Abstract:This paper introduces the functions and features of SED1335 Controller and its instruction system, and the characteristics of TMS320LF2407A. An intricate display project based on TMS320LF2407A controlling SED1335 is suggested. The hardware interface circuit between TMS320LF2407A and the SED1335 Controller is introduced. Interfacing technique for LCD Controller SED1335, TMS320LF2407A, methods of displaying character, Chinese character and graph are introduced. The realization means of correlative software based on C language of DSP are also given in this article. The scheme of the TMS320LF2407A chip to control SED1335 is simple, reliable, and easily realizable.
