三個(gè)單片機(jī)串行通信，1號(hào)從機(jī)和2號(hào)從機(jī)在p1口處個(gè)接八個(gè)按鍵, 主機(jī)p0口有八個(gè)燈，另外主機(jī)在p1.0和p1.1有兩個(gè)按鍵，第一個(gè)按鍵按下接通一號(hào)從機(jī)，當(dāng)1號(hào)從機(jī)有按鍵按下時(shí)候，主機(jī)p0對(duì)應(yīng)的燈亮，同理同理主機(jī)第2個(gè)按鍵按下 接通2號(hào)從機(jī)，當(dāng)2號(hào)從機(jī)有按鍵按下時(shí)候，主機(jī)p0對(duì)應(yīng)的燈亮
程序如下，在protues 里仿真一點(diǎn)沒(méi)反應(yīng)，請(qǐng)教下誰(shuí)能幫我看下程序錯(cuò)在哪里怎么改? 麻煩了 謝謝！！
