在编译sd卡程序是出现以下错误，错误程序如下，求各位大侠帮助解决以下，谢谢啦

//发命令到SD卡
void SdCommand(u8 command, u32 argument, u8 CRC)
{
SdWrite(command|0x40);
SdWrite(((unsigned char *)&argument)[0]);
SdWrite(((unsigned char *)&argument)[1]);
SdWrite(((unsigned char *)&argument)[2]);
SdWrite(((unsigned char *)&argument)[3]);
SdWrite(CRC);
}

有一些.H文件没有调用，你写的函数和外部声明的不一样，入口参数也不对。

1）"delay，trials这两个变量申明了，但是没有定义
2）"int" is incompatible with parameter of type " (*)(CRC_TypeDef *)"，这个问题肯定是一个头文件没有包含，所以CRC_TypeDef *没有定义
3）90: function returning function is not allowed
User\SD.c: void SdCommand(u8 command, uc32 argument, u8 CRC)这个应该是函数中的return 有语法错误，函数申明为void类型的返回值

User\SD.c(170): error: #167: argument of type "int" is incompatible with parameter of type " (*)(CRC_TypeDef *)"
这个错误是处在 SdWrite(((unsigned char *)&argument)[0]);这个函数中，好好检查一下就能找到。

返回数据类型错误，"CRC_TypeDef *" 与"unsigned char"
等参数类型不相匹配，可以尝试强制转换或修改其中的数据类型以求一致

stm32 keil4 平台下 spi方式 sd卡读写程序 ，做一个demo
给你吧，参考一下，多想一点，有收获！
