wd Reset

[Lucho1976]

HI Guys when i set a resolution above 320x240 i get an wd reset arduino. Dou you know why?.

I have an OV2640 2 MP and running the V2_capture2sd example.

I get this error:

SD Card detected!
OV2640 detected.
Star Capture
Capture Done.
The fifo length is :67588

Soft WDT reset

Hi,
Please try add some 'yield() ' in the code.

Regards.

[Lucho1976]

I already did it on myCAMSaveToSDFile function.
it already worked fine but i format my computer, reinstall arduino and arducam and now does not work, may be different version. Now i have 2.2.2

Is this ok the place where i add the yield(), is this ok ?
Thanks a lot.

//Read JPEG data from FIFO
if ( (temp == 0xD9) && (temp_last == 0xFF) ) //If find the end ,break while,
{
buf[i++] = temp; //save the last 0XD9
//Write the remain bytes in the buffer
myCAM.CS_HIGH();
outFile.write(buf, i);
yield() ; //*****HERE
yield() ; //*****HERE
//Close the file
outFile.close();
Serial.println(F("Image save OK."));
is_header = false;
i = 0;
}
if (is_header == true)
{
//Write image data to buffer if not full
if (i < 256)
buf[i++] = temp;
else
{
//Write 256 bytes image data to file
myCAM.CS_HIGH();
outFile.write(buf, 256);
yield() ; //*****HERE
yield() ; //*****HERE
i = 0;
buf[i++] = temp;
myCAM.CS_LOW();
myCAM.set_fifo_burst();
}
}

Hi,
You can try add yield like the below code.
We suggest you check your hardware connection firstly.
Maybe your hardware exist some bad connections.
buf[i++] = temp; //save the last 0XD9
yield() ; //*****HERE
yield() ; //*****HERE
//Write the remain bytes in the buffer
myCAM.CS_HIGH();
outFile.write(buf, i);

//Close the file
outFile.close();
Serial.println(F("Image save OK."));
is_header = false;
i = 0;
}
if (is_header == true)
{
//Write image data to buffer if not full
if (i < 256)
buf[i++] = temp;
yield() ; //*****HERE
yield() ; //*****HERE
else
{
//Write 256 bytes image data to file
myCAM.CS_HIGH();
outFile.write(buf, 256);

Hi Guys it work fine with 800x600 resolution but above that same problem. I added some more yield but the same thing.

I have an arducam V2 and a OV2640 ( REV. B) 2MP

I tried with memorysaver.h in this two configuracion and compile the whole project but wich one is the correct? :

A)

//Step 1: select the hardware platform, only one at a time
//#define OV2640_MINI_2MP
//#define OV5642_MINI_5MP
//#define OV5642_MINI_5MP_BIT_ROTATION_FIXED
//#define OV5642_MINI_5MP_PLUS
//#define OV5640_MINI_5MP_PLUS

//#define ARDUCAM_SHIELD_REVC
#define ARDUCAM_SHIELD_V2

//Step 2: Select one of the camera module, only one at a time
#if (defined(ARDUCAM_SHIELD_REVC) || defined(ARDUCAM_SHIELD_V2))
//#define OV7660_CAM
//#define OV7725_CAM
//#define OV7670_CAM
//#define OV7675_CAM
#define OV2640_CAM
//#define OV3640_CAM
//#define OV5642_CAM
//#define OV5640_CAM

//#define MT9D111A_CAM
//#define MT9D111B_CAM
//#define MT9M112_CAM
//#define MT9V111_CAM	
//#define MT9M001_CAM	
//#define MT9T112_CAM
//#define MT9D112_CAM

#endif

B)

//Step 1: select the hardware platform, only one at a time
#define OV2640_MINI_2MP
//#define OV5642_MINI_5MP
//#define OV5642_MINI_5MP_BIT_ROTATION_FIXED
//#define OV5642_MINI_5MP_PLUS
//#define OV5640_MINI_5MP_PLUS

//#define ARDUCAM_SHIELD_REVC
//#define ARDUCAM_SHIELD_V2

//#define MT9T112_CAM
//#define MT9D112_CAM

#endif

if you think i can try another thing or add some other yield in other section of the function i will appreciate so much.

Now is working with configure A) in OV2640_1280x1024 and it's fine to me.

Thank you guys

[Lucho1976]

Again i got WDT reset, i add some serial.println and it fails just in this lines:

outFile.write(buf, 256);

i added 2, 4, 8 yield() but the same problem. i tried with A) and B) memorysaver.h above described but the same thing.

When i use the /capture demo i can visualize perfectly the image but i can't write to SD card.
Also connected the camara direct to the board ( no duppont wires )

The sd CARD is in FAT32, is that right ?

Can you help me?...

thank

@Lucho1976
Hi,
yes, you can use the SDFormatter software to format
your SD card firstly.

Let us know if you need more help.
