C51代码映射到arduino的问题

haliluya 发表于 2012-11-18 00:34:05

买了一个1.8的TFT模块，貌似商家只有C51的代码，技术支持也没有接触过arduino，只好自己动手改代码了。好在程序写的相当不错，可读性很好。可惜改写完后不能work，摸索了半天也没有进展，只好在这儿请高手指教，谢了！

下面是一个基础函数的代码，看看有没有什么问题。

// C51的代码, 管脚定义
// RESET=P1^0;
// A0 =P1^1;
// SDI=P1^2;
// SCK=P1^3;
// CS =P1^4;

void write_cmd(unsigned char addr1)
{
unsigned char bit8;

A0=0;
CS=0;
for(bit8=0;bit8<8;bit8++)
{
SCK=0;
if((addr1&0x80)==0x80)
SDI=1;
else
SDI=0;
SCK=1;
addr1=(addr1<<1);
}
CS=1;
}

// ------------------- 华丽的分割线 --------------------//

// 改成arduino的版本
unsigned int PIN_RESET=8;
unsigned int PIN_A0 =9;
unsigned int PIN_SDI=10;
unsigned int PIN_SCK=11;
unsigned int PIN_CS =12;

// 当然在setup()里面要设置
pinMode(PIN_RESET, OUTPUT);
。。。。。

void write_cmd(unsigned char addr1)
{
unsigned char bit8;

digitalWrite(PIN_A0, LOW); //PIN_A0=0;
digitalWrite(PIN_CS, LOW); //PIN_CS=0;
for(bit8=0;bit8<8;bit8++)
{
digitalWrite(PIN_SCK, LOW); //PIN_SCK=0;
if((addr1&0x80)==0x80)
digitalWrite(PIN_SDI, HIGH); //PIN_SDI=1;
else
digitalWrite(PIN_SDI, LOW); //PIN_SDI=0;

digitalWrite(PIN_SCK, HIGH); //PIN_SCK=1;
addr1=(addr1<<1);
}

digitalWrite(PIN_CS, HIGH); //PIN_CS=1;
}

另外注意到一个delay（）函数，【Crystal 】11.0592M/22.1184Mhz下为
void delay(unsigned int t)
{
unsigned int i,j;

for(j=0;j<t;j++)
for(i=0;i<250;i++);
}

这个函数直接用arduino的delay()函数替代，有没有问题呢？我的arduino板子是UNO。

水乐天写了一个51移植到Arduino的帖子，你参考下，看看有没有启发~

多谢指点。
又经过一天的调试，发现代码移植应该是对的，可惜由于某种未知原因，TFT仍然无法正常工作。这款TFT1.8只用5根线再加2根电源就可以驱动的，分辨率128x160，30圆左右，觉得蛮适合用arduino来玩的。我这儿贴一下淘宝链接：http://item.taobao.com/item.htm?id=17157919220，希望有同好能调通并分享，造福大家。

我的代码贴在下面，希望有帮助：
