ABSTRACT
LCD module due to special connections and special equipment is not required for everyone to understand, so even though it is already widely used, but users in the use of, the assembly found it difficult. To the user ease of use, the need for liquid crystal display devices and control, driver integrated circuits mounted together to form a feature. The driver's role is to make this feature to work stable and orderly, accurate display. A kind of data acquisition system based on ARM Micro-controller LPC2214 is introduced in this essay. The design introduced in the dot matrix graph LCD module and its application of the chip functions based on the principle, The overall design plan is mainly in view of the liquid crystal display module controller driver .
