I have been able to get the slider position using a callback function but need to set the slider position when the page is shown from a stored value. I don't need continuous updates only when page is activated.Thanks

I am integrating a TSC2007 touch controller on a Nucleo H7A3 board. I have created a simple test screen with TouchGFX. I also created a driver that senses touch from the TSC2007 via a GPIO pin and added the X and Y state values to the STM32TouchCon...

Nucleo-H7A3ZI-Q dev. board with LTDC configured. I do see Vsync and Hsync pulses going to the display but the VSync is not triggering the queue so it hangs. I traced into that call and it looks like it is waiting for an IRQ.

In the cubeMX FMC configuration I don't see SDRAM listed.

That worked like a champ.I save the value in EEPROM and after a power cycle I read the EEPROM and set the value back to what was saved.I did have to remember to set the external EEPROM read/write functions as extern "C".Thanks a million.

Thanks. I originally started with that arch but got lost. I watched a video and was able to setup MVP as here (minimal code shown) and it does work:void Model::tick(){ modelListener->UpdateValue(CurrentBrightness);}void Model::ValueChanged(int valu...

For anyone needing help with this I did the following and it works as expected:This was for a screen brightness setting slider with a saved value called Current_BrightnessI used callback functions the same as getting a value from a widget.Create a fu...

I did see that but wasn't sure how to implement it in my code. I will try using that Thanks

Follow up question. Might be related. I see in other examples RENDER_TIME_Pin and VSYNC_FREQ_Pin. What are these and what do they connect to? My app does not have those.

How to set the slider position from code.

How to interface TSC2007 touch controller

osMessageQueueGet(vsync_queue, &dummyGet, 0, osWaitForever); does not return in the OSWrappers::waitForVSync() function.

I'm using an STM32H750B-DK for my project with 800x480 LCD using ext. SDRAM for framebuffer. I was only able to get the STM32H750VTB6 device for final production. When I build that device I get framebuffer to big. How do add an ext. SDRAM to the VTB6?
