STC单片机IO口模拟RS232测试程序,Keil Cx51应用开发技术中的程序主要的功能是在利用串口调试工具发送一个8bit的数据，而后单片机接收后把这个数据...

采用KEIL51编译,并在自己制作的板上运行过,具有很大的实用性-KEIL51 compiler used and produced in their own on-board run-off, and it is very practical

本文档详细的介绍了51单片机的程序设计方法-this document detailed account of the 51 Microcomputer Program Design

动力环境监控系统 动力环境监控系统-Dynamic driving force for environmental monitoring system environmental monitoring system

该设备可以循环检测24节2V6V12V蓄电池组，测量精度达0.05 ，测量结果通过RS485方式上传至主监控。采用MODBUS通讯协议。-The device can loop detection 24 2V 6V 12V battery, measurement accuracy of 0.05 , the measurement results through the RS485 upload to the main control means. Using MODBUS communication protocol.

非常之经典的MCS51程序,非常适合初学者-very classic MCS51 procedures, very suitable for beginners

用过采样和求均值技术提高模数转换器的分辨率.pdf-----针对目前单片机内嵌的模／数转换器的分辨率太低，而外接高分辨率成本又太高的情况，提出了用“过采样和求均值”的技术来使在有用的测量频带内的信噪比得到改善，从而提高测量的分辨. 率。并利用 60 - 7 0 /对其结论进行仿真，且在单片机上予以实现，结果表明测量分辨率明显提高。-Sampling and averaging techniques used to improve the resolution of ADC. Pdf----- targeted at the embedded microcontroller A/D converter resolution is too low, while the external high-resolution costs are too high situation, put forward with " Oversampling and Averaging" technology to make useful measurements in the frequency band signal to noise ratio to be improved, thereby enhancing the measurement resolution. rate. And a 60- 7 0/simulation of its conclusions, and in the SCM to be achieved, results show that the measurement resolution has improved significantly.
