Frame Format(帧格式):因为我们配置的是经典CAN模式,选择Classic mode,经典模式 Mode(模式):选择Normal mode,正常即可 Auto Retransmission与Transmit Pause:这两个都是FDCAN的特性 全部Disable就行 Protocol Exception(协议异常处理):这个打不打开都一样,打开可能有一点点好处,我这里选择了 Enable,关闭也无所谓 Nomina...
认识了CAN的Frame,再回到问题:“CAN L-PDU包含了些啥呢?”先看一下Autosar的解释:DataLink Layer Protocol Data Unit. Consists of Identifier, Data Length and Data (SDU). 解释:CAN L-PDU包含CAN ID、Data Length、Data,而这三个信息就是我们常说的HOH(Hardware Object Handle),HOH又进一步地细分HRH(Hard...
FrameFormat：配置传统can模式还是canfd模式，建议canfd，因为canfd兼容can模式(可以收发传统can报文)Auto...
1、CAN Frame格式 真正的解惑,需要先从CAN的格式(Frame)说起,参考11898 - 1,CAN的Frame可以分为如下几种: (一)Classical Base Frame Format 经典CAN基本格式如下所示: 其中:SOF Bit、IDE Bit、FDF Bit为常显性(logic 0)。 (二)FD Base Frame Format CAN FD的基本格式如下所示: 其中:SOF Bit、RSS Bit、...
FlexCAN 模块包括 CAN 收发器(CAN Transceiver)、协议引擎(Protocol Engine)、控制接口(Controller Host Interface)、总线接口单元(Bus Interface Unit),以及多个支持独立收发功能的信息缓冲区(Message Buffer)。其中 CAN 收发器负责将收发引脚的 TTL 信号转换为 CAN 总线的电平信号,协议引擎负责处理对信息缓冲区的读写...
Overload frame: a frame to inject a delay between data and/or remote frame. The RTR bit (Remote transmission request) determines between data frames (0) and remote frames (1) A CAN network can be configured to work with two different frame formats: the base frame format (CAN 2.0A & CA...

We offer a complete line of products to meet the needs of high-performance embedded applications using the CAN protocol, including 8-bit, 16-bit and 32-bit microcontrollers (MCUs), 32-bit microprocessors (MPUs) and Digital Signal Controllers (DSCs) with
On a button press from one node, nodes send the CAN frame to the other and vice versa; both the CAN FD nodes log the received data over the UART serial terminal. The user LED toggles each time a CAN FD frame is received. CAN FD frame format ID - CAN FD identifier DLC - Data ...
