Design of Display Module Based on μPSD3234A MCU and LCD1602

Based on the Keil 51 development environment,the single chip microcomputer μPSD3234A I/O interface drive LCD1602 LCD module was designed.The system is practical for single-chip microcomputer UART interface occupied breaking,with minimal microcontroller I/O interface drive LCD1602,which meets the complex circuit information needs.Compared with the traditional design method,with PSDsoft Express software for the PSD modules of the pin configuration,and the support of FLASH memory management configuration,procedures and programmable logic download,the operation is more convenient and quick,with advantages of time-saving,low consumption and high efficiency.
