Hello,

I want to generate a font for traditional and simplified Chinese.
this already works with the simfang.ttf and the eve asset builder.
Now we want to use other xxx.ttf files for fonts.

which xxx.ttf files one can I still use for this (except licenses)? What else do I have to consider to display the xxx.ttf files correctly?

Best Regards

Hi,

as already described, if i read out the end address i get the start address. See lines:
ParameterAddr = ((Reg_Cmd_Write_Offset - 12) & 4095);                       // Go back by 12 bytes to get end address parameter
End_Address = EVE_MemRead32((RAM_CMD + ParameterAddr));

used pic:
home_v4.jpg JPEG to show on display
home_v4_converted.jpg generated with EAB 1.0 in Output Format: PNG/JPEG (EVE Product Range: FT81x)
home_v4_converted.h generated with HxD tool

Hello,
I have noticed the following:
We use a 32bit PIC and the FT813. The communication takes place via the SPI bus with 10Mbaud.
When I convert a jpeg image in the EVE Asset Builder 1.0 with the output format PNG / JPEG, then convert the image in HxD into a hexfile and embed it in the program, the image is displayed correctly. However, the end address of the file is read out incorrectly. There is always the start address again in it. The width and height of the picture are returned correctly.
The end addresses of the png files are correctly returned (conversion in the EVE Asset Builder 1.0 to output format RGB565). The following pictures then overlay the picture because they get wrong start address.
Is that a bug or am I doing something wrong?

Best regards

Hi,

I solved the problem. PCLK for LCD LVDS driver requires a R_pullup or R_pulldown to use rising/falling edge triggered clocking. Both were placed on PCB. I removed R_pulldown and it works.

Hi,

corruption on screen if colours >190 on own board with ft813 and pic32mz2048efm144.

1)   Text APP_Text example with changes for a better indication of the error

API_COLOR_RGB(255,255,255); // terrible
API_COLOR_RGB(190,190,190); // ok

>> do all items (such as points and lines) also show corruption when any of the colours is greater than 190? <<
-   it looks like it's just in connection with text

Thank you in advance.

Best regards,
rsc

hi,

we are using FT813 and pic32mz... on own app-board for our application.
Used display is AT070MP01

timing parameters:

    while(1)
    {
    }
}

After successfully init we display same strings on display with different
text colors (see appendix).

Problem: if R > 190, G > 190, B > 190 there are distortions in the text to see with
API_COLOR_RGB( R, G, B );
Distortions on displayd lines 1), 5).

Does anyone have any hints?

Hi,

an update to issue. If I start the myProject.exe file directly from the folder myProject\Build\ME813AU WH50C\x86 Release\Bin then all pictures are shown. But that does not happen when I do build and update to hardware in eve screen designer 4.5 beta 2. For this, the images do not have to be copied again into the folder. The hint of pauljiao was very close.
Thanks to pauljiao.

Hi,

is there any hints why displaying the images fails? I had two examples (ColorPicker and WashingMachine) created and sent to you.
I have to present the results on Monday and there it is decided whether we use the graphics controller or not.

hi pauljiao,

thanks for the suggestion. Unfortunately that did not work. The pictures are not displayed

hi

we are starting a new project with EVE FT813Q. The SampleApps are working fine on
ME813AU-WH50C DEV BOARD with Visual Studio Express 2017 after updated
LibFT4222 files in EVE SampleApp projects.

Now we are using Eve Screen Designer 4.5 Beta 2 with ME813AU-WH50C DEV BOARD.
The Problem is that images are don't displayed on ME813AU-WH50C DEV BOARD screen.
ESD Labels, buttons, progress bars... will displayed on screen but all images,
widgets with images will don't displayed on the screen.

Can you help us with this issue? Should LibFT4222 files updated before starting build and updating to hardware?
