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。

645-485
一个电表行业专用的基于645规约的电表485通讯抄表程序,可以进行485总线抄表,645规约测试。程序技术要点就是规约数据传输协议的处理,如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)
