I am using the STM32H743VITX MCU and TouchGFX with the display (800x480px) in a single buffer format with RGB565. The framebuffer size is calculated to be 750KB; however, the MCU does not have a contiguous 750KB region in RAM. I am exploring ways to ...

I am having trouble finding how to change the interval of the major gridlines dynamically. I am using the scrolling graph and have implemented dynamic Y-axis range, but I want to be able to change the intervals of the gridlines as well. Is this possi...

I have a dynamic graph set to scrolling. When I call graph.clear(); it will set the initial graph back to my range 0-100, but once it starts scrolling it instantly jumps to the last highest value being the start of the new range instead of continuing...

My original plan is to use the DMA. From what I've seen I thought it ill advised to not use DMA, have I been misinformed? Have you seen a Display not use DMA and still work fast enough and without any artifacts?

Thank you. I discovered that the labels and grids are not manipulated through the graph object, but look like they are their own separate objects.I was originally trying to find something like graph.setYinterval();My solution was to use graphMajorYAx...

@GaetanGodart , @Andrew Neil I discovered that the issue was occurred only when touchGFX was part of the project. I found another post and copied in their solution and It works: MPU_InitStruct.Number = MPU_REGION_NUMBER3; MPU_InitStruct.BaseAddress...

@Andrew Neil , sorry forgot to mark prev thread...The code I put in regard SD card is the same, the only difference is the new one has RTOS.I have found a very weird behavior. If I place a breakpoint on the following line in find_volume() and then c...
