eGUI 3.0 demo on TWR-LCD-RGB

GeneGoff — Thu, 14 May 2015 00:03:30 GMT

I can run the eGUI 3.0 demo on the TWR-LCD-RGB just fine, but a couple of graphic objects don't show:

1) None of the Group Box Titles show but the group boxes and their content show fine. I see the title text strings in the code but for some reason they don't get displayed.

2) The OK button in the Settings screen does not show it's title text "OK", the button just shows a blank button. Again I can see the title text strings in the code but for some reason they don't get displayed.

Please explain why these text strings are not showing. All other text strings for the various objects display fine.

Hi Gene Goff,

Which version of MQX and which IDE are you using? Could you please attach the project?

Thanks in advance,

Earl.

I'm using MQX 4.1 or 4.2 (I'm not at the workstation right now), the latest IAR Embedded Workbench for ARM (7.3 ?), and the project is the stock Demo included in the latest eGUI version 3.0 available at www.freescale.com\egui.

Hello,

You should use the latest version:

https://github.com/Gargy007/eGUI

This project moved to Open Source.

Luis

Actually, the eGUI I'm using was obtained from github last week. Thanks.

Hello Luis,

I'm just getting to know eGUI and I have a couple of questions that I hope you can help me with:

1) Do I necessarily need to use MQX or can I make a simpler application just using eGUI and CW?

2) How am I supposed to arrange the D4D files in a CW 10.6 Bareboard project?

3) I am working with the K70 tower module and the TWR-LCD-RGB and I want to display a single picture for now. If I use the Freescale Embedded GUI Converter, I can get the code for any picture that I want. Which is the code structure that I need to use in the main in order to call this .h file that the converter returns and display the picture?

Thank you in advance!

Elisa

Hi again Gene,

I downloaded the eGUI from Gargy007/eGUI · GitHub, I ran it in IAR 7.40.2.8570 with MQX 4.2 and the demo shows the group box titles and the text's buttons OK.

I took these demo's photos. If you have problems please attach some photos to see the demo's behavior.

Best regards,

Earl.

Hi Elisa,

1) As far as I know the D4D libraries are intended to be used on an RTOS in this case MQX

this is the structure of the D4D files in the project .

3) you can have a file with all the Bitmaps, for more information about how to show them check here.

there are the macros that are used to declare the pictures and show them and how you are supposed to use them.

Regards.

Jonathan

Thanks Earl!

I just now downloaded eGUI 3.0 again from Gargy007/eGUI · GitHub, compiled it in IAR EWARM 7.4, and ran it on the TWR-K70 with the TWR-LCD-RGB and attached is a photo of the Settings screen. As you can see, everything displays and works fine except none of the Groupbox titles show, and the OK does not show but the button still works. Also, after loading the ALL_SYS....TXT file it shows blank in the left window pane regardless of ASCII or Unicode selection. The TXT file appears to be loaded fine because it says it's size is 338B.

Thanks for your help,

Gene

Hi again Gene,

Please be sure that the SD card is inserted when the demo starts and be sure that the files "Arial8.d4l" and "CourierNew8.d4l" are located in the path "SDCARD:/Fonts/" (the files that you need in the SD card are located in "eGUI-master\_Official_Demos\EGUI_Demo\SD_Card_Content\Fonts" in the repository that you downloaded from Gargy007/eGUI · GitHub).

Regards,

Earl.

Hi Elisa,

1) No, eGUI supports bare metal, you don't need an OS. You can find a K70 example here : https://community.freescale.com/message/363679#363679

It is using PE, but using PE is not mandatory.

2) Check the project in 1)

3) The code is the same in bare metal or using RTOS.

Declare piture:

D4D_DECLARE_STD_PICTURE(board, BRD_POSX, BRD_POSY, &bmp_table)

Add picture to screen:

D4D_DECLARE_STD_SCREEN_BEGIN(screen_main, ScreenMain_)

D4D_DECLARE_SCREEN_OBJECT(board)

D4D_DECLARE_SCREEN_END()

Luis

That was it! Thanks Earl! Now I see the FONT_SYSTEM_SMALL was referencing a file using D4D_DECLARE_FONT_FILE rather than a font descriptor. I don't know how the project knows to get the file from the SDCARD:/Fonts folder.

In the archive "D4D_Configuration/d4d_user_cfg_app.h" is defined the macro D4D_FNT_WORK_PATH_DEFAULT (by default its value is "A:\\Fonts\\") which is the root path for the fonts.

Earl.

Sorry Earl. I don't care for the new Community web UI. Sometimes it gives a Correct Answer button and sometimes it does not. For example I just clicked Correct Answer for one of your replies, but there was no Correct Answer button given for your reply "In the archive "D4D_Configuration/d4d_user_cfg_app.h" is defined the macro D4D_FNT_WORK_PATH_DEFAULT (by default its value is "A:\\Fonts\\") which is the root path for the fonts."

Also, under Actions, it gives "Mark as helpful" as an option, but not an option to mark as correct answer.

I'll keep looking for the Correct Answer button to be sure to give credit for the help. Thanks!

Hi Luis,

Thank you for your explanation. I have been able to load the example in the K70 and the TWR-LCD-RGB and it was working just fine. However, when I created a new project in the same workspace, the example project began to throw some errors in the processor expert components. Should I not create different projects in the same workspace when working with eGUI?

And if i want to load a picture, I supposse I should declare it in the main file. Am I right?

Regards,

Elisa

Hi Elisa,

No, you should be able to have more projects using eGUI and PE in the same workspace.

And yes, you have to declare the picture and of course generate it with the EGUI converter.

Hi Luis,

I'm struggling with this.

I am trying to create my own project using the one that you recommended as a template. When I added the D4D files, I was getting a lot of errors regarding the inclusion of the files, so I changed the ARM Compiler options and now I don't have such errors. However, I am getting 78 errors regarding the low level drivers files (hw_iic.c, d4dlcdhw_k70_lcdc.c, and d4dlcdhw_twrrgbb.c). All these errors are due to undeclared variables and functions that are used in the D4D files, but I have not modified those and have no idea what I'm doing wrong.

What am I suppose to do with these errors?

Regards,

Elisa

Hello Elisa,

Are you able to import, build and debug the project in the community as first step?

Best Regards,
