..\HARDWARE\TIMER\timer.c(225): error: #268: declaration may not appear after executable statement in block

这个错误提示是因为在函数块内部，在已经有可执行语句的情况下，出现了变量或者函数的声明语句。

比如下面这段代码就会出现这个错误：

void test() {
  printf("hello world");
  int a = 10; // 这里出现了变量声明语句
}

解决方法是把变量或函数的声明语句放到函数块的开头，如下所示：

void test() {
  int a = 10; // 把变量声明语句放到函数块开头
  printf("hello world");
}

这样就可以解决这个错误了。

..\HARDWARE\TIMER\timer.c(78): error: #268: declaration may not appear after executable statement in block TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStructure;

这个错误是因为在函数块中已经有可执行的语句，而在此之后还有变量声明，导致编译器无法解析。解决方法是将变量声明放在函数块的开头，或者将变量声明提前到函数块外部。例如：

TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStructure; // 将变量声明放在函数块的开头

void timer_init() {
    // 初始化定时器
    TIM_TimeBaseInit(&TIM_TimeBaseInitStructure);
    ...
}

或者：

TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStructure; // 将变量声明提前到函数块外部

void timer_init() {
    // 初始化定时器
    TIM_TimeBaseInit(&TIM_TimeBaseInitStructure);
    ...
}

main.c(66): error C136: 'Timer0Server': 'void' on variable

This error message indicates that there is an issue with the variable "Timer0Server" in line 66 of the main.c file. Specifically, the error is stating that the variable has been declared as a void type, which is not valid.

To fix the error, check the declaration of the Timer0Server variable and ensure that it is declared with the correct data type. It should be declared as a pointer to a function with the appropriate parameters and return type.

For example, if Timer0Server is intended to be a function that takes no arguments and returns void, the declaration should look something like this:

void (*Timer0Server)(void);

Alternatively, if Timer0Server is intended to be a function that takes an integer argument and returns a float, the declaration should look something like this:

float (*Timer0Server)(int);
