本人编写的CS3758DEMO测试程序，CS3758主要用于5.1CH电子音量控制，兼容PT2258-I CS3758DEMO prepared by the test procedure CS3758 mainly for 5.1 CH electronic volume control, compatibility PT2258

其中k1-k5,5个分程序可以单独执行，在k0程序中以子程序出现，注意：每个 程序作为子程序后，加上ret,去掉ljmp-Where k1-k5, 5 sub-programs can be individually implemented programs to subroutines in k0 appear NOTE: each program as a subroutine, coupled with the ret, remove ljmp

验证码控件,附属性就可以运行,不错的一个工具,试试看.-validation code Controls subsidiary on the run, a good tool, and see what happens.

伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路，输出-8V至+8V电压，控制直流电机。改变输出电.压值，改变电机转速，用8255 的PB.0 读回脉冲计数，计算电机转速。在电压允许范围内，直流电机的转速随着电压的升高而加快，若加上的电压为负电压，则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压，将电压经驱动后加在直流电机上，使其运转。通过单片机输出数据到D/A变换电路，控制电压的高低和正负，观察电机的旋转情况。 在电机转盘上安装一个小磁芯，用霍尔元件感应电机转速，用单片机控制8255读回感应脉冲，从而测算出电机的转速。 -err
