83390078DDS
- DDS的工作原理是以数控振荡器的方式产生频率、相位可控制的正弦波。电路一般包括基准时钟、频率累加器、相位累加器、幅度/相位转换电路、D/A转换器和低通滤波器(LPF)。频率累加器对输入信号进行累加运算,产生频率控制数据X(frequency data或相位步进量)。相位累加器由N位全加器和N位累加寄存器级联而成,对代表频率的2进制码进行累加运算,是典型的反馈电路,产生累加结果Y。幅度/相位转换电路实质上是一个波形寄存器,以供查表使用。读出的数据送入D/A转换器和低通滤波器。-DDS works
LED
- 动态LED点阵显示屏,此LED点阵显示屏是基于51单片,用595驱动,138级联扫描的,由于此类的资料网上很多,但是都没有一个拥有很详尽的说明,所以本人结合自己的实践以及整个测试的过程,给出整个代码详细的解释并分享自己总结出的经验(这些都包含在注释里了),希望对大家有用。 说明:附件里包含了代码和原理图(PROTEL DXP),只需回复就能下载了,希望大家支持。-Dynamic LED dot matrix display, the LED dot matrix display is
