单片机编程 基于C8051F060单片机控制AD9833实现FSK调制
引言
在数字信息传输中，基带数字信号通常要经过调制器调制，将频率搬移到适合信息传输的频段上。2FSK就是用数字信号去调制载波的频率（移频键控），由于它具有方法简单、易于实现、抗噪声和抗衰落性能较强等优点，因此在现代数字通信系统的低、中速数据传输中得到了广泛应用。
直接数字频率合成技术(DDS)将先进的数字处 ...
技术资料 项目教学法在单片机实践教学中的应用
近些年,随着我国科学技术的快速发展,社会各行各业对人才实践能力提出了更多更高的要求,所以当前完善单片机实践教学具有较大的可行性。但从现阶段单片机实践教学基本现状来看,其还存在较多问题,致使学生学习实践能力难以得到有效提升。因此,相关教育工作者要直面单片机实践教学困境,结合教学内容合理融入项目教学法,提升教学 ...

For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...
单片机编程 PCA9516 5channel I2C hub
The PCA9516 is a BiCMOS integrated circuit intended forapplication in I2C and SMBus systems.While retaining all the operating modes and features of the I2Csystem, it permits extension of the I2C-bus by buffering both the data(SDA) and the clock (SCL) lines, thus enabling five buses of 400 pF.The I2C ...

测试测量 能量收集系统的设计挑战
Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many ...
