在你的代码中，main()函数中缺少一对大括号，导致编译器无法识别你的函数定义。你需要在 t = 0x01; 的下一行加上一个左大括号 {，将其作为 F_KeySacnPro() 函数的开始，并将函数的结尾加上一个右大括号 }。

正确的 main() 函数和 F_KeySacnPro() 函数应该是这样的：

void F_KeySacnPro(void){
    if( !KEY_ONOFF )
    {                 
        R_KeyCount++;
        if( R_KeyCount >= 5 )
        {        
            if( !B_KeyFlag )
            {
                B_KeyFlag = 1;   //按键按下一次有效
                // while(1)
                {
                    for(i = 0; i < 10; i++)
                    {
                        //亮其中一个，且按照P2.0到P2.7的顺序点亮
                        if( t == 0x01 )
                        {
                            PORTB = 0x01;
                        }
