LPT控制下的MCS-51实现A/D转换

Using MCS-51 for A/D Converting under Control of LPT

在PC图形用户界面下 ,选择多个通道及多种频率的采样模式 ,经并口发送命令给MCS - 5 1,控制MAX -180芯片对模拟信号进行A/D转换 ,并将采集到的数据仍由并口传回PC的硬盘以供分析。

With PC's GUI, multi-channel and multi-frequency sample modes can be chosen; command to MCS-51 through LPT to control MAX-180 for A/D converting can be issued and transference of the data back to PC's hard disk can be done.
