STM32F469 touch screen

Hello,

I have the STM32F469 and I try to program it via Flowcode software by Matrix TSL. I create a code and uploaded it to the STM32F469. Now the only thing I get is black screen. Previously the module was working ok and I could work with the preloaded software. The jumpers are at their original position , as requested in the carton shipped in the packaging. 

When I plug in the module in my PC , it recognizes it and I can view the internal storage.

Only LD5 & LD6 light up

Does someone have a clue about that?

Is there a way to load again the preloaded factory code in it or other test code to test functionality?

Thank you ,

Best Regards

Hi

Achilleos.Andreas

‌,

You didn't precised which STM32F469 board you are using: is it theSTM32469I-Discovery orSTM32469I_EVAL?

For both boards, you may find the demonstration in the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef4.html

package under:

• [STM32Cube_FW_F4_V1.0]\Projects\STM32469I_EVAL\Demonstrations
• [STM32Cube_FW_F4_V1.0]\Projects\STM32469I-Discovery\Demonstrations

You have to refer to the readme file of the example for more details.

Hello,

Sorry for the late reply...  I have the DISCO board.

I am a bit confused, what is the purpose of the online compiler and what of the STM32cubeMX?

Thank you

Which online compiler? mbed you mean?

http://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-configurators-and-code-generators/stm32cubemx.html

is the

STM32Cube initialization code generator

 that allows you to configure the peripherals you need based on some wizards, then generate initialization code for your application. Then, user has to add his processing code (he can get inspired from the examples provided in the Cube package).

Thank you for you reply, I am just trying to find the examples you mentioned!
