传一个我们项目中用到得Modbus程序，这是已经调试好的用的芯片是MSP430FE425。希望能对大家有用。-Biography of a project, we used a Modbus process, which is already used for debugging the chip is good MSP430FE425. Useful for all of us hope.

电子琴 1． 实验任务 　1． 由 4X4 组成 16 个按钮矩阵，设计成 16 个音。 　2． 可随意弹奏想要表达的音乐。-a flower. An experimental tasks. Formed by the 4x4 matrix button 16, 16 designed to sound. 2. Free expression want to play the music.

数字电压表,可模拟进行电压测量,用数码管显示电压值,有图和程序-Digital voltage meter, can be simulated for voltage measurement, digital display voltage value, a plan and procedures

利用单片机产生pmw，控制led，修改后可控制直流电机-Single-chip computer generated pmw, control led, modifications can be controlled DC motor

我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大 致如下： 电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自 动切换量程，也可手动切换。 另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）； 还可以产生几个单点频率的方波信号（比如1KHz）。 采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用 每次开机重新设置。可单5V供电，也可9V交流供电 -I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be

我同事做的一个CS5522的51单片机的驱动,用的是89S52,开发环境是KEIL C-my colleagues do a CS5522 51 MCU-driven, with the 89S52. Development environment is KEIL C

单片机控制电动机的运转，使电动机向一个方向逐渐加速，然后减速，然后在向另一个方向逐渐加速，再减速，如此循环下去。-Microcontroller to control the motor operation, so motor to accelerate gradually in one direction, then slow down, and then a gradual acceleration in the other direction, then slow down, and so cycle continues.
