Hi guys,
I am using the demo code of D5M on DE2-115. And I didn't change the camera settings in I2C_CCD_Config, in which Width = 800, HBMIN(horizontal blank) = 500, PIXLCLK = 50MHz.
So the length of Line_VALID signal should be 800 + 500*2 = 1800, correct?
But when I monitored the signal of Line_VALID，I found that:
time Line_VALID = 1 is 16 us, which equals 800 pixels. This is meaningful
but time Line_VALID = 0 is about 31.1 us, which equals around 1555. But I though it should be 2*HBMIN = 1000.
Can you tell me which part is wrong? Thanks very much!
BTW: The default settings for D5M camera are:
EXTCLK (MHz) 50
Col_Bin 1
Row_Bin 1
Col_Skip 1
Row_Skip 1
Col_Size 1599
Row_Size 1199
Shutter Width (SW) 1984
Horizontal Blanking 0
Vertical Blanking 25
