此程序为单片机和PC机RS232传输时候的C51源码!实现单片机中断程序发送,接受功能....

请将下载的2个插件内容拷贝到uVision 的安装目录下的 KeilC51BIN 中 2. 修改 Tool.ini, 此文件位于 uVision 的安装目录 keil 下. 请将下面的内容 添加到 [C51] 部分的后面. AGSI1=ledkey.dll ("ledkey") AGSI2=simboard.dll ("simboard") 3. 重启uVsion. 进入Debug 模式, 打开菜单Peripheral, 发现增加了2项 分别是键盘LED仿真板，51实验仿真板。-Please download the contents of two plug-ins are copied to the installation directory uVision under KeilC51BIN 2. Modify Tool.ini, this file is located in the installation directory uVision under keil. Please Add the following line to [C51] part of the back. AGSI1 = ledkey.dll (ledkey) AGSI2 = simboard.dll (simboard) 3. Reset uVsion. entered the Debug mode, open the menu Peripheral, found an increase of 2 are keyboard LED emulation board, emulation board 51 experiments.
