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。
