I've asked around the office a bit, and it's not clear what causes this.Can you try to set your QSPI to the higher clock again?Do you also have the problem if you lower the alpha value of the text field?Another thing that may cause this is that in yo...
You could use a transfer complete interrupt on the DMA to increase performance by moving the update code to a dedicated screen transfer function that can take a variable to control which half of the pixels to transfer. That would free up some CPU cyc...
Is that a static text or a number that increments? Are the artifacts consistent; in this case the 1 is correct, are all 1s correct? Are all 2s broken in exactly the same way?Be aware that for normal DMA you may run into an issue with the number of bl...
Yes, that is the setting I was referring to. You should ensure that DMA2D is enabled in your initialization code. The settings don't matter, TouchGFX will take care of this, as well as setting up transfers to the frame buffer.You should not reconfigu...
That is odd. I'm back to some sort of buffering issue. TouchGFX can use DMA2D to fetch the bitmap in extflash and copy it to the framebuffer. I can see you have that turned off in your TouchGFX configuration. What happens if you turn that on?
