一、
main.c(35): warning: #128-D: loop is not reachable from preceding code
原因，前面有一个while(1){ …….}
二、
main.c(54): warning: #1-D: last line of file ends without a newline
少了一个回车在}之后
介绍了一种基于AT89S52微处理器、键控显示模式、多汉字显示的显示模块设计方法。对AT89S52的内部功能及使用高128字节RAM时的寻址方式进行说明。给出了四汉字显示模块的硬件电路原理图、主程序流程图以及中断显示流程图。

The design method of display module base on the AT89S52 microcontroller,disp ...
The CAT93C46 is a 1 kb Serial EEPROM memory device which isconfigured as either 64 registers of 16 bits (ORG pin at VCC) or 128registers of 8 bits (ORG pin at GND). Each register can be written (orread) serially by using the DI (or DO) pin. The CAT93C46 features aself−timed internal write with ...
