单片机做的小键盘，单片机模拟ps2接口的程序-Singlechip make a small keyboard, single-chip analog interface procedures ps2

这个是我的LC698S评估板图,希望大家参考!-this is my SBC Evaluation map, we hope reference!

利用单片机加控制直流电机，利用P1口，编制程序输出一串脉冲，经放大后驱动小电机，改变输出脉冲的电平及持续时间，达到使电机正转、反转、加速、减速。停转之目的。 可以通过74LS244输入开关量数据来控制小直流电机的转动，实现正转四种转速，反转四种转速及停转。 -The use of SCM in controlling the DC motor

本软件为7279显示控制器软件，用KEIL 7。0编写。-software for the 7279 display controller software, used KEIL 7. 0 prepared.

一个简单的程序，但是是我入门的时候写的，还不错-a simple procedure, but it is when I start to write, but also good

关于msp430单片机的一些 自己收集的一些有需要的请下载-MSP430 MCU on some of his own collection of some of those in need, please download

* The keyboard is assumed to be a matrix having 4 rows by 6 columns. However, this code works for any * matrix arrangements up to an 8 x 8 matrix. By using from one to three of the column inputs, the driver * can support "SHIFT" keys. These keys are: SHIFT1, SHIFT2 and SHIFT3.
