u8,u16,u32都是C语言数据类型,分别代表8位,16位,32位长度的数据类型,一个字节是8位,所以u8是1个字节,u16是2个字节,u32是4个字节。 可以在stm32库头文件中找到数据类型的声明 在stdint.h中: typedef unsigned char uint8_t; typedef unsigned short uint16_t; typedef unsigned long uint32_t; 在stm32...
MAX_S宏内(void)(&_x == &_y)语句用于检查参数类型一致性。当参数x和y类型不同时,会产生” comparison of distinct pointer types lacks a cast”的编译警告。 注意,MAX_S和TMAX_S宏虽可避免参数副作用,但会增加内存开销并降低执行效率。若使用者能保证宏参数不存在副作用,则可选用普通定义(即MAX宏)。

1.头文件(Header Files):C语言标准库包含一系列的头文件,用于声明函数原型、定义常量和数据类型等。开发者可以通过包含适当的头文件来使用标准库中提供的函数和类型。 2.静态库(Static Libraries):C语言标准库还以静态库的形式提供,其中包含了标准库函数和类型的实现代码。静态库是在编译时与应用程序一起链接,使得...
Use<stdint.h>(uint8_t, int32_t etc). Use the smallest required scope. Variables in a file (outside functions) are always static. Avoid to use global variables (use functions to set/get static variables). # &,* is aligned to names, e.g.,uint32_t *pAddress ...

每像素位数通常为 1、4、8、16、24 或 32。 有关此值的详细信息,请参阅 Windows SDK 中 BITMAPINFOHEADER 的biBitCount 成员。CImage::GetColorTable从DIB 节调色板的条目范围检索红、绿、蓝 (RGB) 颜色值。C++ 复制 void GetColorTable( UINT iFirstColor, UINT nColors, RGBQUAD* prgbColors) const ...
intrinsics 指令的示例如下,一次执行 8 个 float 值的加法。 int main() { __m128 v0 = _mm_set_ps(1.0f, 2.0f, 3.0f, 4.0f); __m128 v1 = _mm_set_ps(1.0f, 2.0f, 3.0f, 4.0f); __m128 result = _mm_add_ps(v0, v1); ...
char_16_t and char32_t You can no longer use char16_t or char32_t as aliases in a typedef, because these types are now treated as built-in. It was common for users and library authors to define char16_t and char32_t as aliases of uint16_t and uint32_t, respectively. C++ Cop...
