Other Parts Discussed in Thread: TM4C123GH6PGE

Hi,

Im Srinivas, Im using CORTEX-M4 TM4C123GH6PGE. For this i need to implement inserting bootable image(company logo). This will load at the time of power on condition (load from EEPROM), after that our actual menu has to be displayed. In Tivaware-grlib, have the example code for inserting image(ex. ti logo). For this image, code is in the form of hexadecimal, So how can i convert image into hex format. This image will display in OLED.

OR

is there any other solutions for this implementation.

Hi,

Search your Tiva installation for pnmtoc.exe application. Also, in docs/release notes, how to use it.

Hi,

You may find it in <TivaWare_installation>/tools/bin/ folder (source code available in /tools/pnmtoc/folder).

yes , i was run from the command prompt.

i changed the directory like below

1) cd C:\ti\TivaWare_C_Series-2.1.0.12573\tools\bin

i converted the image type to pnm format. kept in the above path only.

then

pnmtoc -c filename.pnm

then hex code has been generated.

thanking you every one.....................
