我现在使用CC2500的无限数据包模式,我想请问的是:CC2500的无限数据包模式,项目需要发射字节数为600bytes,但是CC2500只有64bytes的FIFO,当开启CC2500的时候,只发送装载到FIFO里面的数据是吗?我的理解就是将FIFO里面的数据重复发送无数次??
或者我想知道的是,在无限数据包模式下,数据怎么装载到CC2500中去?
Viki Shi:
你说的是Continuous Transmissions吧?请看具体描述:
In data streaming applications the CC2500 opens up for continuous transmissions at 500 kBaud effective data rate. As the modulation is done with a closed loop PLL, there is no limitation in the length of a transmission. (Open loop modulation used in some transceivers often prevents this kind of
continuous data streaming and reduces the effective data rate.)
Viki Shi:
如果是指infinite packet mode,数据的装载请参考数据手册15.2.2 Packet Length > 256 bytes

有代码例程吗?
