一个单片机应用系统的硬件电路设计包含两部分内容:一是系统扩展,即单片机内部的功能单元,如ROM、RAM、I/O、定时器/计数器、中断系统等不能满足应用系统的要求时,必须在片外进行扩展,选择适当的芯片,设计相应的电路。二是系统的配置,即按照系统功能要求配置外围设备,如键盘、显示器、打印机、A/D、D/A转换器等,要设计合适的接口电路。

ST7529液晶驱动 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

Ideal for large low power (nanoWatt) and connectivity applications that benefit from the availability of four serial ports: double synchronous serial ports (I² C™ and SPI™ ) and double asynchronous (LIN capable) serial ports. Large amounts of RAM memory for buffering and FLASH program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications. While operating up to 40 MHz, it is also backward software and hardware compatible with the PIC18F8720.
