Hello,

Unfortunately it is not possible to read the current context of the graphics engine via any API commands or registers.
As a note however the context stack only allows for 4 levels, and any subsequent restore will revert to the default graphics context.

Would you be able to provide an example of when a {CLEAR_}COLOR_RGB/A command does not work in your application?

Hello,

Thank you for the details.

I have managed to run the project and I am seeing the following co-processor error:

"invalid animation in cmd_animstart()"

Just to clarify is this the same error you are seeing?

I am currently in discussion with the ESD/EAB development team to asses what may be causing the behaviour you are seeing.

Hello,

The developers have asked if it is possible to provide the original PNG image files before any EAB conversion has taken place:
1.   PNG with transparent background.
2.   PNG with black background.

Also can you provide the display list utilised with the black background PNG and the setfont2 command?

Hello,

One alternative might be to make your own text function so that you can customise it.

We have an example in this application note draft below which shows how to use the widths of the characters from the metric block. In this case it is a standard ANSI font and the font data is in RAM_G (see example 2)

 BRT_AN_042.pdf

This would allow you to make a more flexible text command,

Hi,

Please note that there is a condition in the use of the wrap x and wrap y if you set them to repeat. The result is only defined if the respective dimension is a power of two,

Therefore your 9 would not give a defined result and also your 48 would be the same. As you said, it is a useful technique for a background etc. but you would need to use an image with power of two in both dimensions,

Here is an explanation from the BT81x Programmers guide,

BITMAP_SIZE:   This command controls the drawing of bitmaps: the on-screen size of the bitmap, the behaviour for
wrapping, and the filtering function. Please note that if wrapx or wrapy is REPEAT then the
corresponding memory layout dimension (BITMAP_LAYOUT line stride or height) must be power of
two, otherwise the result is undefined.

Hello,

Thank you for the clarification, I have contacted the development team to see if they can advise on this use case.

Hello,

Unfortunately it is not really practical to modify an image with a flat (black) background to make this appear transparent.

One option maybe to convert the image to ARGB1555 via EBA to include the transparent background, this should result in a better quality image when the transparent background is used. You can store this conversion in flash and load it into RAM_G when required by your application.

Hello,

Thank you for your question.

The REG_CLOCK register holds a value for the number of clock cycles since the last chip reset, and should not be used for an indication of the PCLK rate being used by the IC.

Please see section 4.5 of the datasheet for an explanation no how to se the PLCK frequency:
