OMAPL138 StarterWare Raster LCD Example

Abdullah YILDIZ

Other Parts Discussed in Thread: OMAPL138, SYSBIOS, OMAP-L138

OMAPL138_StarterWare_1_10_03_03 is installed on my machine.

I used bmp2c utility to convert a BMP image to C file. When I build the project with the generated C header file, image is not displayed on LCD properly, i.e., a fuzzy image is shown repeatedly.

I used -16 option to convert it into 16-bit pixel values. I think the original image.h also stores 16-bit pixel values.

Could you help me with this?

Hi Abdullah,

The raster application is programmed to use an image of size 480 x 272 in case of OMAPL138.
There is no option in utility to resize the image to LCD size.
User is required to resize image to LCD size (480 x 272) before using bmp2c utility.

Please let me know if this answers your question.

Regards,
Vinay

Hi,

When you installed StarterWare for AM335x 720MHz ARM® processor, there should not be any issue about building the application.

You can install StarterWare for AM335x from:

Hi Abdullah,

Thanks for your reply,

One thing I forgot to mention in earlier post. I am trying to run this LCD application in SYSBIOS on BeagleBone.

I have installed "AM335X_StarterWare_02_00_00_07" staterware from the link which you have posted. But This starterware also doesn't have rasterdisplay.c for BeagleBone . I have compiled rasterdisplay.c present under evmAM335x folder for BeagleBone. But still i am not able to see any image on LCD.

Is this correct procedure what i am following?Please confirm on this.........

Thanks

Ram

Hi Ram,

I do not have any BeagleBone, but I think you are doing right.

Hi Abdullah!

I notice that, you were succeed with using bmp2c utility from StarterWare. Would you mind telling me how you did that? I read in ReadMe that I must have Framework installed on my PC, but I don't know what to do next, after installation. Could you help me with running the bmp2c? Thanks!

Hi Mat,

I used StarterWare on Windows OS for OMAP-L138. bmp2c utility is at the location

C:\ti\OMAPL138_StarterWare_1_10_04_01\tools\bmp2c

in my computer. When you run bmp2c.exe on the command line, you can easily figure it out.
