I started out by using the stock 4.3" display on the STM32H735G-DK Discovery Kit and with TouchGFX I was able to get a nice example project running. Now I am attempting to interface a 7" 800x480 LCD panel with the kit. This panel uses the EK9713CA ...
I've been able to successfully use Bitmap::dynamicBitmapCreateExternal() when just loading a bitmap in the frontendappliation and setting up the cache there...FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap) : FrontendApplic...
Hi,I've recently migrated to TouchGFX v4.25. The changelog seems to indicate that we can now store our texts in an unmapped external flash, for example an SPI flash. When going through the following page of the documentation :https://support.touchgfx...
