Discussion - EVE / Re: ESD image rotate widget not rotating?
« on: July 01, 2021, 04:37:20 PM »
Hello,

ESD 4.xx does include support for EVE3 and EVE4 modules, however it doesn't specifically support the EVE3x‐43G from Matrix Orbital.
If this display uses the same display settings as one of our development modules you should be able to utilise this platform, however the generated code may need modification if the display settings vary from any of the modules included by default in ESD.

Discussion - EVE / Re: Using flash for bitmaps
« on: June 30, 2021, 04:25:55 PM »
Hello,

Thanks for the update.

I decoded your commands and it gave the following:
Code: [Select]
CMD_DLSTART()
CLEAR_COLOR_RGB(48,96,144)
CLEAR(1,1,1)
BITMAP_SOURCE(524416)
BITMAP_LAYOUT(31,496,372)
BITMAP_EXT_FORMAT(COMPRESSED_RGBA_ASTC_12x12_KHR)
BITMAP_SIZE(NEAREST,BORDER,BORDER,372,372)
BEGIN(BITMAPS)
VERTEX2II(100,100,0,0)
DISPLAY()
CMD_DLSTART()
Using the above display list I was able to recreate the behaviour you were seeing.

After some testing it appears when using ASTC images the LAYOUT commands height parameter must be set to the height divided by the ASTC block size, in your case this would be 31 (not 372). Using the following command in ESE resolved the issue for me:

Code: [Select]
BITMAP_LAYOUT(31,496,31)
I would recommend however utilising the CMD_SETBITMAP command to mitigate any similar future issues:

Code: [Select]
CMD_SETBITMAP(0x800000 | 128, COMPRESSED_RGBA_ASTC_12x12_KHR, 372, 372)
BEGIN(BITMAPS)
VERTEX2II(100, 100, 0, 0)
CMD_BITMAP will automatically configure the BTIMAP_xxxx calls related to the image.

Hello,

Thanks for the details, but I was looking for the code used to display the image, could you provide this?
Sorry if I was ambiguous in the previous post!

Hello,

Thank you for the update.

I will  need to clarify with the development team, but I believe that the image will scale to a multiple of the ASTC block size used during conversion.
In this case it may be beneficial to use a compression scheme which is divisible by the size of the bitmap being used.

I gave the attached image a try on EVE Screen Editor both with a native conversion and a conversion carried out in EVE Asset Builder, and I couldn't recreate the behaviour you are seeing.

Could you provide the display list you are using?

Hello,

Don't worry about it, I made the same mistake!
I will see if we can get the documentation updated to make this more clear.

Hello,

I had had a deeper look at the code used to generate a rotated image in ESD and the value range for the RotateAngle field is -65536 -> 65536.
Which values were you testing?

« on: June 25, 2021, 10:32:13 AM »
Hello,

My apologies, I misread your question and assumed you were using EVE Screen Designer, unfortunately it is not possible to create a custom widget in the same manner in EVE Screen Editor.

what are you trying to achieve with a custom widget?

Hello,

Thank you for the observation, I have tested this and can see similar behaviour.

I will contact the development team to see if they can confirm this bug.

Hello,

Could you share the options you have used in EAB to generate the ASTC output?

Please note: CMD_FLASHWRITE will erase the flash IC before performing the desired write, please use CMD_FLASHUPDATE to load the image data to the flash IC if you are not writing the flash IC with a .bin image (including .blob) file generated from EAB.Can you update your code to use the CMD_FLASHUPDATE command?

Also, yes you will need to load this data into RAM_G so that it can be written to the flash IC using the CMD_FLASHxxx commands. Please also pad the data to the next 256 byte multiple, some details can be found in the programmers guide:

General Discussion / Re: Bitmap conversion
« on: June 21, 2021, 03:53:50 PM »
Hello,

EVE Screen Editor has a built in asset convertor and bitmaps can be converted by adding them into the project via the 'content' tab on the left hand side of ESE. Please see the user guide for details:
https://brtchip.com/wp-content/uploads/Support/Documentation/Programming_Guides/Modules/EVE/BRT_AN_037_EVE%20Screen%20Editor%204.0%20User%20Guide.pdf

As for creating a text box input, unfortunately ESE does not generate dynamic screens or the logic to update a screen based upon user input. But for your end application I would suggest looking at utilising the CMD_TEXT command on your screen along with the CMD_KEYS widget for character input, you could dynamically update the text displayed via CMD_TEXT based on which keys the uses presses. Please see set_01.c in the main EVE sample applications for an example of the CMD_KEYS usage:

Discussion - EVE / Re: How to make a selected color transparent?
« on: June 21, 2021, 01:49:13 PM »
Hello,

Thanks for the details, the developers have investigated this behaviour and noted that it is outwith the intended use case for CMD_SETFONT2.

The suggest converting the PNG with the black background into an L8 formatted bitmap, and not this should achieve the same effect (removing the background and making the image transparent).

Hello,

Thank you for the update, I'm glad you have managed to get the flash into FAST mode.

Are you still struggling with displaying images from flash?

Hello,

Thank you for the update, I do not see any issue sin how you have sequenced your commands.
However please note that the .blob file must be written to the flash IC for you to be able to place it in FAST mode, I've replied on your other post on how to upload the flash .blob file if you are not using a flash image built from EAB which incorporates this.
