Application | This example code demonstrates how to perform partial screen updates on the LCD using GDMA with emWin AppWizard on the M55M1 series microcontroller (MCU). |
BSP Version | M55M1_Series_BSP_CMSIS_V3.01.003 |
Hardware | NuMaker-X-M55M1 |
This sample code demonstrates how to update an LCD display on the NuMaker-X-M55M1 development platform using emWin AppWizard together with GDMA (Graphic Direct Memory Access). Compared to traditional software-based memory copy methods, the parallel processing capability of GDMA effectively reduces CPU utilization. By minimizing the image rendering workload on the CPU, it frees up processor resources for other tasks. This ensures that the system maintains overall smoothness and real-time responsiveness during GUI (Graphical User Interface) execution, making it an ideal practical reference for high-performance embedded systems.
