24L01發(fā)送程序1138IO模擬移植

STM32寄存器多多，所以決定用回AVR結(jié)果發(fā)現(xiàn)AVR的穩(wěn)定性非常值得懷疑。首先就是內(nèi)部參考電壓用不到，2片MEGA16結(jié)果有一片用不了內(nèi)部參考電壓（PS電路程序完全一樣，而且外部REF是懸空不會(huì)導(dǎo)致內(nèi)部短路），不過這個(gè)就原諒它了。編程CTC模式，結(jié)果發(fā)現(xiàn)1S中斷的程序竟然有時(shí)進(jìn)可以運(yùn)行有時(shí)不可運(yùn)行（這中情況在重插電源時(shí)交替發(fā)生，后來(lái)就干脆一直進(jìn)不了中斷），還有一芯片一個(gè)不小心燒錯(cuò)時(shí)鐘溶絲，連續(xù)都讀不出東西更別說下載了，不過突然間有下得了，之后又下載不了。。。所以覺得還是用51好，要是當(dāng)初用匯編學(xué)51再用增強(qiáng)型51那可能爽很多，，。
