In embedded applications, the serial LCD simple wiring, easy programming can meet the practical needs of the embedded device and have broad potential applications. This paper designs and implements a serial LCD Linux driver based on OMAPL138 platform, introduces OMAPL138 platforms and serial LCD configuration. The key technologies of serial LCD are analyzed, such as FrameBuffer, DMA and SPI. The basic structure and operation of the driving process are described, and the design availability is verified based on theoretical calculations and actual uses.
