Hello Team,

I have purchased STM32F7 disco board. I want to use CubeMx tool to generate code and modify/use it.

Can I get CubeMx project for STM32F7 discovery board : STM32F769i - DISCO (MB1225B)

Thank you,

Hi

arror.balaraju

,

A set of examples usingSTM32F769NI discovery board are available under the STM32F7 firmware package:

STM32Cube_FW_F7_V1.7.0\Projects\STM32F769I-Discovery

About using QSPI on STM32F7 a set of example are provided  under the STM32F7 firmware package and can be

easily tailored to any other supported device and development board.

Hello Nesrine,

Thank you for the help. I will use this example to explore QSPI.

I have other question is, can I get CubeMx project for the discovery board: STM32F769i - DISCO (MB1225B).

I want know how the components are configured in STM32CubeMx project. This I will take reference for my development.

Thank you,

Hello Nesrine,

I am sorry, I could not explain correctly.

I have some knowledge on STM32MxCube. I know how to configure components.

But in case of Discovery board I do not have schematic. If I can get cube project, I can understand which all are components are connected to the host and via which communication they are connected. How LCD is connected? Of course via DSI, that I understood. But how LTDC is controlling ?? Which buffer is used for screen composition ? external SDRAM? how this SDRAM is accessed? via FMS?? DMA?? , why QSPI is used? to execute the code or only to fetch fonts etc.

If I can get the cube project that would be great help

Thank you,

schematic is in the user manual.

and also at the board's site

drivers for the components on the board are in the board support package

Hi Nesrine,

there are no example to QSPI on STM32F769I_DISC0 ...I tried to adapter the example on STM32F769I_EVAL changing the GPIO configuration but it still don't work

Do you have a working example?
