CC1101Schematic-experimental-code
MSP430g2553实现CC1101无线通讯。
最近有个项目,使用CC1101无线传输控制,刚开始做使用MEGA8实现,当晚也没有考虑功耗的问题,但最后项目要求用电池供电,这就出现问题了。无线在发射时的系统的整个功耗在16ma左右,这样一算,不论实用什么电池也不能实现一个月的工作时间。但是要实现,就要一步一步的调试。第一部做的是把MEGA8的供电降到3.3V, 这样的系统的功耗能够降低一半,但是总的时间还是不能实现;第二部把系统的DC/DC稳压片替换成低电流输出、低功耗的稳压电源。这样两步下来,系统功耗降到8ma,可惜的还是不能实现。再进一步,让无线间隔性工作,工作30S,停30S。这样功耗又进一步下降,但是用电池供电的话,只能维持10天左右,要想实现30天,不太可能啊。
CC1101原理图实验代码
拿到LaunchPad后,第一想到是将代码移植到上面,看看系统的功耗。今天上午很容易移植成功了,一没功耗,让我看到了希望,在没有采取任何降低功耗的措施下,系统的功耗是4ma,无线一直在工作状态。太好,如果采取功耗设计,我想一定能够实现项目要求,期待能够调试出更低的功耗。
