与802.3ah协议中不同的是,802.3av协议采用了纠错性能更佳的Reed-Solomon(255,223)码作为信道码,以保证物理层与数据链路层接口数据误码率低于10-12。 RS译码器的设计因关键方程求解KES(Key Equation Solution)电路所采用算法不同而分为两种,分别是基于BM(Berlekamp-Massey)算法以及ME(Modified Euclidean)算法[2]。由...

STM32单片机的IO都是CMOS电平,所以理应使用MAX3485芯片。如果一定要做TTL和CMOS的电平转换,记住CMOS可以驱动TTL,而TTL驱动CMOS时需要上拉电阻。如果电平搞错了,最明显的状况就是发送正常而接收乱码。 RS485的终端电阻不要乱接。RS485的终端电阻是接在总线最末端防止电波反射的,如果线很短干脆就不要接了,否则反而容...
