一段lcm06xk方面的液晶驱动代码，经过测试证实可用-For some aspects of lcm06xk LCD driver code has been tested to confirm availability

对基于splc501液晶控制器的128×64点阵的液晶驱动c51程序。包括一个自建字库。-right splc501 LCD Controller Based on the 128 x 64 dot-matrix LCD driver c51 procedures. Include a self-built character.

本人非常支持单片机设计DIY 在这里再次献出小弟的一点心意,下面是使用AT89S52驱动74HC4015,实现1选择8的数据通道切换器,可以在不8个通道出加上不同大小的电阻.可以用来单声道音量的大小控制. 下面作品图是小弟设计的廉价的 基于单片机的毕业设计 ,它还使用了无线接收发送模块,通过使用手上的遥控器能控制音量的大小,还加了一块HCF4052用于输入音道的选择,支持思路音频信号的输入,一路音频信号的输出: -I very much support the single-chip design DIY here again gave a little boy s mind is to use the following AT89S52 drive 74HC4015, to achieve a choice of 8 switches the data channel, you can not add the 8-channel resistance of different sizes. Can used to the size of mono volume control. The following work plan is designed小弟cheap graduation based on single-chip design, it uses the wireless receiver send module, through the use of the hands of the remote control can control the volume size, but also Add a piece of HCF4052 Road for the importation of sound choices, to support the idea of audio signal input, the output audio signal all the way:

程序描述：这个范例说明如何使用8051，以及汇编语言的程序连结， 当我们按下向上数的按钮之后，程序就会把0到9的共 阳7段显示器字型码存入AT93C46；如果我们按下向下 数的按钮之后，程序就会把9到0的共阳7段显示器字 型码存入AT93C46。 程序每一次重新开始执行时(Power on 或是Reset)，8051 会先从AT93C46当中读出最前面的10个位组，然后 就反复地将这10个位组的数据经由PORT 1送到1个 共阳七段显示器。*/-Procedure Description: This example shows how to use the 8051, as well as links to assembly language programs, when we pressed up a few of the button, the program will bring a total of 0-9 yang seven segment display font yards into AT93C46 if we press Next down the number button, the program will bring a total of 9-0 Yang seven segment display font code into AT93C46. Process to begin again each time when the (Power on or Reset), 8051 will start with AT93C46 were read out in front, 10-bit groups, and then repeated these 10-bit groups of data via the PORT 1 sent to a A total of seven-segment display Yang.* /
