//?Pwm?波的占空比的設(shè)置，?輸出兩路Pwm波，端口為?P0.0輸出0路波，P0.1輸出1路波（注：?輸出端口有交叉開(kāi)關(guān)控制，若有其他外部輸出控制，則輸出有變）?
//該程序有系統(tǒng)時(shí)鐘設(shè)置并使用了PLL，使用是請(qǐng)注意系統(tǒng)時(shí)鐘設(shè)置，否則PWm波周期有變
//我只增添了void?PwmChange?（float?duty_cycle0?float?duty_cycle1）;函數(shù)，其他為?琛哥所寫(xiě)?????
//已經(jīng)驗(yàn)證void?PwmChange?（float?duty_cycle0?float?duty_cycle1）;?確實(shí)可以改變PWM輸出???2013/7/30???
