Title: VEHICLE DISPLAY DEVICE
Abstract:
Provided is a vehicle display device such that the responsiveness of communication between a main microcomputer and a sub microcomputer is improved. The vehicle display device (10) is equipped with a main microcomputer (20) that generates information data and a sub microcomputer (30) that generates an image to be displayed on a display element (40) on the basis of the information data. Between the main microcomputer (20) and the sub microcomputer (30), at least a signal line for data transmission and a signal line for chip select signal transmission are connected so as to allow communication between the main microcomputer (20) and the sub microcomputer (30). The vehicle display device (10) synchronizes a first timer counter (22) counted by the main microcomputer (20) and a second timer counter (32) counted by the sub microcomputer (30), in response to the tip select signal transmitted to the sub microcomputer (30) by the main microcomputer (20).
