The Trizeps6 can show a splash-screen during device start. The Windows CE OS-image can then take the display-parameters from this splash-screen. This allows an easy change of the display, without the need to modify the Windows CE OS-image.

See BitmapBoot Tool ( Trizeps II - V) if you want to show a BootBitmap on Trizeps2,3,4 or 5.

On Trizeps6 you need to create two files:

  • The bitmap to be shown.

  • A script that includes the display-settings.

Simply create a bitmap with your favorite paint-program. It must have 8Bpp color-depth ( in Windows Paint choose to save as 256 color bitmap)

This picture should be the same resolution as the display. If not, it is automatically stretched to fit the display-size.

Display-Script

The Trizeps6 got a boot-partition from which it can load files and scripts. The display-script can be put into autoboot.bat or a script, which is referenced by autoboot.bat.

Example of a display-script for the ConXS-Evaluation board:

640        CxScreen !
480        CyScreen !
0x8000001b ClockDivider !
0x2        HBackPorch !
0x35       HFrontPorch !
0x19       HSyncWidth !
0x1        VBackPorch !
0x2        VFrontPorch !
0x1        VSyncWidth !
0xc        SyncPolarity !
0x2        BufferStrength !
display
boot nanddisk wince.bmp
0x10 0xbb7a0000 !16
0x10 0xbb700000 !16

The parameter names are the same as in the registry ( Display Parameters).
With the bootloader-command display, the display-controller is initialized with the current settings. boot nanddisk wince.bmp loads a picture with the name wince.bmp into the current framebuffer. The last two lines are specific to the ConXS and enable the backlight. When using a Trizeps6 without WLAN/Bluetooth, replace the last two lines with:

0x10 0xbd700000 !16

See Trizeps6 CPLD for details.

Store Boot Script and Picture

The script can be run from SD-card. The boot-picture may also reside there.
If you want to store it to the internal boot-partition follow these steps:

  1. Create a autoboot.bat ( see Display-Script).

  2. Create a boot-picture ( i.e. wince.bmp).

  3. Store both files on a SD-Card.

  4. Plug SD-Card and enter bootloader:

  5. Remove previous boot-script and picture ( i.e. with del autoboot.bat and del wince.bmp)

  6. Run store mmc autoboot.bat autoboot.bat

  7. Run store mmc wince.bmp wince.bmp

Note that the filenames should not be longer than 8 characters and do not begin with a number!!
