CC1101接收不到数据的问题

我用AVR M16控制一个CC1101不停发送数据10ms间隔一个接受数据，出现的问题是接受方GDO0_H偶尔变高，但进入后接收到的字节长度为0，数据也为0，我采用的是可变地址长度+地址滤波+CRC，后来把地址滤波去掉还是如此，请教各位有没有遇到这种情况，谢谢。

出现的问题是接受方GDO0_H偶尔变高，但进入后接收到的字节长度为0，数据也为0 也发现有这个问题，这时候你去读取包状态位（0x38 (0xF8): PKTSTATUS - Current GDOx Status and Packet Status）中bit1 将置位，正常接收时该位为零的。
手册上该位描述 Not used 。也不知道啥情况，持续关注中……

关注，我上次也想用硬件SPI进行发送，也出现过能读写芯片的寄存器，但是就是没法发送的情况，弄了好久都没好，然后就换了另一个芯片了。

scty 发表于 2012-5-29 17:31:18

TI官网有全套的例程的，采用MSP430 + CC1100x系列的，使用的硬件SPI模式。

换个芯片好了没最后

liuzs09 发表于 2012-6-3 22:27:08

没换芯片，我手头一共有五块CC1101，都是这样的情况，要是都坏了那就悲催了

能给个链接吗？我在其他的地方也找到了一套据说是官网的程序，然后我把其中的一段提取出来用（原来的有点复杂，没有直接用）。就是出现我说的结果。谢谢了

你可以去官网找mrfi库，这个写的非常好，当然是在430上的，其他的话，可以自己移植
