TouchGFX problem with shape element

[OShan.1]

Hello everyone!

I have a STM32H7B3I-DK board.

I use TouchGFX Designer ver 4.13.0 and created a simple project.

The project consist of one screen with two elements: box1 & image1

Also I created eclipse project with touchgfx framework, FreeRTOS and TouchGFX folder (conteins files generated by TouchGFX Designer).

Succsessfully compiled it and download hex-file to my STM32H7B3I-DK board. It work well!

After that I added a new element: shape1. Generated new code by touchGFX designer and update TouchGFX folder in eclipse project.

Succsessfully compiled it and download to my board. It dont work!

LCD screen is black.

I run TouchGFX simulator and project work well.

After that, I run target (to start TouchGFX project on my board) and as result, LCD screen is black, too

When I exclude add(shape1); from my code, it work well for both projects (TouchGFX Designer project and eclipse project with touchgfx framework) but without shape element

Why? I dont now. Help me, please.

I attached cpp, hpp files where I added a shape element to my code

Hello.

I resoved my problem by change PWR_REGULATOR_VOLTAGE_SCALE2 to PWR_REGULATOR_VOLTAGE_SCALE0.

After that it work nice.

 //__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE2);
 __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE0);

Great ! 🙂

The voltage scaling can indeed have an impact (on the APB bus frequency for example) that wasn't checked very well before CubeMX 6.0.0.
