"How can I prepare the UI for a project with a display before the display arrives?"

[jr_engr_mbed]

Hi ST Team,

I have completed my first custom board using the STM32H753BIT6, using the H753-EVAL board as a reference. I need to test its external SRAM, SDRAM, Flash, and QSPI, as I have included all the memory components present on the EVAL board. I have chosen the 10.1 " Ronbo 1280x800 (MRG10112) RGB display for my project. but I've to do use another board for lvds or rgb.because I've no pin left in my 208 lqfp h753..so, can any one suggest which external memory is enough for handle 1280*800.@ 16bit.. or is using another MCU for other added sensors is possible to get result.

Could you please advise on how to make TouchGFX compatible with this display? Is it possible to create a full GUI in the simulator and later adapt it to the actual display? Any guidance on the best approach to efficiently complete this project would be greatly appreciated.

Thanks in advance.

Best regards,

Hello @jr_engr_mbed ,

1. To help you choose external memory, we have made this documentation .
2. You can definitely use another MCU to do the sensor control and then send the result to the main board!.
3. To make your display compatible with TouchGFX you need to do a board bring up as explained in this article .
4. You can definitely create a GUI in the simulator and then import it to a "real" project. To do so, create your GUI, then open your "real" empty project, click on "Edit" => "Import" => "GUI" then select the .touchgfx file of your simulator project.

If this comment answers your question, I invite you to select it as "best answer".
