C8051F9XX单片机SMBUS示例程序-Singlechip C8051F9XX SMbus sample programs

单片机是一门实践性非常强的学科,为此我们突破传统思路,全面围绕单片机试验,从简单的流水灯开 始, 逐步的带领大家从这些简单的几行或者10 几行的程序,来熟悉和理解单片机的指令. -Single-chip is a very strong practical subjects, and we break through the traditional idea of a comprehensive focus on single-chip testing, from simple water lights began to gradually lead the U.S. from these simple few lines or a few lines of 10 procedures to familiarity with and understanding of SCM commands.

PCF566是LCD液晶驱动芯片，此驱动芯片在电表行业使用比较多，上面是PCF566芯片在AVR单片机上使用的驱动子程序，可以移植到其他产品上。-PCF566 is LCD LCD driver chip, the driver chip in the meter industry more, the top chip in the AVR Singlechip PCF566 use driver subroutine, can be transferred to other products.
