I'm using the STM32H7B3I-DK and having an issue I am not fully understanding. I am using the Scrolling Dynamic Graph and wanting to add some more peripherals such as SDMMC so I added a shareable region to the to my RAM.However, now whenever the graph...

I am using the STM32H7B3I-DK and trying to read and write from an SD card using SDMMC1 with TouchGFX running (also FreeRTOS). I have solved a NO_FILESYSTEM ERROR described here. While this allowed me to mount, open, and write to a file, I still get N...

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...

@GaetanGodart , the issue was as described by @JTP1 hope this helps to further improve touchgfx

@MOBEJ Thank you for you suggestion. I am having trouble finding an example with an SD card and TouchGFX that would relate to my issue.

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?

Hi @GaetanGodart ,I am unable to share the project due to business constraints. I Currently have worked around the issue by using goToScreen, but just going to the current screen to reload the entire Screen and values.I have attached some pictures I ...

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...
