汇编语言开发的各种实用程序，希望对大家有用！是第二个文件！-assembly language development of practical procedures in the hope that it may be useful right! It is the second paper!

点菜系统 内置很多功能，希望对嵌入式开发人员有用。-A la carte system, built a lot of features, and they hope to be useful for embedded developers.

使用89S52设计的电子钟，C51 编写，本例没有使用1302等时钟芯片，但本例完全具有时钟芯片的功能。比如基本的年月日，时分秒和星期功能，而且还有平闰年的天数自动补偿。由于采用的是全软件算法，时钟误差较大，采用高质量晶振可以减少误差。本例重在培养与训练初学者对C51的学习。-89S52 designed using an electronic clock, C51 preparation, in this case did not use 1302 clock chip, etc., but in this case complete with a clock chip functions. For example the basic date, time, and every second week of features, but also the number of days flat leap automatic compensation. As a result of the full software algorithms, the clock error of greater use of high-quality crystal can reduce the error. In this case focuses on training and training for beginners to learn on the C51.

公司项目上曾经用过的DSP tms320c6713的bootloader程序，绝对可用，放心下载。通过CCS3.3编译好DEC6713_BOOT.out文件后，通过源码包内的convertTobin工具转换为bin，然后通过flash烧写工具将bin烧至DSP外扩的flash中。源码中包含了几种外设的驱动，使用6713的人可以作为参考。

使用miniGUI模拟器的简单开发例子(值得参考)-MiniGUI simulator used to develop a simple example (it is also useful)
