哈哈 盼到啦
审批通过者名单(截止至3月15日10点)
有我的名字 ,
but 居然,
还有和我名字一模一样的人一起呀
还好公司不一样
不然,奖品会发错的哦 , 呵呵
预祝, ARM开发板DIY 活动圆满成功
像朋友借了个TQ2440板子,
先编写模块程序
做些小测试
我想arm芯片应该也是大差不差吧
希望对后面的进程有所帮助

今天上班不久,就收到短信,说今天开始将收到基础包
不到10分钟,
快递小伙就过来了
没想到 就到了
鸡动呀
收到的器件清单如下:
和我之前的理解不对
之前以为,基础包还包含可扩展的器件
看来以后得认真的读读论坛公告呀
还好板子没那么快到,
这两天可以去下电子市场,把需要的东西在不上
不容错过呀·····
