Design of multi

由于该源程序并非为单片机而编写，因此资源占用率很大，要想在C51中使用，还必须对其进行改造-because the source is not prepared for a microcontroller, the occupancy rate has great resources, in order to use the C51, we must transform its

MAX7219 LED显示驱动程序，本程序由C51系列单片机使用！keil环境开发！-MAX7219 LED display driver, the procedures by the use of C51 microcontroller series! Keil development environment!

CF8051F040开发板的SRAM_rw_test 程序-CF8051F040 development board

16x16LED 点阵屏源代码和电路图，可以实现上下移，左右移-Dot-matrix screen 16x16LED source code and schematics can be achieved on the lower left and right shift

LCD应用系统程序，里面有proteus仿真程序。-LCD application procedures, proteus simulation program there.

DIY多功能转换器（已调试通过）。 本原理图可以实现USB/RS232、USB/RS422、USB/RS485接口转换功能。只需安装USB驱动程序即可实现USB转串口的功能，简单方便。另外只需对电路图稍作改动即可实现RS232/RS422或RS232/RS485转换功能。 心动了吗？不如赶快行动，拥有属于自己的五合一的接口转换器吧！-DIY Multi-function Converter (has debug through). The schematic diagram can be achieved USB/RS232, USB/RS422, USB/RS485 interface conversion. Simply install the USB driver can achieve the function of USB to serial, easy and convenient. Also just to make a minor amendment to the circuit can be realized RS232/RS422 or RS232/RS485 conversion. Echocardiography it? Action as soon as possible, with their own-one interface converter吧!

单片机系统中的汉字显示 　　 摘要： 需要显示的汉字较多时，单片机系统中的汉字编码非常繁琐。本文介绍一种直接利用PC机的汉字内码作为单片机系统的汉字编码，以简化系统的设计。-SCM system of Chinese character display Abstract : The need to show the Chinese characters more, the SCM system of Chinese character coding very cumbersome. This paper presents a direct use of the PC as the Chinese character coding SCM Chinese character coding system to simplify system design.
