Hi,
I'm trying to take video images live from a panasonic video camera which works on Pal format. The problem is that the images are doubled when they are put in the Blackfin memory and I want to put them corectly in DMA.I believe I have to modify the adi_adv7183.c file when before the image is put in memory (more exactly when I read each frame through PPI) , I think somewhere here. When I want to see the picture with Image viewer in Visual Dsp the only width and height in pixels are 864/625 on which the picture is of a good quality.
if(u32Value == NTSC_FORMAT)
{
pADV7183->ADV7183Ppi.ppiF_Lines = 525; // NTSC mode
#if defined (__ADSP_MOAB__)
pADV7183->ADV7183Ppi.PpiSamplesPerLine = 1716;
#endif
}
else
{
pADV7183->ADV7183Ppi.ppiF_Lines = 625; // PAL mode
#if defined (__ADSP_MOAB__)
pADV7183->ADV7183Ppi.PpiSamplesPerLine = 1728;
#endif
}
#if defined (__ADSP_EDINBURGH__) || defined (__ADSP_BRAEMAR__) || defined (__ADSP_STIRLING__) || defined (__ADSP_TETON__)
Result = adi_dev_Control(pADV7183->ADV7183Ppi.ppiHandle, ADI_PPI_CMD_SET_LINES_PER_FRAME_REG,(void *)pADV7183->ADV7183Ppi.ppiF_Lines);
#elif defined (__ADSP_MOAB__)
Result = adi_dev_Control(pADV7183->ADV7183Ppi.ppiHandle, ADI_EPPI_CMD_SET_SAMPLES_PER_LINE,(void *)pADV7183->ADV7183Ppi.PpiSamplesPerLine);
I attached the project and an example of a distorted picture . Pleaseeeee give me idea !
