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...
