C++ 如何连接二进制宏值？什么是二进制类型？

正在处理使用二进制命令代码的arduino项目

采样率和过滤器类型是两个串联的代码。 采样率=MSB一半，过滤器类型=LSB一半

发现：

这将是完全相同的代码。宏将被二进制文字替换，文字将被提升为整数，然后将调用左移位和or运算符。

欢迎使用堆栈溢出。请阅读，采取，阅读，以及。最后，请学习如何创建（代码）。尽可能避免宏，尤其是当你在C++中编码的时候，有更好的方法来做这样的事情。@ MarekR真是一个莫名其妙的评论。很明显，宏来自外部源。AFAIK Arduino Uno有16位int。使用AdaFruit“Arduino”nRF52832

#include <stdio.h>
int main() {

    int first = 0b1010;
              //^^v See here
    int second = 0b0011;
    int result = (first << 4) | second;
    printf("%d", result);

    return 0;
