简单粗暴的说: unit8_t,就是unsigned char, 数值范围是0-255, 占1个字节 unit16_t,就是unsigned int, 数值范围是0-65535, 占2个字节 unit32_t,就是unsigned long, 数值范围是0-4 294 967 295, 占4个字节编辑于 2022-05-09 20:48 内容所属专栏 Arduino系列 订阅专栏...

不同的平台会有不同的字长,所以利用预编译和typedef可以方便的维护代码。 typedef unsigned char uint8_t;//将uint8_t别名为无符号字符型 4、定义:在C99标准中定义了这些数据类型,具体定义在:stdint.h中 定义类型如下: typedef signed char int8_t; ...
