Constitute LCD controller with FPGA

By a DSP (Digital Signal Processing) chip and FPGA (field programmable gate array) as the core component of the wireless digital spread spectrum communication wireless spread spectrum communication platform is an open platform, can be used for wireless access, wireless images and audio transmission, mobile INTERNET, precise regional positioning LPS, intelligent remote detection and other high-tech fields. Based on the increase in the liquid crystal display and touch screen control, which can achieve a text and graphical information editing and wireless transmission.
We the FPGA logic programming lcd module controller functions. FPGA timer interrupt DSP (DSP about 5% of the working time) to access to external RAM display data, and then, FPGA internal logic of the display data to be displayed on the LCD screen. DSP on the touch screen conversion signal processing and computing, and complete a variety of text and graphics editing tasks. That together with the DSP and FPGA controls the liquid crystal display and text editing graphic information, and to receive a touch screen signal, in order to achieve the function of handheld pen. Character LCD Modules Combined with digital spread spectrum wireless communications platform will be able to achieve a text and graphical information of the wireless transmission. The product can be used to reporters at the scene to conduct communications inconvenient text and graphics, real-time editing and coverage as well as in the process of moving text and graphic information required where wireless transmission
