大家好！我是菜鸟，目前在学单片机特别崇拜尤小翠大师的这篇单片机的逆变器http://bbs.dianyuan.com/topic/916798，我看了N遍程序终于能看懂一点点了，但是我没有现成的STC12C5410AD的单片机，但手中有一个STC12C5A60S2的单片机。我是想把STC12C5410AD的程序改为STC12C5A60S2用，我改了头文件后报错SPWM2 SPWM3，于是我根据程序对照2个单片机的PDF资料，发现自带AD中的寄存器也不同5410的ADC_DATA和5A60S2的RES不一样，我就把源程序呢里AD寄存器的ADC_DATA改为RES,具体修改的程序待会我贴出来。我是想问我这样修改程序为STC12C5A60S2可以直接用吗？同时希望有哪个高手有尤小翠的这程序的配套电路图吗？能给我一份吗？修改后的程序:
