1. COM1
#define COM1LINUX "/dev/ttyS0"

#define COM2LINUX "/dev/ttyS1"

#define COM3LINUX "/dev/ttyS2"

#define COM4LINUX "/dev/ttyS3"

#define COM5LINUX "/dev/ttyS4"

#define COM6LINUX "/dev/ttyS5"

 

#define COM1WR703N "/dev/ttyATH0"

#ifdef WR703N

COMReceive(COM1WR703N, "$1234567890");

#else

  COMReceive(COM1LINUX, "$1234567890");

#endif

启动信息:

Serial: 8250/16550 driver, 1 ports, IRQ sharing disabled

ar933x-uart: ttyATH0 at MMIO 0x18020000 (irq = 11) is a AR933X UART

console [ttyATH0] enabled, bootconsole disabled

路由器启动时COM波特率为115200

rc = tcgetattr (fd[portnum], &t);//虚拟机成功返回0, 但在路由器上返回-1. 解决:WR703N=/dev/ttyATH0

echo "test" > /dev/ttyATH0//路由器上执行此命令, 串口监视端可看到 test

TP_IN为RX,TP_OUT为TX,Micro USB口的数据接口为空,TTL与Micro USB共用GND接口。从而实现免拆机无损TTL改造。

引出后黑色为GND,绿色为RX,白色为TX。完成焊接后请务必检查个个电缆链接且独立。

排列: 黑白绿(Err), 黑绿白(OK), 靠近RJ45接口为黑线. 


2. 屏蔽串口的系统显示
PC端用串口调试时, 能正常接收到数据, 但发送数据时出现 BusyBox 的提示, 而且导致路由器端数据接收不稳定. 

BusyBox v1.18.5 (2011-09-18 11:2  _______                     ________        __

 |       |.---@OpenWrt:/#

Please press Enter to activate this console.

解决: vi /etc/inittab

::sysinit:/etc/init.d/rcS S boot

::shutdown:/etc/init.d/rcS K shutdown

ttyS0::askfirst:/bin/ash --login

#ttyATH0::askfirst:/bin/ash --login  #注释此行


3. 增加了UDP调试
#define DEBUGP UDPprintf
DEBUGP("UARTHandler: %d, Len = %d, %s\n", usTimes, usLen, pcString);

4.  增加了TCP调试

#define DEBUGP TCPprintf

DEBUGP("UARTHandler: %d, Len = %d, %s\n", usTimes, usLen, pcString);

5. TCP转COM, 同时UDP做Debug的数据显示




6. 获取本地时间

#include

struct tm  *GetLocalTime(void)

{

time_t now;

struct tm  *timenow;

 

time(&now);

timenow = localtime(&now);

 

//DEBUGP("Time = %d-%d-%d %d:%d:%d\n", timenow->tm_year+1900, timenow->tm_mon+1, timenow->tm_mday,

//timenow->tm_hour, timenow->tm_min, timenow->tm_sec);

//DEBUGP("recent time is : %s \n", asctime(timenow));

}

12-5-22:  修改 uhttpd, 增加自定义的SSI

opkg install /tmp/uhttpd_31_ar71xx.ipk

/etc/init.d/uhttpd stop

/etc/init.d/uhttpd start


修改 xuudp.c ,  接收到的HTTP请求


看看以前做的个网页控制的小东东, 准备移植到路由器上


12-5-29: C实现的发送文本邮件, 发送附件尚未实现.

int main(int argc, char* argv[])

{

char to_id[100], subject[100];

char pcMailText[1000];

static int times=1;

 

sprintf(to_id, "%s", "onewire@126.com");

sprintf(subject, "%s %d", "Linux test mail", times++);

sprintf(pcMailText, "%s", "秋水在路由器上实验, Linux下C编程:眼神带着淡淡的倦意,轻轻的忧惺,宛若远山含笑迷蒙,但又如闪电惊雷般动人心魄");

SendMail(to_id, subject, pcMailText);

 

system("uname -r");

}

--- 测试OK的 base64加密,

static const char g_base64_chars [] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";

void _encode_block ( u_char in[3], u_char out[4] )

{

 out[0] = g_base64_chars [ ( in[0] >> 2 ) ];

 out[1] = g_base64_chars [ ( ((in[0] & 0x03) << 4)  | ((in[1] & 0xf0) >> 4) ) ];

 out[2] = g_base64_chars [ ( ((in[1] & 0x0f) << 2)  | ((in[2] & 0xc0) >> 6) ) ];

 out[3] = g_base64_chars [ ( in[2] & 0x3f ) ];

}

 

void encode_base64(u_char* output, u_char* input)

{

 int inputlen = strlen(input);

 

 while ( inputlen >= 3 ) {

_encode_block ( input, output );

inputlen -= 3;

input    += 3;

output   += 4;

 }

 

 if ( inputlen > 0 ) {

  u_char temp[3];

 

  memset ( temp, 0, sizeof(temp) );

  memcpy ( temp, input, inputlen );

 

  _encode_block ( temp, output );

  output[3] = '=';

  if ( inputlen == 1 )

   output[2] = '=';

 

  output += 4;

 }

 

 output[0] = 0;

}


调用例程:

encode_base64(wkstr, FROMID);

strcat(wkstr, "\r\n");

send_socket(wkstr);//用户名的base64编码
