Other Parts Discussed in Thread: OMAP3530
Hi,
I am new to OMAP.
I made a custom board for omap3530, & using MISTRAL EVM BSP (modified).
THe LCD display is interfaced through a LVDS converter. the problem is that the LCD doesnt accept HSYNC & VSYNC. as per its datasheet it manages everything through DataEnable. the timing diagram is included in attachments. can any one suggest the
#define LCD_HSW
#define LCD_HFP
#define LCD_HBP
#define LCD_VSW
#define LCD_VFP
#define LCD_VBP
values..??
the horizontal blanking period is mentioned as 20 to 256, but max value for HSW is 63: so instead of HSW can we assign values to HFP & HBP..??
but as per datasheet no HFP and HBP values are mentioned.
If I use these values
#define LCD_HSW 63
#define LCD_HFP 137
#define LCD_HBP 0
#define LCD_VSW 2
#define LCD_VFP 0
#define LCD_VBP 0
we are getting a image ofset in horizontal direction by 200 pixels, but if I try to reduce LCD_HSW, LCD_HFP values it doesn't display at all.
can any one suggest where can be the problem.?
Thanks in Advance,
Sandeep A
