iMX rt1064 GUI Application using AppWizard and SD card

[kashyap_patalia]

I am developing a GUI application around iMX RT1064 development kit (MIMXRT1064-EVK). I have use RockTech 7 inch capacitive LCD module (RK070CU03-CTG) for displaying graphics. I am using Segger AppWizard for UI design. However I am totally clueless about BSP selection in AppWizard and how to use SD card or external flash (onboard 64MB Hyper-Flash in case of evaluation kit) to store all UI resources which will include all images, fonts and some gif files to be displayed on LCD.
After so many efforts, I was able to bring up the 7" RockTech dispay module and I have also ported the touch driver for GT911 IC.

However the SDK and the resources on NXP website totally lacks all the details about how to bring up custom or other LCD modules using lcdif interface other than what is provided with the evaluation kit. Also it lacks the resources of how to use AppWizard properly and how to use incorporate various external memories for storing UI resources.

I have two rt1064 evaluation boards with me. I want to develop the UI application. Please help me.

Hi @kerryzhou .

Thank you for the quick reply.

As I have already mentioned that I am now able to display graphics on my 7" inch display. Now the bottleneck for me is more about the GUI application size and storing of the UI resources (inages, gifs, fonts, etc) to the external memory. I have 2 options (SPI flash and SD card). I am unable to find any viable solution that mentions how to store them externally and load them in code. As the NXP has already partnered with segger for AppWizard full support, can you please guide me about how to store the UI resources onto SD card (or any external memory) ?

Thanks again.

Hi @kashyap_patalia 

  About the UI resources onto SD card, do you know the detail data in the code? If yes, you totally can write it to the SD card, about the UI, eg, 

it has one item to select show text from SD CARD, whether this meet your demand?

Best Regards,

Hi, @kerryzhou 

Thanks for the quick reply.

Exactly this is the bottleneck point. After selecting this 'Show text from SD' what next steps should be taken. Same question for 'Show image from SD'. After selecting this option would the AppWizard itself place all the marked UI resources to the SD card connected to RT1064 or the developer will have to store them manually. And if manually, then at which location (exact path in case of file system) ?

TIA.

Hi @kashyap_patalia 

  Please read the AppWizard related document at first:

https://www.nxp.com/design/software/embedded-software/nxp-emwin-libraries:EMWIN-GRAPHICS-LIBRARY?fps...

UM03003, AN03003

That Segger document has more information about the sd card selection.

Wish it helps you!

Best Regards,

Hi @kashyap_patalia 

Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.
About the LCD, we have an application note about it:
https://www.nxp.com/docs/en/application-note/AN12302.pdf
About the Segger appwizard, I think you may mentioned the emwin, you can refer to this video:
https://www.nxp.com/design/training/mcu-tech-minutes-gui-development-with-emwin-and-appwizard:TIP-MC...
There has 6 video about it.
Community also have some link:
https://community.nxp.com/docs/DOC-346204
You can refer to it.
If it can't meet your demand, as you know the GUI is from emwin, you also can check with segger side, whether they have more information you needed.

Wish it helps you!

Best Regards,

Kerry
