Hi,

Could you advise what lengths of strings you were needing to use?

Hi,

I really tried a lot of different combinations and different alignments in RAM but none worked.  Can you send us an example of two different images generated separately but both loaded at the same time in memory and which would be functional on the chips.  I will also be very curious to see how did you achieve this result.  Posting them here lets us know if the problem comes from our image generation or the way we load them into memory.

Hi,

do you know if it is possible to display long texts with the BT 815 chip?  I use the Gameduino 3x Dazzler so it is equipped with 8 mega of external RAM.  if I display too much text it crashes because I suppose I am saturating the list of instructions.  List which is too small and remains a big limitation on these chips. 

Ps. my CPU is at teensy 4.0

Hi Rudolph,

Yes, 2.11.0 is now out,

We were not able to make some other changes in time for this one but rest assured your suggestions are with the R&D team for future consideration,

Well now, EAB 2.11.0 is out and it clears the Input Character file when you change fonts.
L8 is still selected when going for extended format, "Reserve Space" is still not selected by default and ASTC 4x4 is still the default.

And it still generates the 7.4MB "SampleApp" everytime.
At least there is a way to stop this, rename C:\Users\Public\Documents\EVE Asset Builder\tools\SampleApp

The needle is 600(W)x530(H) It is a red needle going vertically from about 300px down from top plus a filled circular centre area in grey. The remainder is transparent. The overall size allows the needle to display through about 270 degrees with a rotation matrix applied. (Rotated images appear to be cropped outside the original rectangular bitmap size if not rotated).

It appears that the whole area below the image comes out as pink which shows in the opposite top corner when the needle is pointing to the bottom left or bottom right. I will try making the image bigger to see if this solves this issue.

The settings for image conversion are BT81x (using at BT817) and exhaustive (tried all and get the same result).
For the flash utility Data alignment is ticked as is insert EDF block.
I've so far tried 4x4, 5x5 and 8x8 formats. Each one has differences in artifacts.

The binary file is copied to the flash as-is. The blob appears to work as the flash switches to fast ok.

On start up, each image is copied to RAM starting on a 4K boundary for each. Padding is ignored at this stage as the images all start on a 4K boundary.

Hello,

Thank you for the update, I'm glad to hear you can resolve the astcenc.exe issue.

Would you be able to provide the Conversion settings utilised in your testing? Along with the image dimensions for the needle image?

Thanks for the replies.

I suspect the first post hit the nail on the head, I use a fairly old toughbook in the lab as it has a bigger screen than the newer ones which is easier on the eyes. I re-installed on a newer laptop and the supplied one works.

The bad news is that the supplied astcenc is doing exactly the same.

I'm suspecting the problem is that this application is for custom dials so solid lines and text with sharp edges and high contrast. Not ideal for compressed graphics but there are 2.2MB in ARGB555 format. I was assuming I could display direct from flash as stated in the data sheet however when searching forums to solve the issues it has become apparent this is not the case. There should be a warning in the data sheet than only a few small graphics can be displayed direct from flash.

The workaround at the moment is to display the one causing major issues, a large needle with rotation applied, in ARGB555 which takes up 600K and then use higher compression on the remainder and crop the bottoms of the images to hide the artifacts. The customer is complaining that the graphics are looking rather fuzzy like this though.

Are there any suggested optimisation switches for astcenc to make it more suitable for this type of image ?

The only other route I can try is uncompressed / palleted to reduce the image size since there aren't a great deal of colours. Not a route I want to go as it will be more work and restrictive for future changes.

I'm under an NDA so can't post the images on here. It may be I can create something similar myself which shows the same problem.

Hello,

Can you please try the command line mode by clicking the "Command Prompt" button in the left side panel?
NOTE: Use option -x to specify the path to astcenc.exe

eab_tools img_cvt -i D:/flower-red.bmp -f 15 -o D:/work_space/output -e thorough -x path/to/astcenc.exe

Another way is to check the astcenc.exe supplied by EAB.
astcenc.exe -cl  path/to/image.png  path/to/output.astc 5x5 -fast
