2、那些原理，也不懂为什么那些程序的条件要那样限制，不过倒是大体上能明白主要的步骤写的是什么，有什么作用学单片。虽然学得是迷迷糊糊，但这并不妨碍我学习的积极性，从学单片机的过程中我明白到，在复杂的东西都是从简单的开始，也都是能学会的。在此学习的过程中，我以尽了最大的努力。文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档

34、定时器时间可设置为5ms中断一次。初始化完成后开中断，并进入主循环等中断。Mcu STC89C52、DIP404位数码管显示蜂鸣器4 个 LED 指示灯MAX232接口电路4 个独立式的按键系统复位电路电源接口电路为系统供电能晶振图 2.1.1 系统硬件结构框图开始文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编码:CE3B5H2A7N4 HO9Y1Z5W4G10 ZY3H1Q9Y7I6文档编
