【正文】 基本掌握了Protel99SE原理圖的方法，并設(shè)計(jì)了一個(gè)單片機(jī)最小系統(tǒng)。了解了單片機(jī)方面的先進(jìn)技術(shù)，這些都為我的未來(lái)的學(xué)習(xí)指明了方向。通過(guò)這次畢業(yè)設(shè)計(jì)，我學(xué)到了不少課本上沒(méi)有的知識(shí)，也鍛煉了自己的動(dòng)手能力，將以前學(xué)過(guò)的零散的知識(shí)串到一起。 do { keycode=Get_Key()。 } }void timer1(void) interrupt 3 using 1{buz=~buz。 if(P3==0x7f) continue。 TR0=0。 stl=yinfu1[(Music_hzcb[j]%100)/101][((Music_hzcb[j]%10)1)*2+1]。 Music_hzcb[j]!=0xff。 }return 8。temp=P1。 ET1=1。j0。i0k。unsigned char sth,stl。unsigned char code Music_hzcb[]={ 0x17,0x02, 0x17,0x03, 0x18,0x03, 0x19,0x02, 0x15,0x03,0x16,0x03, 0x17,0x03, 0x17,0x03, 0x17,0x03, 0x18,0x03,0x19,0x02, 0x16,0x03, 0x17,0x03, 0x18,0x02, 0x18,0x03,0x17,0x03, 0x15,0x02, 0x18,0x03, 0x17,0x03, 0x18,0x02,0x10,0x03, 0x15,0x03, 0x16,0x02, 0x15,0x03, 0x16,0x03,0x17,0x02, 0x17,0x03, 0x18,0x03, 0x19,0x02, 0x1A,0x03,0x1B,0x03, 0x1F,0x03, 0x1F,0x03, 0x17,0x03, 0x18,0x03,0x19,0x02, 0x16,0x03, 0x17,0x03, 0x18,0x03, 0x17,0x03,0x18,0x03, 0x1F,0x03, 0x1F,0x02, 0x16,0x03, 0x17,0x03,0x18,0x03, 0x17,0x03, 0x18,0x03, 0x20,0x03, 0x20,0x02,0x1F,0x03, 0x1B,0x03, 0x1F,0x66, 0x20,0x03, 0x21,0x03,0x20,0x03, 0x1F,0x03, 0x1B,0x03, 0x1F,0x66, 0x1F,0x03,0x1B,0x03, 0x19,0x03, 0x19,0x03, 0x15,0x03, 0x1A,0x66,0x1A,0x03, 0x19,0x03, 0x15,0x03, 0x15,0x03, 0x17,0x03,0x16,0x66, 0x17,0x04, 0x18,0x04, 0x18,0x03, 0x19,0x03,0x1F,0x03, 0x
