在国外网站下的NRF24l01最详细的指南（含程序解释）

最近在公司实习，我一来老板就让我搞射频部分，这简直是在搞我，以前在学校我根本就没接触过这玩意，这下给我出了个大难题

chenliangmoto 发表于 2008-3-28 10:15:18

不好意思，网速太慢了，传不上

lin28 发表于 2008-3-28 10:17:21

等待。。。。。

Tutorial 1 (PIC18F452)
Tutorial 2 (PIC18F452)
Tutorial 3 (PIC18F452)
Tutorial 4 (PIC18F452)
找英文技术资料用www.yahoo.com能找到一大把在国内找不到了

这个论坛有好多讨论NRF24L01的人，令我感到新鲜的是有个中国学生叫Haihong Li发的贴子，看他的Location: North University of China，是北方大学？

ghost2 发表于 2008-3-28 10:43:33

呃，和我去的是同一个地方。
里面的24L01代码移植性很好，例子也很丰富，但是代码没有中断方式的

chenliangmoto 发表于 2008-3-28 11:10:08

我现在就是接收不了，我基本上是按照那上面的时序来写程序的，为什么就是接收不了呢？为什么呢？难道有哪里要特别注意的地方吗？能否指点一二啊

ghost2 发表于 2008-3-28 11:43:00

我的程序还没完成，也没加电测试。
楼主是用了nrf24l01.h/.c来做的么？

另外，那个North University of China我也看到了，不知道是哪家

suncq 发表于 2008-3-28 11:49:51

不错！那里有现成的模块卖？价位应该和不带L的差不多吧？

chenliangmoto 发表于 2008-3-28 12:45:44

我用AVR来控制，只是参考了那上面的程序
那里的模块价格就不清楚了，没买过

yorkbluedream 发表于 2008-5-19 20:05:03

North University of China是中北大学，山西的一个学校，Haihong Li是我一个研三的学长，我的毕业设计跟着他做，现在正在做着，大家可以互相交流！

小弟乃初学菜鸟，貌似没发现程序中有写过本地地址和发送/接受地址，哪位高手指点一下这些地址该怎么写啊？24L01的PDF中有吗？
