Abstract: This paper stated the functions and features of DSP chip TMS320LF2407A and dot-matrix LCD module MSP-G320240 based on inter SED1335 controller, presented a kind of the interface design of the liquid crystal display based on DSP, introduced the circuit of the hardware interface and the design of software, discussed the resolution of displaying character, Chinese character and graph on the graphic LCD, gave relative program 、time schedule、circuit block diagram and programming process diagram. In practice, the system not only solved the driving and display problems between DSP and LCD effectively, but also saved the I/O ports, it will provide general reference and helps for various portable type system display terminal design.
