Hello,

 

i want to configure the internal Frame Sync generation for displaying PAL Video 720x576 with the commands:

 

adi_dev_Control(AD7179DriverHandle,ADI_ADV717x_CMD_SET_FRAME_SYNC_COUNT, (void*) ADI_ADV717x_FRAME_COUNT_2)

adi_dev_Control(AD7179DriverHandle,ADI_PPI_CMD_SET_TRANSFER_COUNT_REG, (void*) (1440 - 1)

adi_dev_Control(AD7179DriverHandle,ADI_ADV717x_CMD_SET_TIMER_FRAME_SYNC_1,(void*) &Hsync)

adi_dev_Control(AD7179DriverHandle,ADI_ADV717x_CMD_SET_TIMER_FRAME_SYNC_2,(void*) &Vsync)

 

Which values are correct for Hsync.width ,Hsync.period, Vsync.width, Vsync.period.

I could not find the timing data in the ADV717x datasheet.

 

Thank you

 

Robert
