Cannot shake hands LPC1768 and C1098-SS

I am using LPC1768 and C1098-SS(http://silentsystem.jp/c1098.htm,http://www.silentsystem.jp/download/C1098UM.pdf). Now the mbed send　initialization signal and try to shake hands the mbed and the camera. But shake hands command is not unsuccessful. Mbed often catch a signal from C1098 or not. And the signal doesn't have no meaning. Why? I didn't understand...

<main.h> #include "mbed.h" #include "CameraC1098.h"

  1. CameraC1098 camera(p9, p10);
  2. int main()
  3. {
  4. printf("\r\n");
  5. printf("==========\r\n");
  6. printf("CameraC1098\r\n");
  7. printf("==========\r\n");
  8. CameraC1098::ErrorNumber err = CameraC1098::NoError;
  9. err = camera.init(CameraC1098::Baud14400, CameraC1098::JpegResolution320x240); 460800 change 14400
  10. if (CameraC1098::NoError == err)
  11. {printf("[ OK ] : CameraC1098::init\r\n");}
  12. else
  13. {printf("[FAIL] : CameraC1098::init (Error=%02X)\r\n", (int)err);}
  14. return 0;
  15. }

<cameraC1098.h> http://mbed.org/users/sunifu/code/CameraC1098/file/5a6468b4164d/CameraC1098.h

<cameraC1098.cpp> http://mbed.org/users/sunifu/code/CameraC1098/file/5a6468b4164d/CameraC1098.cpp

And add the code for check what Mbed is working.
413Line printf("RECVFUNC(recv, sizeof(recv)):%02x\r\n",RECVFUNC(recv, sizeof(recv)));return 00,Mbed cannot receive signals from camera, return 01, Mbed catch it.
471Line printf("i:%d buf[i]:%02x\r\n",i,buf[i]); buf[i] is the data from C1098

Hi Lab1 MIYAZAKI san. I am Sorry. I did not notice a question. It is a cause that designation of the transmission baudrate of mbed is not considered to be. Please test it with this program.

Sample

#include "mbed.h"
#include "CameraC1098.h"
CameraC1098 camera(p9, p10); 

int main()
{
    printf("\r\n"); 
    printf("==========\r\n"); 
    printf("CameraC1098\r\n"); 
    printf("==========\r\n"); 
    camera.setmbedBaud(CameraC1098::Baud14400); // <= this!
    CameraC1098::ErrorNumber err = CameraC1098::NoError; 
    err = camera.init(CameraC1098::Baud14400, CameraC1098::JpegResolution320x240); 
    if (CameraC1098::NoError == err) 
    {
        printf("[ OK ] : CameraC1098::init\r\n");
    } 
    else 
    {
        printf("[FAIL] : CameraC1098::init (Error=%02X)\r\n", (int)err);
    } 
    return 0; 
}
