Discuss STM32 and TouchGFX implementations, including configuration, debugging, and optimization.
We wish to always improve our documentation. The best reviews and critics always come from the people that read it, so we would like to use this post to collect your thoughts and feedbacks. Please share what you like, dislike, what you think is missi...
When creating a UI project, you may need widgets that are not part of the TouchGFX library. To create your own graphical element, the TouchGFX team suggests using the Custom Container approach. Since TouchGFX 4.20 it is possible to export and import ...
Hi I have doubt in MIPI_DSII Have only one lane but my Display has 4 lanes I don't know how to connect them bothPlease help me to interface the display with MCUor Else, please suggest to me some OLED display to interface with this MCU(MIPI-DSI)
Hi, I'm using a STM32F429ZIT6 controller to interface an OV5640 camera module. I'm interfacing the sensor over 8 channel DCMI. I'm trying to capture RGB565 at high resolution. I'm using DMA with the double buffer on the fly address update feature. I ...
I am receiving corrupt images from OV5640-STM32F4. This isn't regular, I get proper images of resolution 320x240 to 5MP, but occasionally I keep receiving corrupt images. The corrupt images are found in all resolution. By corrupt image I mean, someti...
So I bought STM32F769 Disco board which come with LCD 800 x 480 size. But then the project decide to use smaller LCD size say 480 x 272. Can use the same display for this? So in away, I dont mind to see the application graphics shown by portion of th...
So I am using STM32f769 Disco board, first I use template project from TouchGFX Designer and so far it is good. But then I realize it is using framebuffer located on external SRAM address 0xC0000000. But I want to change the location to internal RAM ...
Thank you for helping.I want to access common variables on several screens (View).How do I pass a variable to View?Will it be passed to the base class of View?I want to make it a smart way without using global variables.Thank you.
Hellovoid MovingStep_Container::SetStep(uint16_t data) { Unicode::snprintf(MovingStepTextBuffer, 20, "%d", data); MovingStepText.setWildcard(MovingStepTextBuffer); MovingStepText.invalidate(); }Unicode::snprintf(MovingStepTextBuffer, ...
Hi,I am facing a strange cache problem. I use the DCMI coupled to the DMA in order to acquire an image into the external SDRAM. As indicated in the application note AN4839, I proceed in this way.before to start the DMA transfer I clean the cache (cac...
Hi, I am trying to use the ST-CUBE-EEPROM driver to store some settings with touchgfx 4.16.I have a separate section defined in the linker script, 24kB for 500 variables at the end of the internal flash. It works well if I run it before the touchgfx ...
Since a few days I own an STM32H735 Disco board. But I can't get HAL DMA2D to work correctly. The following code shall copy a line of pixels from RAM into the framebuffer:DMA2D_HandleTypeDef hdma2d; static void ConvertLineToRGB(uint32_t *pSrc, uint...
