I too, am trying to connect
an LCD to the DC5 (& DC4) connector in RGB888 mode. But, I cannot get the
VCLK, VSYNC nor HSYNC to toggle. I think I have followed all of the advice
given. Could someone please dump the OSD and VENC register sets and email a
copy to me? Thanks, Tony ---------------------------------------------------------------------- Message: 1 Date: Wed, 27 Sep 2006

could happen if you are using RGB666 mode. RGB666 mode is not working.
Use instead a LCD888 mode and don't connect 2 LSB singals for each color
component. > Maybe the DCLK is not

registers are not docummented. The following configuration
works for me: 0x0800 value for DCLKCTL 0x0001 value for DCLKPTN0 > 4. Anything related
that may help. There is a lot of registers
to setup. Wojciech gave me this advice: "Make sure that you set
proper polarization on sync signals. After that please verify the
manual of the LCD and set proper timings for H&V synsc. Then you have to
set the VPBE clock correctly. Next thing is to synchronize VPBE clock with OSD
clock ans set proper phases and dyty cycle. After that everytings should
work." Regards, Carlos |
