My project structure is VIDEO -> ADV7182A -> FPGA -> PC. I got EVAL-ADV7182AEBZ evaluation board and i used it to show video on montitor
Now i want to use only ADV7182A because i just need 8 pixel port and LLC clock.
I have configured ADV7182A to use FPGA over the I2Cprotocol according to this
##02_CVBS SINGLE ENDED AUTODETECT ##
:Autodetect CVBS Single Ended In Ain 1, YPbPr Out:
delay 10 ; Wait 10ms After Hardware Reset To Start I2C
42 0F 80 ; Reset ADV7182
delay 10 ; Wait 10ms
42 0F 00 ; Exit Power Down Mode [ADV7182A writes begin]
42 52 CD ; SE_CVBS AFE IBIAS
42 00 00 ; CVBS in on AIN1
42 0E 80 ; ADI Required Write
42 9C 00 ; Reset Current Clamp Circuitry [step1]
42 9C FF ; Reset Current Clamp Circuitry [step2]
42 0E 00 ; Enter User Sub Map
42 17 41 ; Enable SH1
42 03 0C ; Enable Pixel & Sync output drivers
42 04 07 ; Power-up INTRQ, HS & VS pads
42 13 00 ; Enable ADV7182A for 28_63636MHz crystal
42 1D 40 ; Enable LLC output driver [ADV7182A writes finished]
I have a problem that the image is not displayed as expected.(I got 27Mhz LLC clock and 28.63636 Mhz Crystal)
The picture below is not showing as expected. Rather, it doesn't show that many vertical black stripes.
Has anyone seen this problem??
