| Abstract: | The application of liquid crystal display in the electric automobile panel was presented. The information display of PCA8538 LCD on the Panel was introduced with the LM3S811 as the control core. The I2C was used to drive the PCA8538 and the speech circuit and matrix keyboard interface circuit were given. PCA8538 debugging interface was designed by VC. The panel has better display effect and more display information than the traditional panel. |
