我选的是AT89C52，按理来说128B的RAM是够得啊，为什么编译不了。直到我把其中一个数组的长度从9改为5，变成如下才能通过编译：
  1. Build target 'Target 1'
  2. compiling caiping.c...
  3. linking...
  4. *** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
  5.     SEGMENT: ?PR?_H_LINE?CAIPING
  6. Program Size: data=111.4 xdata=0 code=6491
  7. creating hex file from "caiping"...
  8. "caiping" - 0 Error(s), 1 Warning(s).

数组改为长度6也是不行的：
  1. Build target 'Target 1'
  2. compiling caiping.c...
  3. linking...

程序里写的有些函数没有被调用到！
