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...
HiI have two screens A and B. On A ButtonSTART (Toggle).On B ButtonSTOP (Toggle). ButtonSTART is to change to screen B and turn on the counter. ButtonSTOP is to change to screen A and stop the counter. After changing screen A to B, ButtonSTART should...
