本文介绍KEIL5编译器中遇到的#1295-D警告，详细解释了无参数函数声明未标明参数类型的问题，并提供了解决方案，即在函数声明中明确指定void参数。

KEIL5编译器报警告，警告内容如下：
#1295-D: Deprecated declaration I2C_Start - give arg types
警告原因无参数函数的函数声明没有标明参数为void型。
在函数声明中加入void即可。

//警告代码
void I2C_Start();
//修改后代码
void I2C_Start(void);

在声明函数时，如果该函数没有参数就要在括号里加“void” 例如 函数定义 void LED_GPIO_Init() {         GPIO_InitTypeDef  GPIO_Init_Struct;         GPIO_Init_Struct.GPIO_Pin    = LED_GPIO_PIN;         GPIO_Init_Struct.GPIO_Mode   = ...

warning:Deprecated declaration LaberPwmSel_High - give arg types解决方法

有些小伙伴在编译代码的时候偶尔会遇到这样的警告： 当然这对整体并没有什么影响，直接忽略也是ok的。 警告的大概意思是：LaberPwmSel_High() 应该提供类型声明。 也就是说，使用MDK编译器的时候，如果函数在定义时没有传参，要在括号中加void 由于我这个函数LaberPwmSel_High()没有传参，所以直接改成（void），再编译时就不会出现那个警告了。 ...
