Message Ram Offset(RAM消息地址偏移):范围0-2560,使用几个FDCAN就将2560平均分给几个,比如使用一个FDCAN1就填0,范围就是将RAM地消息0-2560分给FDCAN1。使用FDCAN1和FDCAN2,FDCAN1就填0,FDCAN2就填1280,FDCAN1范围就是0-1280,FDCAN2范围则是1281-2560。三个就以此类推
仲裁段配置参数和上面类似。 由于使用8脚的CAN phy 不涉及其他GPIO配置 4.点击CubeMX 生成代码 A、配置发送数据 FDCAN_TxHeaderTypeDef TxHeader; uint8_t TxData[8]= {0x30,0x55,0x34,0x39,0x23,0x22,0x11,0x28}; B、打开FDCAN if (HAL_FDCAN_Start(&hfdcan1) != HAL_OK) { Error_Handler()...

Std Filters Nbr(标准ID过滤数量) :这个参数的配置非常容易踩坑,它的参数作用是规定你需要过滤掉标准CANID的数量,通常我们我们不需要过滤任何ID,但这里绝对不能设置为0,如果设置为0则进入不了CAN的中断,必须设置为1即以上,设置为1也不代表我们需要在代码初始化过滤器时过滤掉一个ID,可将一个参数设置为0x00000000...
(4)Tx handler控制消息从CAN消息RAM到CAN内核。 (5)Rx handler控制CAN内核到CAN消息RAM。 91.2.2 CAN FD特性 (1)兼容经典CAN,可以遵循ISO 11898-1做数据收发。 (2)提升错误检测,支持高达CRC 21位的校验和。 (3)消息优先级。 (4)保证延迟时间。

SFF is computed from rates (approximate probabilities) of the different error classes and it is strongly dependent on DC, as can be seen from the equations below: SFF = (∑λS + ∑λDD) / (∑λS + ∑λD) DC = ∑λDD / ∑λD where: • ∑λS is the total rate of safe ...
