RN8209计量芯片通讯读写程序，已经使用于单相电量表中(RN8209)

本源码程序为射频通信驱动代码，采用IAR system软件开发，以MSP430单片机为主控芯片，程序集成了CC1120，CC1200，CC1101等多种射频芯片，在使用时可通过用户自己屏蔽不需要的芯片，程序中均已文件分好，各种芯片的代码互不干扰。我已经通过测试，改程序可以直接运行，但用户在使用时需进行IAR软件的路径配置(The source program for RF communication driver code, using the IAR system software development, MSP430 single chip as the main control chip, the program integrates CC1120, CC1200, CC1101 and other radio frequency chip, by the users themselves do not shield chip when in use, the program have the good, various chip code do not interfere with each other. I have passed the test, reform program can be run directly, but the path to configure user required when using IAR software )

MICRO 830 AND 4M DRIVE MODBUS COMMUNICATION

The book focuses very much on impulse radio UWB techniques rather than multiband systems. The reasons for this are both practical and historical. The promise of UWB was low complexity, low power and low cost. Impulse radio, being a baseband technology, holds the most promise to achieve these three benefits.
