Our use case is as follows:
Input:
525p/60Hz YPrPb
Output:
YCbCr 8Bit 422 HS/VS
VS pin and DE pin are used. (SAV/EAV is not used.)
script configure:
##CP 525p/625p##
:525p/60Hz YPrPb In 8Bit 422 HS/VS Encoder:
42 05 01 ; PRIM_MODE = 001b COMP
42 06 06 ; VID_STD for 525P 2x1
42 C3 56 ; ADC1 to Ain8, ADC0 to Ain10,
42 C4 B4 ; Enables manual override of mux & ADC2 to Ain6.
42 1D 47 ; Enable 28.63636MHz crystal

Question 1
520P YPbPr input no work OK( no video image disaplay) blue screen bug, help us check?
Question 2
Y ---- ADC0 Pb --- ADC1 Pr --- ADC2 right? configure other (e.g. Y--ADC3 Pb--ADC2) ?
Question 3
1) remove horizontal blank, only have active data(720x2=1440), similar CMOS sensor output(HREF pin) timing ? from pin DE mode
2) remove vertical blank line, only have active line (480 line), similar CMOS sensor output(VSYNC pin) timing ? from pin VS
our post need timing :
Regards,
