众说纷纭的 C 语言回调函数到底是什么鬼?这里有最好的解答!
众说纷纭的 C 语言回调函数到底是什么鬼?这里有最好的解答! 1. 什么是回调函数? 回调函数,光听名字就比普通函数要高大上一些,那到底什么是回调函数呢?恕我读得书少,没有在那本书上看到关于回调函数的定义。我在百度上搜了一下,发现众说纷纭,有很大一部分都是使用类似这么一个场景来说明:A君去B君店里买东西,恰好缺货,A君留下号码给B君,有货时通知A君。感觉这个让人更容易想到的是异步操

CC1310直接操作寄存器编程
官方 CC13x0 提供的驱动为了兼容多种器件和操作系统比较抽象,例如串口发送函数是这样的: int_fast32_t UART_write(UART_Handle handle, const void *buffer, size_t size) {     return (handle->fxnTablePtr->writeFxn(handle, buffer, size)); }

为什么电流和磁传感器对TWS(真无线耳机)的设计至关重要?
      TWS(True Wireless Stereo,真无线耳机)正在耳机市场中快速崛起。现在,用户在使用流媒体设备时不必再为耳机线的缠绕问题而困扰了。真无线耳机是基于Bluetooth?的无线耳机,其左右通道被分离成独立又相互配对的两个个体。尽管这种创新设计使用户不再需要用线连接手机或其它设备,但这给耳机制造商带来了一系列新的设计挑战。   为了最大限度地延长电池寿命和电池运行时间,耳

开关电源纹波,抑制或减少的5种方法
纹波,理论上和实际上都是一定存在的。通常抑制或减少它的做法有5种: 1、加大电感和输出电容滤波 根据开关电源的公式,电感内电流波动大小和电感值成反比,输出纹波和输出电容值成反比。所以加大电感值和输出电容值可以减小纹波。 同样,输出纹波与输出电容的关系:vripple=Imax/(Co×f)。 可以看出,加大输出电容值可以减小纹波。 通常的做法,对于输出电容,使用铝电解电容以
