Abstract
In order to control the TFT-LCD,a design method of TFT-LCD controller is introduced, with the STM32 and the CPLD as the core controller,along with an external SRAM as the display cache.Firstly,the overall architecture of the design is analyzed.The communication protocol between STM32 and CPLD is drawn up inside of STM32.The drive of LCD timing,the parsing of communica-tion protocol and the reading and writing of the SRAM are implemented by the CPLD.At last,the LCD timing and the reading and writing of the SRAM are simulated,and the figure of the actual oper-ation effects are shown.The results indicate that the TFT-LCD can show the picture and word cor-rectly controlled by the proposed design method.The method is of simple structure,high cost per-formance and higher application value.关键词
