用I/O口实现NAND flash 的读写?

[blue_coco]

各位大虾, 谁有全C的程序啊,或者推荐个好网站.

找个芯片看看数据手册就好了。

多谢各位了,有没有代码参考一下.

[icesnows]

么得代码参考一下

[blue_coco]

不会没人用过吧

ningxin(资深民工) 的那个帖已经相当全面了,如果你看不懂那个,给你全代码也是白搭,可能你根本就不知道从哪里下手去改代码~~

现在完善的代码都是要收钱的。

NAND FLASH 是什么芯片的？

void WriteCmd(unsigned char cmd)
{
nandPortD = 0xFF;
ClsLine(nandSPortO,nandALE);
ClsLine(nandSPortO,nandnCE);
SetLine(nandSPortO,nandCLE);
ClsLine(nandSPortO,nandnWE);
nandPortO = cmd;
SetLine(nandSPortO,nandnWE);
ClsLine(nandSPortO,nandCLE);
SetLine(nandSPortO,nandALE);
}

void WriteByte(unsigned char Wdata)
{
nandPortD = 0xFF;
SetLine(nandSPortO,nandnWE);
ClsLine(nandSPortO,nandCLE);
ClsLine(nandSPortO,nandnCE);
ClsLine(nandSPortO,nandALE);
ClsLine(nandSPortO,nandnWE);
while((nandSPortI & nandRnB) != nandRnB); // wait busy end
nandPortO = Wdata;
while((nandSPortI & nandRnB) != nandRnB); // wait busy end
SetLine(nandSPortO,nandnWE);
}

unsigned char ReadByte(void)
{
unsigned char Rdata;
nandPortD = 0x00;
SetLine(nandSPortO,nandnWE);
ClsLine(nandSPortO,nandCLE);
ClsLine(nandSPortO,nandALE);
ClsLine(nandSPortO,nandnCE);
ClsLine(nandSPortO,nandnRE);
while((nandSPortI & nandRnB) != nandRnB); // wait busy end
Rdata = nandPortI;
while((nandSPortI & nandRnB) != nandRnB); // wait busy end
SetLine(nandSPortO,nandnRE);
return Rdata;
}
