Hi
We are designed new uclinux based board.
we are using only 8-bit data connection between adv7393 and PPI(Upper 8-bit).we are provideing 27MHz clock input to adv7393 encoder.
So i need to change the driver for 8bit data trasfer.
First i am checking the test pattern.
The code is here:
static const u8 init_NTSC_TESTPATTERN[] = {
0x00, 0x1C, /*Power up all DACs. PLL off */
0x02, 0x20, /*Composite output (CVBS), color bar */
0x82, 0xCB, /*Step control on, pixel data valid, pedestal on, PrPb SSAF on, CVBS/YC output.*/
0x84, 0xC0, /* CBVS Color Bar Test Pattern Enabled, DAC 2 = Luma, DAC 3 = Chroma */
};
static const u8 init_NTSC_TESTPATTERN_BLACK[] = {
0x00, 0x1C, /*Power up all DACs. PLL off */
0x02, 0x24, /*Composite output (CVBS), black bar */
0x82, 0xCB, /*Step control on, pixel data valid, pedestal on, PrPb SSAF on, CVBS/YC output.*/
0x84, 0x40, /*SD Color Bar Test Pattern Enabled, DAC 2 = Luma, DAC 3 = Chroma */
};
What would be the output.
I am connecting DAC1 output into TV.
I am geeting some some DOT color output in TV.
I am not sure is it correct output.
Help me in this issue.
