Hi,
I have 24-bit RGB LCD interface with OMAP-L138 board, Which is interfaced with Parallel DE mode RGB input timing Values:
Parameter Symbol Min. Typ. Max. Unit
CLK frequency fclk 7 9 12 MHz
DEV period time Tv 277 288 400 H
DEV display area Tvd 272 H
DEV blanking Tvb 5 16 128 H
DEH period time Th 520 525 800 CLK
DEH display area Thd 480 CLK
DEH blanking Thb 40 45 320 CLK
CLK cycle time Tclk 83 110 200 ns
Clock width of high level Tcwh 40 50 60 %
Clock width of low level Tcwl 40 50 60 %
Clock rising time trck - 9 ns
Clock falling time tfck - 9 ns
Data Setup Time tdesu 10 - - ns
Data Hold Time tdahd 10 - - ns
DE Setup Time tdesu 10 - - ns
DE Hold Time tdehd 10 - - ns
da8xx_panel timing
[1] = {
.name = "LCD00000",
.width = 480,
.height = 272,
.hfp = ???,
.hbp = ???,
.hsw = ???,
.vfp = ???,
.vbp = ???,
.vsw = ???,
.pxl_clk = ????,
.invert_pxl_clk = ??,
},
Can i have the timing parameters setting in linux driver. How to control using with DE signal. Please give me a driver modifications.
Thanks
