TemperatureControlSystem
本系统严格按照题中所定参数及要求，构建了一个以MSP430单片机为控制核心的温度自动控制系统。该系统用PSB型负温热敏电阻作为温度传感器，以一种类R-F的方法测量木盒内实时温度，单片机用实时温度与预设温度值一起代入PID算式得出一个温度增量，再用此温度增量线性的控制PWM波的占空比，开关电源的输出电压也会随之变化，即制冷晶片的输入功率发生变化，因此制冷晶片制冷（加热）的功率随PWM波占空比变化，达到自动控温的目的。本系统制冷（加热）效果明显，效率高，界面友好，制作精致，能够胜任题中所定各项要求。(Question in strict accordance with the system parameters and requirements set out to construct a MSP430 microcontroller to control the core temperature control system. The system with the PSB-type negative thermal sensitive resistors as temperature sensors, the method in a class of RF real-time measurement of temperature inside the wooden box, single chip with real-time temperature and the preset temperature value into the PID formula come together on behalf of a temperature increase, then this temperature increment linear wave PWM duty cycle control, switching power supply output voltage will change, that is cooling the chip input power changes, so cooling the chip cooling (heating) power with the PWM duty cycle changes in wave to achieve the purpose of automatic temperature control. The system cooling (heating) effect is obvious, efficient, friendly interface, making sophisticated, capable of the requirements set out in the title.)

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。
