Description: 对讲机在诸多行业领域广泛应用。虽然模拟对讲机现今仍垄断市场，但数字通信以其更丰富的业务种类，更好的业务质量、保密性和连接性，尤其可提高频谱效率，更有效利用宝贵的频谱资源，因此对讲机数字化是大势所趋。这里介绍一种基于CC1101射频器件的数字无线对讲机的语音通信技术。-Radio widely used in many industries. Although the current analog radio is still monopolizing the market, but a richer digital communications with its business lines, better service quality, security and connectivity, in particular, can improve the spectrum efficiency, more efficient use of valuable spectrum resources, it is the trend of digital radio . Here CC1101 RF devices based on digital wireless walkie-talkie voice communication technology.

Description: 开源一个SPEEX全双工数字对讲机。用NRF24L01实现了全双工通信，就像打电话一样，目前实现的只是点对点，直线距离测试最远有300M，用了网上那种加了PA的模块。电路采用STM32F103R作为主控制芯片。-Open source a SPEEX full duplex digital radio. With NRF24L01 achieve full-duplex communication, just like the phone, the only point-to-point realization of the current, straight-line test farthest 300M, with the kind of network that increases the PA module. STM32F103R circuit as the main control chip.
