A Graphical Display Method for Low Performance Embedded Systems Based on Hybrid Programming and Double Buffering Technology

Graphic flickering is a technical problem of low performance embedded system graphics applications, and the traditional development method is more difficult. On the basis of in-depth study of the drawing principle, the use of mixed programming technology reduces the difficulty of graphic application development. And using the double buffer technology suitable for low-performance embedded systems, two drawing methods of switch and copy modes are proposed. Taking dynamic line chart drawing as an example, the effectiveness of this new method is verified.
