    9. ds18b20的诡异问题 14/5231 嵌入式系统 2010-02-01
      引用 8 楼 lin0119 的回复: 你读出的序列号的检验码是不是正确的?
      没问题
    10. wince 6.0的ie是否就没有这样的问题啊?
    11. AVR中IO输出频率的问题 4/3029 嵌入式系统 2010-01-23
      好啊
    12.                                    现在我可以确定的是A 板和B板都能正常工作的,我在程序里加了指示灯。B板可以确定是没重启
    13. 大家讨论下如何系统升级的问题 22/6381 嵌入式系统 2010-01-22
      引用 15 楼 hao507 的回复: 我们现在的升级方法是增加一个homekey,开机按住homekey进入升级菜单,然后就是通过SD卡来升级,可以升级BootLoader和NK。不知道我们的这种方法是不是最优的~~~大家一起讨论哈!
      这个方法似乎可行,不过俺还没有想到要升级bootloader的地步呵呵
    14. 汇编问题~ 5/2884 嵌入式系统 2010-01-04
      其实最好还是看 英文的比较权威,你如果安装的是ADS,那在它的安装包下有个文件夹中全是开发指导手册,里面内容足够你学习了,嘿嘿
    15. 学习应该是大部分自己努力,别人再点拨一下
    16. 帮顶一下.
    17. Happy New Year
    18. 请教关于485通信的地线的问题 4/6216 stm32/stm8 2009-12-23
                                       可能是我的电源模块设计的有问题吧,电脑和板子共地时,A,B压差为0.55V,不共地时压差为0.99V。而且只有在共地时通信才正常。 唉,不知道怎么回事啊。我试图在A,B之间加个电阻稳定压差,但是也没用。
    19. 再问个关于keilC中内嵌汇编的问题 5/3573 嵌入式系统 2009-12-21
      不要那个RET 看看这篇文章吧 http://hi.baidu.com/mikenoodle/blog/item/a9d1a30fc5a28fe7ab645786.html

      引用 1 楼 91program 的回复: 请问,你下载的是什么模拟器?
      我选择的设备是 CHSINT SDK For WinCE 6.0 Emulator 当我连接时,输出窗口的调试信息如下: (CoreCon) Transport service map set to NONE; ignoring KITL connect request!
