enc28j60 控制多个 led IO 的代码，模块本身带控制的html页面
本帖最后由 布列松 于 2015-5-3 22:29 编辑原标题：请问这段串口代码，我想输出两组不同的数据，怎样改呢
enc28j60 控制多个 led IO 的代码，模块本身带控制的html页面，非常感谢，tsaiwn，的热心帮忙，代码我去掉了 rs485的串口控制输出，html页面加上了中文的显示。对了，后来发现经常死机的原因可能是主板的质量不好引起的，这种山寨主板，我居然在这段时间烧了两块（夏天来了？），都是串口烧了，主芯片确还正常。

如果只是固定的两组数据，就再声明一个数组
unsigned char hexdata 这部分是一样的，只是里面的代码不一样而已，怎么办呢 不太清楚你的意图
可以使用二维数组
unsigned char hexdata[ ] = {0x40,0x07,0x00 };
unsigned char gg[ ] = { 65, 66, 67 }; // 'A', 'B', 'C'
unsigned char yy[ ] = { 97, 0x31, 0x33, 0x35, 0, 0, 0x0D}; // 'a', '1', '3', '5', ..
//...
Serial.write(hexdata, sizeof(hexdata) );
Serial.write(gg, 3 );
Serial.write(yy, sizeof(yy) );

unsigned char hexdata[ ] = {0x40,0x07,0x00 };
不好意思，这些什么意思，不是很明白 tsaiwn 发表于 2015-4-10 23:06 static/image/common/back.gif
unsigned char hexdata[ ] = {0x40,0x07,0x00 };
对了，一定是 8个的 tsaiwn 发表于 2015-4-10 23:06 static/image/common/back.gif
unsigned char hexdata[ ] = {0x40,0x07,0x00 };
这样不行的 tsaiwn 发表于 2015-4-10 23:06 static/image/common/back.gif
unsigned char hexdata[ ] = {0x40,0x07,0x00 };
我修改了一下，虽然可以上传成功，但是我要的一定要全部是 hexdata 16位数据 布列松 发表于 2015-4-10 23:44 static/image/common/back.gif
这样不行的
奇怪
你爱写几个就几个
你写八百个计算机也不会说不行 !
我只是告诉你
可以不必去数
用 sizeof( arraay_name ) 叫计算机自己帮你数即可

要八个你就自己写八个就是了

要 hex 你就自己写 0x??
反正对计算机来说
以下三个完全一样:
unsigned gg[ ] = {'A', 'B', 'C' };
unsigned gg[ ] = {65, 0x42, 'C' };
unsigned gg[ ] = {0x41, 66, 'C' };

以下三个完全一样:
这就是我现在的代码，第一段的：
unsigned char hexdata = {0x01,0x05,0x00,0x10,0xFF,0x00,0x8D,0xFF};
实现起来有效的，
但第二段：
unsigned char yy[] = {0x01,0x05,0x00,0x10,0x00,0x00,0xCC,0xFF};
是无效的。
#include <EtherCard.h>

Serial.write(hexdata, 8);
ledStatus = true;
}
if(strstr((char *)Ethernet::buffer + pos, "GET /?status=OFF") != 0) {
Serial.write(yy,sizeof( yy ));
ledStatus = false;
}
if(ledStatus) {
digitalWrite(ledPin, HIGH);
statusLabel = on;
buttonLabel = off;
} else {
digitalWrite(ledPin, LOW);

unsigned char hexdata = {0x01,0x05,0x00,0x10,0xFF,0x00,0x ...
第一段改：
unsigned char hexdata[] = {0x01,0x05,0x00,0x10,0xFF,0x00,0x8D,0xFF};
//...
用Serial.write(hexdata, sizeof(hexdata) );
实现起来也是有效 !!
第二段无效是別的原因 !
