Design of a Host Monitoring Secondary Screen Display System Based on Embedded ARM

For real-time monitoring of hardware parameters during full screen processing tasks. This article designs a real-time image transmission system based on ARM, which can achieve the display of image information on the secondary screen of the host monitoring. By calling the open hardware monitor dynamic link library to obtain host hardware information, converting the information data into images, connecting the display screen through the UIBHID interface, using a custom TFT screen communication protocol, sending data to the secondary screen, and achieving listening to host hardware data without affecting the main screen task, and verifying it through experiments. The results show that this method can achieve real-time display of host hardware parameters on the secondary screen, and has the advantages of low power consumption and low cost.
