uint16_t

STM32里的类型定义,见如下说明: /* Exported types ------------------------------------------------------------*/ typedef signed long s32; typedef signed short s16; typedef signed char s8; typedef signed long const sc32; /* Read...

uint_8与u8、uint16_t与u16、unit_32与u32没有区别 分别是 unsigned char unsigned int unsigned long int的不同写法

将变量t类型强制转换为uint8 *类型 也就是转换成指向uint8类型变量的指针变量 uint8应该是无符号8位二进制整型,其实就是unsigned char类型。

define的意思,是如果代码里有TIM_FLAG_Update,替换成(uint16_t)0x0001 (uint16_t)0x0001意思是,int16_t类型的十六进制的0001,

uint16_t的头文件stdint.h 那stdint.h在usb_regs.h头上被引用了吗?如果没有,要加上#include "stdint.h"

(((uint32_t)0x60020000) )是32位的IO地址(物理地址,硬件上设定的,不可修改) *(__IO uint16_t *)是读取该地址的参数值,其值为16位参数. 实际上是读取0x60020000寄存器的参数,或者可以说是这个IO口现在的状态.

STM32中DR寄存器只有低9位(8:0)有效,其余高位是保留的。所以在进行寄存器赋值时,为了保证正确性和将来的兼容性,只取Data的低9位数据。所以出现了USARTx->DR = (Data & (uint16_t)0x01FF);这样的语句,假设不小心Data高位有值也能保证寄存器...

如果你要用 TIMx->SR = (uint16_t)~TIM_FLAG; 表述 TIMx->SR=0xFFF7; 则需要 #define TIM_FLAG ((uint16_t)0x0008) 用你提供的两个flag ...
