汽车flexray总线驱动程序
应用背景随着现代汽车技术的发展,汽车安全性能要求越来越高,相应的电控单元和传感器数目大量增加,尤其是汽车线控(X-by-Wire)系统的增加,促进了汽车总线和网络技术的发展。传统的车载总线网络如CAN ( Controller AreaNetwork)、LIN (Local Interconnect Network)等由于自身的一些固有特点,在某些应用场合已经无法满足当前汽车安全性能和内外大量信息交换的需要,因此,新型的车载网络总线FlexRay应运而生。FlexRay协议由HexRay联盟开发,起初由BWM和DaimlerChrysler共同制定以满足他们当前以及将来的产品需求。随后就有 Bosch、NXP、Freescale、GM、Volkswagen 等公司加入,将 FlexRay协议不断完善并于2005年发表了 FlexRay协议V2.1版本。关键技术FlexRay节点软件主要是对MC9S12XF512 FlexRay通信控制器模块进行参数设置和初始化操作。由于FlexRay通信控制器本地时钟采用的是MC9S12XF512的内部时钟,所以在进行FlexRay模块初始化之前先要对MC9S12XF512的时钟锁相环PLL进行相关的配置。初始化MCU完成以后就使能MC9S12XF512 FlexRay模块并强制进入FlexRay协议状态配置启动FlexRay通信控制器。启动成功后查询HexRay节点是否同步到:FlexRay簇中,同步完成以后节点就 始正常的FlexRay收发工作。

This model is just testing an idea of MIMO, which IEEE802.11n
will have. But I havo not seen the standard, I tried to make
it with 11a. Actually this model would not work in real world,
because the preambles were not designed to solve the MIMO feature.
But this model may be useful to get some idea to start to
design a PHY with MIMO.
