Timer for the beginner to learn to understand SCM research

max187的读取操作 用1602来显示！-max187 with 1602 of the read operation to display!

在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求，而且具有了单片机的稳定性和成熟性，且控制能力强，是一种低成本，高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct

用MSP430F449 定时器A模拟的串口代码，C语言，已经测试通过-MSP430F449 timer A simulation using the serial code, C language, has been tested

在AVR单片机的控制下，通过WinAVR编译器和makefile的编写，在一个数码管上实时输出键盘输入的字符，当在键盘上按下某一个键时，在数码管上显示该键的值。如按下1时数码管显示1，按下F时数码管显示F。-control, through WinAVR compiler makefile and the preparation, in a real-time digital control keyboard input output of the characters, when pressed on the keyboard a button, digital tube revealed that the value of the bond. Touching 1:00 a Digital Display, when pressed F F Digital Display.
