Hi all,
Now I have made a project of Camera-Projection with i.MX6 quad, it can display now.
However when display the real-time image from the camera, the early image will not clear until ~30 seconds,like following:
1.I put a paper under the camera
2. When I move the paper, the image is still display
My projector parameters are as following:
QVGA
Description Min Type Max Unit
Horizontal total 344 400 488 Pixel
Horizontal active - 320 - Pixel
Horizontal blank - 80 - Pixel
Vertical total 251 300 2000 line
Vertical active - 240 - line
Vertical blank - 60 - line
My linux driver is:
/* 320x240 @ 120 Hz , pixel clk @ 14.4MHz */
const char *name; "My_projector",
u32 refresh; 120,
u32 xres; 320,
u32 yres; 240,
u32 pixclock; 69444,
u32 left_margin; 20,
u32 right_margin; 59,
u32 upper_margin; 20,
u32 lower_margin; 39,
u32 hsync_len; 1,
u32 vsync_len; 1,
u32 sync; 0,
u32 vmode; FB_VMODE_NONINTERLACED,
u32 flag; 0,
What's the problem? What should I do?
Hi, jamesbone.Thanks for your reply!
But we have signed a confidentiality agreement with the company, so I can only give you part of the datasheet.
This projector only support DE mode, and the datasheet doesn't have the front and back porch, all specification is as following(the picture is cut from the datasheet, not scaled):
QVGA
Description Min Type Max Unit
Horizontal total 344 400 488 Pixel
Horizontal active - 320 - Pixel
Horizontal blank - 80 - Pixel
Vertical total 251 300 2000 line
Vertical active - 240 - line
Vertical blank - 60 - line
Frame Rate - 120 - Hz
Pixel clock - 14.4M - Hz
The parameters from top to bottom are : VSYN, HSYN, (The parameter on original datasheet is not clear too,I can't recognize it),DE, CLK, R[5:0], G[5:0], B[5:0]
