Hi ,

Could you help generate a dsi84 test pattern register setting?

LVDS:

1920 x 1080

dual lvds

24bpp

dsi blank:

hfp 64 vfp 70

hbp 32 vbp 8

hpw 32 vpw 8

Single lvds clk 71.6M

de polarity: positive，hs vs polarity: negative

lvds channel : Format2

clock reference: csi

best regards,

You can use the attached DSI Tuner to generate the DSI84 register programming value.

Hi,

You can download the Java environment from this link, http://javadl.oracle.com/webapps/download/AutoDL?BundleId=44457.

I generated the DSI84 programming value assume RGB888 and DSI CLK frequency of 429.6MHz with divider of 6. I would recommend using the reference clock instead the DSI clock since the reference clock tends to have cleaner jitter than the DSI clock.

The PLL_EN bit and SOFT_RESET bit are not set as they need to be set per the recommended sequence defined in the datasheet

Thanks
