STM32如何将接收LIN总线数据
      各位大侠,大家端午安康!小弟最近初学LIN总线。现想将总线数据通过STM32的RX管脚进行接收,然后通过232显示在串口调试软件的窗口上。但一直未成功,可能是没有理解透LIN协议及TJA1028的用法。想请教下:     1、STM32 通过USART_IT_LBD进入中断后,接着是如何进行接收正常USART数据的(同步场、PID、数据)?中断函数该如何写?     2、从机接收帧

lin总线和UART的问题
最近要使用lin总线在PIC24F32KA304和PIC24FV32KA302的两块板子直接进行通信,前者为主板,后者为从板,使用的是TJA1020T收发器。在主板这,使用U2TX和U2RX,在从板这,使用U1RX和U1TX。 其中主板的LIN使能是RA8,从板的LIN使能是RA4。 下边是我试着写的一个程序。。。不能用。。。。。。。 求大神指点程序存在的问题,或者告知应该怎么设计程序。。。

LIN总线协议介绍与汽车电子中的应用zz
上世纪80年代,根据车用通信网络在不同控制层面的不同功能要求,SAE (Societv ofAuto-mobile Engineering)将其分为A,B,C三类。其中A类为低速网,数据传输速率通常为1~10kb/s,LIN总线通信网络就属于此类。LIN总线一般应用于不需要高性能及带宽和复杂性较大的低端系统,如车门控制模块、座椅调节、车灯控制和空调系统中传感器和执行器之间的通信。由于其LIN总

STM8关于LIN总线的请教
大家好!      小弟现在遇到一个奇怪的问题。      硬件测试环境:板子是STM8S208,板子上有两个LIN接口,一个做主机,一个做从机,用一条串口线将两个口连接起来通信。      问题:主机发送断开符和界定符,但是监测不到断开符检测标志位的变化,也就是断开符发送不成功。但是我确信主机有发送断开符,不过就是检测不到。      希望有这方面经验的朋友帮帮忙,小弟刚开始搞

TI 2803x DSP芯片LIN通信之波特率自适应
将SCIGCR1寄存器中的ADAPT位置1来使能波特率自适应功能,在帧头接收期间,从机节点利用同步场可以测量出波特率。SCI/BLIN同步器在帧头接收期间会确定两个计数器:BRK_count和BAUD_count。 LIN标准协议规定11个Tbit作为从机节点检测间隙场的门限值(间隙场至少为13个Tbit的显性)。在第五个连续的下降沿,BAUD_count可以被测量出,至此,从机节点
