led点阵屏程序出错请教

本帖最后由 zk16 于 2012-10-21 21:40 编辑

最近尝试用avr做点阵屏,显示两个字,写了个静态测试程序,用CVAVR编译时相应行出现了所示错误提示,请各位指教问题在那,本人初学avr及CVAVR软件,请赐教!谢谢!

原因找到了! #define G_138 PORTA.3;
               #define DATA_595 PORTC.1;
               #define RCK_595 PORTC.2;
                #define SCLK_595 PORTC.3;
后面不应该有;号的 低级错误！费了一上午时间才发现，编程不够认真，今后努力改正！
