RFM12B and AVR The RFM12B tranceiver module has become quite popular recently due to its low price comparing to other modules on the market. But many people nd it hard to make these tranceivers work (mainly because of buggy programming guide provided by manufacturer, I guess...). This short article contains compact and simple code that can be used just to get these modules running for the rst time. It is based on manufacturer s examle code with slight (but crucial) changes.

串口通信的实现 -serial communications to achieve!

利用哈夫曼编码进行通信可以大大提高通信信道利用率，缩短信息传输时间，降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码；在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双工传输信息的信道），每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.
