你好
我想加你qq买程序

刘海龙 2017-6-18 21:50

把下面这段程序删掉，#if (MAIN_Fosc >= 24000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_30MHZ
#elif (MAIN_Fosc >= 20000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_24MHZ
#elif (MAIN_Fosc >= 12000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_20MHZ
#elif (MAIN_Fosc >= 6000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_12MHZ
#elif (MAIN_Fosc >= 3000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_6MHZ
#elif (MAIN_Fosc >= 2000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_3MHZ
#elif (MAIN_Fosc >= 1000000L)
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_2MHZ
#else
      #define             ISP_WAIT_FREQUENCY       ISP_WAIT_1MHZ
#endif

大神,求指教下,用你的程序编译时怎么会显示如下的警告,有什么要注意的吗？还是我哪里出错了.
Build target 'Target 1'

具体是这里的问题:

#elif (MAIN_Fosc >= 20000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_24MHZ

#define ISP_WAIT_FREQUENCY ISP_WAIT_20MHZ
#elif (MAIN_Fosc >= 6000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_12MHZ
#elif (MAIN_Fosc >= 3000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_6MHZ

#elif (MAIN_Fosc >= 1000000L)
#define ISP_WAIT_FREQUENCY ISP_WAIT_2MHZ
#else
#define ISP_WAIT_FREQUENCY ISP_WAIT_1MHZ
#endif
求解释下,谢谢!!!!!!!!!

你好，请教下，这个在转HEX时怎么会显示警告的，要怎样处理，刚学的STC。

你好，我要做个电子温度计，有个两线温度传感器，想请问下是不是需要通过模数转换电路才能接到单片机上，是的话能不能给个转换电路图，拜托大神了

你好，能请教你，我要做个基于单片机模块的温湿度监测系统的设计，单片机为AT89C51，显示是由六个八段数码管显示。我该用哪个温湿度系统
