Hi,

The CLEAR_TAG is intended to set the value to which the tag buffer is initialised and so you can do this before your clear(1,1,1). For example, here we set the tag buffer to 255. When you touch your rectangle, you should get tag 151 and if you touch an untagged area then you should get tag 255. Alternatively, you can remove CLEAR_TAG and the CLEAR(1,1,1) will clear the tag buffer to default.
Also (if you will run your display list constantly in a loop to update items on the screen) you can load the image from flash just once so that it does not happen on each screen update

Gpu_CoCmd_FlashRead(phost, 4096, 4096, 261120);


Gpu_CoCmd_Dlstart(phost);
App_WrCoCmd_Buffer(phost, CLEAR_TAG(255));
App_WrCoCmd_Buffer(phost, CLEAR(1, 1, 1));
App_WrCoCmd_Buffer(phost, BEGIN(BITMAPS));
Gpu_CoCmd_SetBitmap(phost, 4096, ARGB1555, 480, 272);
App_WrCoCmd_Buffer(phost, COLOR_A(245));
App_WrCoCmd_Buffer(phost, VERTEX2II(0, 0, 0, 0));
App_WrCoCmd_Buffer(phost, TAG_MASK(1));
App_WrCoCmd_Buffer(phost, TAG(151));
App_WrCoCmd_Buffer(phost, BEGIN(RECTS));
App_WrCoCmd_Buffer(phost, VERTEX2F(400, 1040));
App_WrCoCmd_Buffer(phost, VERTEX2F(3616, 1344));
App_WrCoCmd_Buffer(phost, TAG_MASK(0));

Hi Florian,

This should work well but we can try it here,

Do you load all images on the same screen or are you displaying one at a time?
Also, are they large images or just small icons?

Do you have some images which we could try so that we use the same ones?
You can email them if preferred to support.emea@brtchip.com and we can try them,
Please also include details of which addresses you load them to and if possible a screenshot of your asset builder for Image conversion and for the Bin file creation so that we can try to recreate it as closely as possible.

p.s. If you don't use EAB for loading the data, ensure that your flash alignment meets all requirements for SetBitmap (works in 32 byte blocks) and for the flash commands if you write the data using Flashupdate etc. (4096 byte alignment)

Hi,

Here is an example showing one way to do it.

By using CMD_ROMFONT to assign the font 34 to handle 1, we can get the properties of the font using EVE Screen Editor etc. Using these properties, we can then do the rotation. The translate helps to avoid clipping.

Here is the code and please find an image showing the rotation attached.

CLEAR(1, 1, 1)
CMD_ROMFONT(1,34)  //Load the settings of built-in font 34 into bitmap handle 1

BITMAP_LAYOUT_H(0,0)
BITMAP_SIZE(NEAREST, BORDER,BORDER, 0,0) //Update the visible area of bitmap handle 1 to the maximum

CMD_LOADIDENTITY()
CMD_TRANSLATE(4128768, 3276800)
CMD_ROTATE(8192)
CMD_SETMATRIX()    //Configure transform matrix of bitmap

CMD_TEXT(77, 111, 1, 0, "TEST-ROTATED")  //Draw the text to be rotated

CMD_LOADIDENTITY()
CMD_SETMATRIX()    //Restore transform matrix of bitmap

CMD_ROMFONT(1,34)  //Re-load the setting of built-in font 34 into bitmap handle 1 to restore the visible area to normal
CMD_TEXT(100, 313, 1, 0, "TEST-Normal")  //Draw the normal text

Looks great!
Those EVE-powered displays look ideal for replacing the common monochrome LCD displays found on 19" rackmount devices (and many other systems too such as alarm panels) with full color touch-enabled screens. A great way to improve the appearance and functionality of existing products as well as new designs.

Hi,

We checked with our R&D team and they suggested a good solution using CMD_ROMFONT which works well, we will post the details of how to do it.

Hi,

Thanks for posting your new utility, that's a very useful tool to see how images look on the real screen, and to make sure that all of the hardware is set up correctly. The autodetect and scaling are really nice features too,

Hello Rudolph,

I see the same issue, thank you for reporting it to us!

I will inform our R&D team about it and get back to you with any updates soon.

Best regards

Hello,

We have some examples on this page below on our website:
