你用的是JLINK V?

                                 很不错

是在应用程序中用，截取RETAILMSG输向串口的信息，然后保存进文件，或在界面显示

                                 怎么没人帮忙解决一下啊。

                                 原创？支持

友情帮顶！ 同时我也很感兴趣。

USB转串口线绝对没有物理串口稳定，但是市面上15元左右的勉强还是可以用的，里面都是一片pl2303；还有一种串口线是ft232芯片的那种质量会好很多，不过那种好像要80多元

跟一下touch driver的mdd层

楼主要不用JTAG把NandFlash擦除干净试试。这样应该可以，因为SD卡找不到了NandFlash上的参数了，就会使用默认值吧

                                 

说“ST司方”也不一定有人信啊。 正像16楼说的，这个产品还没有正式发布、还没有上市，怎么就卖断货了呢？如果真是这样ST司方也不必发布这款产品了，反正不愁没有买主，哈哈  ...

又道听途说，有个叫什么龙芯的做电表的公司就是用的一款别人根本买不到的但确实是ST出的48腿和STM32有点类似的片子，但不是这个，因为没带液晶驱动。或许那个是“ST司方也不必发布”的定制品吧？

我做的项目就有这个功能，pc机上的还没做

高人指点一下吧，谢谢啦

一般也没人直接用51 IO口直接驱动 ，都会加上驱动芯片

SAA7130 ？ 条码扫描模块吗？ 帮顶下、MARK \ \ \

引用 10 楼 wswwxk 的回复: 先安装Active Sync 4.5，在看连接时VS2005报的什么错误啊？

Active Sync我已经装了，连接vs2005时提示：连接失败，设备未就绪

引用 8 楼 wolfmvp 的回复: 正确的步骤为： 1、安装对应平台WinCE5.0的SDK包 2、在该SDK包上编译相应的程序 顺便提一下，如果平台不一致，用EVC编译时会有提示的哦，楼主没有遇到吗？

如果没MFC组件我可以加文件进去吧？

引用 3 楼 arnold9009 的回复: 区分每一位是通过采样，串口模块检测到起始位之后，按照设定的波特率进行采样来获取传输的数据； 每个字节的前后都有起始位和停止位，串口模块通过这两个标志来判断字节的开始和结束

请问这个采样，是一个位传输的时间段内多次采样，还是只采一次。 再就是能不能不用采样这样的很模糊的概念，直接用什么器件导通，使什么获得高电平这样的描述更容易理解一些。

                                 #define 那一行的最后不能以分号结尾，否则在哪个编译器下都不能通过(包括KEIL)！
