57,54,52,49,47,44,42,39,37,35,33,31,29,27,25,27,29,27,25,23,21, 19,18,16,15,13,12,11,9,8,7,6,5,4,4,3,2,2,1,1,0,0,0,0,0,0,0,0,1,1,2, 2,3,4,4,5,6,7,8,9,11,12,13,15,16,18,19,21,23,25,27,29,31,33,35,37, 39,42,44,47,49,52,54,57,59,62,65,68,70,73,76,79,82,85,88,97,94,97
