DLPC6540: DLP471TPEVM warping control

Hello User,

Beside the information above, please also refer to the DLPC6540 Programmer's Guide Section 19.13 for more Warping information.

Thank you for your answer.

I also know the GUI tool - advanced - Warping menu.

But there are two types of distortion as below.
There are "pincusion" and "barrel" types. How should I apply each of them?

Can you give me an example of how to do this?

Hello Ted,

Please let me check if we have examples that can be provided to you. I'll get back to you by the end of this week.

Lori 

Hello Ted,

You will need to evaluate/test the warping feature by following the software programmer's guide to create the warping distortion yourself. Unfortunately, we don't have a demo for now.

Hello Lori,

I created a test script file as below and did a warping test.

However, there is no change on screen.

Please check the log message that ran the script file as below.

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

1. script code

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

Summary = WriteManualWarpTableUpdateMode (0)

if Summary.Successful:
print("[Warping] Write Manual WarpTable Update")
else:
print("[Warping] Failed to Write Manual WarpTable Update")

ControlPointsDefinedByArray = 0
HorizontalCtrlPoints = [4]
VerticalCtrlPoints = [3]
Summary = WriteManualWarpControlPoints ( ControlPointsDefinedByArray, HorizontalCtrlPoints, VerticalCtrlPoints )
if Summary.Successful:
print("[Warping] Write Manual Control Points")
else:
print("[Warping] Failed to Write Manual Control Points")

Summary, ControlPointsDefinedByArray, CtrlPoints = ReadManualWarpControlPoints ( )
if Summary.Successful:
print("[Warping] ControlPointsDefinedByArray = %d" %ControlPointsDefinedByArray)
print(CtrlPoints)
else:
print("[Warping] Failed to Read Manual WarpControlPoints")

Summary = WriteApplyManualWarping(True)
if Summary.Successful:
print("[Warping] Write Apply Manual Warping")
else:
print("[Warping] Failed to Write Apply Manual Warping")

Hello Ted,

Are you able to manually write these warping commands through GUI? 

When you figure out what warping commands you want, you can use GUI -> Debug -> Command Log to see the commands and order, then you should be able to implement them into a script.

Hello Lori,

Can you help me a method or example of how to manually write these warping commands via the GUI?

I'm not sure how to use (operation sequence) the GUI to control warping.

Hello Ted,

I'll need to test an example on the EVM and provide you information by the end of this week.

Hello, Lori

I have a another question.
I am testing the keystone operation from an external MCU to the DLP471TP EVM Kit.
I connected the I2C line of the MCU to the I2C0 port (J16 connector) of the EV Kit.
Is the I2C port 0 (slave mode) among the I2C ports of the DLPC6540 that can be controlled by the external MCU?
And is the default slave address 0x34 (8bit)?

When I read the 13 bytes of Table 19-5. Controller Info [Opcode: 00h],  it is read as follows.

--- i2c read : 00h ------------------------------------
80 00 00 00 00 00 00 00 00 00 00 00
--------------------------------------------------------

I am Tested i2c clock 400KHz, 100KHz on MCU

------ i2c read cde ----------------------------------
i2c_read(0x00, buf, 13);
----------------------------------------------------------

Do I need to set up something on DLPC6540 if I want to control it with i2c from an external MCU?

Regards,

Ted.

Hello Ted,

I'll need to look into this later this week and get back to you by end of next week.
