DS90UB954-Q1: How to set PGEN_COLORx registers to get at least 3 color bar in RGB by RAW12 format ?

Hi Keelung, 

I would recommend that you use our PATGEN tab in our ALP GUI. You can configure the number of color bars (1, 2, 4, or 8). and the colors can be modified in registers PGEN_COLORX.

I know you can generate solid Blue pattern by setting registers 0x10 = 0xff while setting 0x11 and 0x12 = 0x00. You can get a solid Green by setting 0x11 = 0xff and 0x10 and 0x12 = 0x00. You can get a solid Red by setting 0x12 = 0xff and 0x10, 0x11 =0x00. So you may have to play around a little with how you offset the colors to get the right RGB bars.

Thanks,

Hi Sally,

Even use PATGEN in ALP GUI, then how to display? You still need one of vision apps which set ser/des registers again.

So I don't think using PATGEN ALP GUI is a good idea.

I tested your solution in multi-cam app by selected UB9xxx_RAW12_TESTPATTERN sensor / LDC(No) / 1 camera enabled.

After removing DCC in ISS_SENSOR_RAWTESTPAT_FEATURES in imaging/sensor_drv/src/ub9xx_raw_test_pattern/iss_sensor_raw_testpat.h,

and fixing AWE issues as descripted in https://e2e.ti.com/support/processors/f/791/t/976128, 

I still get wrong colors which not as the same as you descripted.

Here are my settings and display results:

0. Change RAWTESTPAT_DES_CFG_SIZE from 39 to 45 in  imaging/sensor_drv/src/ub9xx_raw_test_pattern/raw_testpat_serdes_config.h

1. Set [0x10, 0x11, 0x12] registers to [00, FF, 00], and got display:

2. Set [0x10, 0x11, 0x12] registers to [00, 00, FF], and got display:

And BTW, if DCC enabled, then the display is very dark, but the colors are still as same as when DCC disabled.

Finally, all what I wanted is displaying at least 3 bars in Red, Green, and Blue on my monitor by setting PGEN_COLORx

Hi Keelung, 

We have a patgen tab and you progam your parameters. From there, then you can hit apply and display registers. You can copy those registers into your script.

See my image example.

Hi Sally,

Please check the thread title, the question at the end of the first post, the sensor driver I selected, the changing of registers, and the related thread.

All of them are talking about RAW12, not RGB888.

Hi Keelung, 

I understand that your data type is raw 12. I was just showing you the default view, so you can change it in PATGEN. 

Thanks

Hi Sally,

You bring me to another way. My question is about RAW12 not RGB888. And in your first answer you even not metioned your format is RGB888.

You can not just change PGEN_COLORx or PGEN_CSI_DI to got the right result. They must be changed at same time, and also other registers such as PGEN_LINE_SIZE.

Can you shown your register settings which can show 3 bars in red/green/blue by RAW12 format?

I can't. That why I create this thread here.

Thanks!

Hi Keelung, 

Please give me all your video parameters and I can send you the script. 

fps? (e.g. 30 fps)

horizontal active timing ? (e.g. 1920)

vertical active timing? (e.g. 1080)

vertical blanking timing? (e.g. 200)

Thanks

Hi Sally,

Here are my sensor's parameters which snapshoted from datasheet. 

And FPS == 30 is a safe value for testing.

Thanks!!

Hi Casey,

Thanks for your info!

But color bar no color doesn't make sense for many newbies of Ti Ser/Des.

I don't understand why inverse pattern is enabled forcely, and users can not disable it.

Anyway, users should be allowed to generate any color in PATGEN in supported pixel formats.

Limited pattern isn't a good design.
