Hi! I'm using stm32h750-custom board, and I want to show a picture on a 4.3 inch tft lcd with ltdc interface. I'm pretty sure that I adjusted ltdc setting correctly. I used image converter to convert the image (480*272pixels) and I add the exported h...
Maybe someone from Touchgfx can help in this
Hello Dear Engineers,I am looking for using DMA2D with stm32f429IGT6. So far I have been able to use RAM and LCD in cooperation. Now I want to use LVGL as the main framework. The main problem is I don't know how should I use dma2d in the bare-metal c...
Hello, I have a STM32H747-DISCO Discovery kit. I am still fairly new to STM32 so forgive my ignorance but I was wondering what is the most efficient way (in terms of cpu usage) to perform a picture perfect image upscale on a bitmap image (see picture...
HelloJust as an information; (@Alexandre RENOUX )You added the function OSWrappers::taskYield() when using L8 images.TaskYield() is called in the function setupDataCopy. The problem: setupDataCopy is also called from ISR as you know, TaskYield() is ...
I have seen this thread https://community.st.com/s/question/0D53W000007XLbHSAW/why-does-animating-an-l8-image-take-significantly-longer-than-a-standard-image which states that RGB565_L8 transformation is completely handled on the cpu without dma2d a...
I have been experimenting with animating an image onto the screen. Because I want to reduce the amount of FLASH space required, I would like to use an L8 image (I do appreciate adding this format to the TouchGFX framework, by the way).I am placing th...
There ia need to flip the display screen up and down, can I change the direction by config the TouchGFX designer proj or the STM32 LTDC or DMA2D parameters? Thanks
Hello!We are use STM32H747 and TouchGFX. We are need to use DMA2D. But we have issue with mode DMA2D_R2M.Our configuration hdma2d.Instance = DMA2D; hdma2d.Init.Mode = DMA2D_R2M; hdma2d.Init.ColorMode = DMA2D_OUTPUT_ARGB8888; hdma2d.Init.Output...
