CC1101状态寄存器读取的值很奇怪
对主要配置寄存器的配置如下。现在的问题是，发送部分，在CC1101初始化后，我在主函数中 halSpiStrobe(CCxxx0_STX); 使其为发送模式，然后读取halSpiReadReg(CCxxx0_TXBYTES),显示的值为0079，如果在这条语句之前加上halSpiStrobe(CCxxx0_SFTX);清空;则TXBYTES显示为0015，TXBYTES理论值应该是在0到64之间不是吗？这两个值很奇怪。
还有，如果在设置为发送模式之后，读取 num=halSpiReadReg(CCxxx0_MARCSTATE); 仍然显示0079，按照datasheet上，应该是显示0x13表明在TX模式，不符。
spi读写等子函数都是参照ti提供的例程。接收模块也有类似的问题。所以现在发送接收还不能正常工作。求指导！

RF Register Setting 跟最新的 SmartRF Studio 里面导出的对比一下。
现在问题解决了，竟是电源问题。换了一个比较稳定的电源，可以了。。。
恭喜，谢谢分享！
