基于MSP430单片机最小系统板，利用HC595芯片的串转并功能，通过双片HC595，实现LCD12864的显示，减少单片机IO口资源的占用，实现了只用三个引脚来控制LCD12864，特别适用于G25XX系列的MSP430单片机-Turn and function based on the MSP430 microcontroller minimum system board, the use of the HC595 chip string through the two-piece the HC595 LCD12864 display to reduce the occupancy of the single-chip IO resources, using only three pins to control LCD12864, especially suitable for G25XX MSP430 MCU series
