Can I modify the boot splash image of ControlX?

[hikari_calyx]

Recently I installed ControlX on my Nspire CX CAS (HW: L).
It works well, but I feel the splash image is really ugly

Update: Yes it's possible to modify ControlX splash
Here's the modified ctrlx tns, modified s_screen.c and the result:

Hi.


Unfortunately nBoot code does overwrite the TI-Nspire boot splash in the Manuf partition.
So it's not possible to use it.

The replacement boot splash used by ControlX is in the s_screen.c file.
It's rgb565 with a width of 320px.

I tried to use Image2Lcd and I got this (partial):

Code: Select all

const unsigned char gImage_123_splash[86400] = { /* 0X00,0X10,0XF0,0X00,0XB4,0X00,0X01,0X1B, */
0X77,0X84,0X77,0X84,0X77,0X8C,0X35,0X7C,0X77,0X8C,0XB4,0X73,0XAB,0X31,0X73,0X63,
...
0XD4,0X73,0XD4,0X73,0XD4,0X73,0XD4,0X73,0XD4,0X73,0XD4,0X73,0XB4,0X6B,0X93,0X6B,
};


It looks totally different from s_screen.c:

Code: Select all

char databuffer[]=
  "~\357}\357~\357\236\357\236\357\277\357\277\357\277\357\277"
  "\357\277\357\237\357\277\357\237\357\277\357\277\357\236\357\236\357\236"
  "\357\237\357\277\357\277\357\277\357\237\357\237\357\277\357\277\357\277"
  "\357\277\357\277\357\236\357~\357\236\357\237\357\277\357\277\357\277\357"
...
  "\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377"
  "\377\377\377\377\377\377\377\377"
;

Any idea to convert a picture into the format like s_screen.c?

Well, this is just another way of representing an array of bytes.

It should compile (I didn't say work - depends upon the content).

OK. Since it takes lots of time to build Ndless SDK on my backup PC and I can't compile it immediately.
Can you compile it for me? Modified s_screen.c and the 24-bit BMP splash are attached below.
Thank's a lot.

There is no real need to recompile what is essentially a raw data buffer. I'm fairly sure it would possible to just swap the image data in the .tns directly (it's probably towards the end of the file) - that's of course as long as it's the exact same size, but in this case it is.

Well, I asked my friend to compile. It did work, but the output looks glitchy.
Trying again now, maybe there's mistake when I was using Image2LCD.

Edit: Finally done.

Great - have fun !
