DLPDLCR3010EVM: Need help writing batch file for max led current, content-adaptive illumination and color temperature.

Hi Manuel, 

It is a two step process, 

Step1: Create a list of I2C commands which you would like to apply on system startup, for example, set maximum brightness for this you have add command to set LED currents which is defined in section 4.1.3.33 Write RGB LED Current (54h), and similarly for the CAIC setting register. Once you have created list of registers with settings,  goto the next step.

Step2: Refer to this thread discussion where it explains setting some other settings on startup http://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/video_and_data_display/f/993/p/573356/2105607

Hi Sanjeev,

I understand what you are saying, but as I stated before, I do not know how to write the I2C commands. I have read the 4.1.3.33 Write RGB LED Current section in the Programmer's Guide, but I still do not understand it. Can you give me an example code that I could work with?

Refer to EVM user's guide http://www.ti.com/lit/ug/dlpu021a/dlpu021a.pdf Section 4.7 Advanced Mode

Regards,
Sanjeev

So can you verify if my I2C commands are correct:

####### Set up Look Select #######

## Write: Look Select = 2 (Warm Color Temperature)
W 36 22 02

# 100 ms delay
W 36 DB 64 00

####### Set up Illumination #######

## Write: RGB LED Current
W 36 54 ff 03 ff 03 ff 03

## Write: RGB LED Max Current
W 36 5c ff 03 ff 03 ff 03

# 100 ms delay
W 36 DB 64 00

######## Set up Image #######

## Write: CAIC Local Area Brightness Control
W 36 80 b1 00

## Write: CAIC Image Processing Control
W 36 84 00 80 00

# 100 ms delay
W 36 DB 64 00

-------------------------------------------------------------------------------------

Note: I tried to add this file into the "Auto-Init Update" section, but when I click "Update Flash" I get the following error: "Error: File is not a valid image." Can you tell me what may be the issue? All I did was write the commands in Notepad and changed the extension to ".bf" Was that the wrong way to do it?

While saving from notepad you can do the following, saveas and give the filename and extension in double quotes like "autoinit.bf" then save.

Reagrds,
Sanjeev

I did do that, but it is still giving me the same error.

Since the Auto-Init Update has 3 Batch File Options, am I suppose to be uploading another batch file in addition to the one I created? Because I see the note, "One of the user defined batch files must set-up start-up source," does that also mean I am suppose to add something to my created batch file?

How about you add these commands to existing autoinit batchfile and try.

Where can I locate the existing autoinit batch file?

I believe I found the autoinit batch file. This is the code in it:

Even after I tried: 1) Running the batch file separately, 2) Running the batch file and my custom batch file & 3) Putting my custom I2C code into the autoinit batch file, I still received the same error in each scenario.
