（1）i2c

#define I2C_READ_REG_BYTE(reg) (*(volatile unsigned char *)(reg))
#define I2C_READ_REG_WORD(reg) (*(volatile unsigned short *)(reg))
#define I2C_READ_REG_LONG(reg) (*(volatile unsigned int *)(reg))

#define I2C_WRITE_REG_BYTE(val, reg) (*(volatile unsigned char *)(reg) = (val))
#define I2C_WRITE_REG_WORD(val, reg) (*(volatile unsigned short *)(reg) = (val))
#define I2C_WRITE_REG_LONG(val, reg) (*(volatile unsigned int *)(reg) = (val))

#define是预处理命令, 用来对关键字进行文本替换, 这里是不带参数的简单替换
把代码中I2C0CONSET替换为(*((volatile unsigned char *) 0xE001C000))

(volatile unsigned char *)括号里是类型, 是强制类型转换
把0xE001C000转换为这个类型的指针
指针除了要有地址,还要有地址里数据的类型, 没有类型的话计算机不知道是要读2个字节还是4个字节,也不知道是无符号还是有符号等等

volatile 是告诉编译器变量的值可能在不知道的情况下改变,防止编译器自动优化

再前面的*是指针解引用, 指针是unsigned char*的, 地址是0xE001C000, 解引用后就是0xE001C000里存的unsigned char值
