若是定义了USE_FULL_ASSERT它,我们调用这个函数assert_param时,及对参数IS_GPIO_ALL_PERIPH(GPIOx)的正确性进行检查,通过一个C语言中的双目运算符来判断,若是返回1,执行语句(void)0,跟上面一样,若是返回0,则执行后面的函数assert_failed((uint8_t *)__FILE__, __LINE__),函数的作用在库函数中有解释,...
解析 意思是用IS_GPIO_ALL_PERIPH(PERIPH)代替(((PERIPH) == GPIOA) || ((PERIPH) == GPIOB) ||((PERIPH) == GPIOC) || ((PERIPH) == GPIOD) || ((PERIPH) == GPIOE) || ((PERIPH) == GPIOF) || ((PERIPH) == GPIOG))到... ...
