Hello,

Yes unfortunately, you would need to create your own spinner widget if you wish to scale it.

Below we have the raw code output for a given CMD_SPINNER (CMD_SPINNER(533, 251, 0, 0)) command:
CLEAR(1, 1, 1)
VERTEX_FORMAT(2)
POINT_SIZE(240)
BEGIN(POINTS)
COLOR_A(64)
VERTEX2F(1604, 1143)
VERTEX2F(1731, 1091)
VERTEX2F(1783, 964)
VERTEX2F(1731, 836)
VERTEX2F(1604, 784)
VERTEX2F(1476, 836)
VERTEX2F(1424, 964)
VERTEX2F(1476, 1091)
MACRO(0)
MACRO(1)

You can adjust the point sizes via the POINT_SIZE command and alter the vertex commands to reposition the sippner dots.

The MACRO(0) register is updated with the COLOR_A command scaling from 255 - 128 - 64 - 0 and the MACRO(1) register is updated with the vertex point of the dot you wish to highlight in the spinner animation.

Hi,
Could you advise on what the implementation of your text command is in your library?
For text, make sure to terminate the string and to pad the string so that the whole command is a multiple of 4 bytes (or ensure the next command begins at a 4-byte aligned address in the command buffer, depending on how you do your RAM_CMD writes).

Hello,

Thank you for the details, i believe that modules utilises a ILI2131A touch controller, this was designed by Riverdi and Ilitek to emulate natively supported touch controllers.

I am checking if we have a module which includes this touch controller for testing.
In the meantime do you have the ability to take an I2C logic capture of the touch controller data lines?

Hello,

Yes this is correct, the only way to perform a register read from a display list or via the co-processor is with CMD_REGREAD or CMD_MEMCPY.

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

Hi Florian,

For your images, is the issue related to their storage within flash or is it when you load them to RAM_G in consecutive locations?
Depending on where they are stored at the time of displaying, it may be a data alignment issue.
Does the first one display correctly but the following images are not displayed correctly?

Hi Rudolph,

Please note that the OPT_RGB565 is for JPEG decode only and not for PNG. Therefore, as you mentioned, it will not work for PNG.

We have added a note about this to the Programmers guide for the next version as it wasn't clear from the current version that it was for JPEG only,

Thanks, we appreciate your feedback,
