Brief: This note will explain the application of emWin AppWizard on the Nuvoton N9H Human Machine Interface (HMI) Series platform, focusing on selecting appropriate hardware/software acceleration designs for different applications and designs. It aims to optimize the performance of the HMI interface and prevent issues such as screen distortion or tearing.
About N9H display capability, we measured still image display and animation display cases based on our EVB with 3 types of panels. And also measured the boundary of the pixel clock for reference, which is shown below. (All with parallel RGB "+ JPEG" means "hardware JPEG decode in the background".) .
* Underrun means the pixel clock needs to be reduced below the screen specifications to prevent display tearing. Must refer to the panel's specifications. However, lowering it may cause other problems, such as frame rate issues.
