各位高手，
小女子现在在做一个毕业设计 是用pic16c745 然后连接一个usb到电路 再在visual studio2008里面做一个简单的GUI 这样在界面输入手机号码和信息 再一按发送键 指定的手机就能收到短信了！
我用visual studio写的vb程序 然后用MPLAB写的C++程序如下：
1.VB程序 仅有2个textbox和1个button而已
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ModemMode()
End Sub
Private Sub ModemMode()
If SerialPort1.IsOpen Then
SerialPort1.Close()
End If
SerialPort1.PortName = "COM1"
SerialPort1.BaudRate = 115200
SerialPort1.Parity = IO.Ports.Parity.None
SerialPort1.DataBits = 8
SerialPort1.StopBits = IO.Ports.StopBits.One
SerialPort1.RtsEnable = True
SerialPort1.Open()
SerialPort1.WriteLine("AT+CMGF=1" + vbCr)
WaitForm.ShowDialog()
TextBox1.Text = ""
TextBox1.Text = SerialPort1.ReadExisting
If InStr(TextBox1.Text, "OK") <> 0 Then
'MessageBox.Show("Successful(CMGF)!")
Else
'MessageBox.Show("Try again(CMGF)")
End If
TextBox1.Text = ""
SerialPort1.WriteLine("AT+CNMI=0,1,0,0,0" + vbCr)
WaitForm.ShowDialog()
WaitForm.ShowDialog()
TextBox1.Text = SerialPort1.ReadExisting
If InStr(TextBox1.Text, "OK") <> 0 Then
'MessageBox.Show("Successful(CNMI)!")
Else
'MessageBox.Show("Try again(CNMI)")
End If
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Call ToReadSMS()
End Sub
Private Sub ToReadSMS()
Dim txtSMS As Integer
Dim txtMessage As String
For txtSMS = 1 To 15
txtMessage = txtSMS
SerialPort1.WriteLine("AT+CMGR=" + txtMessage + vbCr) 'read message
System.Threading.Thread.Sleep(500)
TextBox1.Text = "" 'clear TextBox1
TextBox1.Text = SerialPort1.ReadExisting
SerialPort1.Close()
Next
End Sub
Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click
Call ToSendSMS()
End Sub
Private Sub ToSendSMS()
SerialPort1.WriteLine("AT+CMGS=" + txtPhone.Text + vbCr + Chr(26))
TextBox1.Text = vbNewLine & "....SMS Sending in progress..."
TextBox1.Refresh()
System.Threading.Thread.Sleep(750)
SerialPort1.WriteLine(Chr(26))
System.Threading.Thread.Sleep(5500)
TextBox1.Text = ""
TextBox1.Text = SerialPort1.ReadExisting
End Sub
Private Sub btnReset_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnReset.Click
txtPhone.Text = ""
txtMessage.Text = ""
End Sub
End Class
2.我在MPLAB里面写的 之前还没涉及到USB的问题 只是简单的做到 一按电路里的按钮 那个"HELLO"就发到我程序里写的手机号上
#include <htc.h>
#ifndef _XTAL_FREQ
#define _XTAL_FREQ 4000000
#endif
__CONFIG(WDTDIS&PWRTDIS&UNPROTECT&H4);
void Delay(int loop)
{
int i;
for(i=0;i<loop;i++);
}
void init(void)//Assign & Initialize PORTB I/0
{
PORTB=0x02;
TRISB=0x02;
}
void initUSART(void)//Initialize USART
{
TXSTA=0x22;
RCSTA=0x90;
SPBRG=0x9b;
}
void enter(void)//ACSII Keycode for "Enter"
{
while(!TRMT);
TXREG=0x0d;
}
void tx_start(void)//ASCII Keycode for "Ctrl+Z"
{
while(!TRMT);
TXREG=0x1a;
}
void send_msg(const char*str)//Sending String of Characters
{
char ps;
ps=*str;
while(ps>0)
{
str++;
if(ps==0)break;
while(!TRMT);
TXREG=ps;
ps=*str;
}
}
void main(void)
{
init();
initUSART();
while(1)
{
if(RB1=1)
{
RB2=1;
RB3=1;
send_msg("at+cmgf=1");
enter();
__delay_ms(50);
send_msg("at+cmgs=");
send_msg("+6583010050");
enter();
__delay_ms(50);
send_msg("hello");
tx_start();
__delay_ms(50);
RB2=0;
RB3=0;
}
else if(RB1=0)
{
RB2=0;
RB3=0;
}
}
}
3.这是我从网上找的USB的定义程序。。貌似有用。。。
#define TRUE 1
#define FALSE 0
#define NULL 0
#define NUM_CONFIGURATIONS 1
#define NUM_INTERFACES 1
#define ConfiguredUSB() while ((USWSTAT&0x3)!=CONFIG_STATE) {}
#define STALL_EP0 EP_STALL0 = 1
#define Send_0Len_pkt BD0IBC = 0; BD0IST = 0xc8; USB_dev_req = NULL
static volatile unsigned char bank3 USW_STAT @ 0x197;
#define POWERED_STATE 0x00
#define DEFAULT_STATE 0x01
#define ADDRESS_STATE 0x02
#define CONFIG_STATE 0x03
#define ENDPT_DISABLED 0x00
#define ENDPT_IN_ONLY 0x01
#define ENDPT_OUT_ONLY 0x02
#define ENDPT_CONTROL 0x06 /* enable for in, out and setup */
#define ENDPT_NON_CONTROL 0x0E /* enable for in, and out */
#define TOKEN_OUT (0x01<<2)
#define TOKEN_ACK (0x02<<2)
#define TOKEN_IN (0x09<<2)
#define TOKEN_SETUP (0x0D<<2)
#define CLEAR_FEATURE 0x01
#define GET_CONFIGURATION 0x08
#define GET_DESCRIPTOR 0x06
#define GET_INTERFACE 0x0A
#define GET_STATUS 0x00
#define SET_ADDRESS 0x05
#define SET_CONFIGURATION 0x09
#define SET_FEATURE 0x03
#define SET_INTERFACE 0x0B
#define HID_SET_REPORT 0x21
#define HID_GET_REPORT 0xA1
#define VEND_SET_MEMORY 0x80
#define HOSTTODEVICE 0x00
#define HOSTTOINTERFACE 0x01
#define HOSTTOENDPOINT 0x02
#define DEVICETOHOST 0x80
#define INTERFACETOHOST 0x81
#define ENDPOINTTOHOST 0x82
#define EP0OUT 0
#define EP0IN 1
#define EP1OUT 2
#define EP1IN 3
#define EP2OUT 4
#define EP2IN 5
// Descriptor Types
#define DEVICE 1
#define CONFIGURATION 2
#define STRING 3
#define INTERFACE 4
#define ENDPOINT 5
现在这是我所有能做得了 其他的已经不知道如何下手了 讲电路板上的USB插口连到电脑之后 最后要的结果就是在GUI的控制下 能够给手机发短信。。
小女子再次跪求。。而且今天是我的生日 但我实在被这个东西烦得不行了。。所以终于找到了这个论坛寻求帮助！！！
再次感谢！在线等！！
