1、单向通信 向甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；并将a的值取反从P0口输出，控制D0、D1、D2、D3相应点亮。乙方接收到数据并偶校验正确后，将接收数据取反从P0口输出，控制D0、D1、D2、D3相应点亮。 2、双向通信 甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；乙方未按键不发送，按键后将乙方按键得到的a*16发送；甲乙双方都将发送数据与接收数据相或后再取反，从P0口输出控制D0—D7相应点亮。 3、间隔发送 未按键，甲方不发送数据，按键后甲方每隔50ms连续发送4个字节：0xff、a、a、a。 乙方只在收到甲方数据0xff后的3个数据并验证相同时，才将接收数据*16发送。 甲乙双方都将发送数据与接收数据相或后，从P0口输出控制D0—D7相应点亮。(1. One-way communication The value of variable a is continuously sent to Party A without key, a = 0x0f. After the key is pressed, the value of a is determined according to the key; and the value of a is output from P0 port to control the corresponding lighting of D0, D1, D2 and D3. After receiving the data and checking it correctly, Party B will output the received data from P0 port and control D0, D1, D2 and D3 to light up accordingly. 2. Two-way communication Party A continuously sends the value of variable a without key, a = 0x0f, and determines a value according to the key after the key; Party B does not send the key without key, and sends the a*16 obtained by the key after the key is pressed; Both parties will send the data to or from the receiving data, and then retrieve the data and control D0-D7 from the P0 port to light up accordingly. 3. Interval Sending Without keys, Party A does not send data. After keys, Party A sends 4 bytes continuously every 50 ms: 0xff, a, a.)

说明：  编辑框是常用控件之一，同时也是一种完全自实现较为繁琐的控件。本例实现了对编辑框的简单的自绘制，在保留其自身的强大功能的前提下，实现了编辑框的边框、背景、文字颜色以及禁用态的各种颜色的替换。 要想重绘，我们必须知道要绘什么。通过观察默认的编辑框我们可以很清楚的看到编辑框有三个最基础的部分需要我们绘制，他们分别是3D边框、背景和文字，再进一步分析我们会发现他们是一个基本窗口的两个部分，即客户区和非客户区。这样一来我们就知道应该用什么函数有针对性的绘制什么区域了，由于提供了源码，这里仅就基本原理和技术细节加以讨论，不过多地罗列代码。(Editor box is one of the common controls, and it is also a kind of control which is completely self-realization and tedious. This example realizes the simple self-drawing of the edit box, and realizes the replacement of the border, background, text color and various colors of the disabled state of the edit box while retaining its powerful function. To redraw, we must know what to draw. By observing the default edit box, we can clearly see that there are three most basic parts of the edit box that we need to draw. They are 3D border, background and text. Further analysis shows that they are two parts of a basic window, namely, client area and non-client area. In this way, we know which function should be used to draw which area. Since the source code is provided,)
