TransmitGlobalTime(传输时间戳使能):ENABLE/DISABLE 3.0.4、CAN验收筛选器 CAN网络上的所有节点没有地址的概念,因此当某个节点发送了特定ID的一条数据帧的时候,所有节点都会收到该帧消息,但是该帧应该只被需要接收该帧的节点接收,而其他不需要接收该数据帧的节点应该自动筛除掉该消息,减少资源浪费,那一个节点如何...
Priority: 当发生多个 DMA 通道请求时,就意味着有先后响应处理的顺序问题,这个就由仲裁器也管理。仲裁器管理 DMA 通道请求分为两个阶段。第一阶段属于软件阶段,可以在 DMA_CCRx 寄存器中设置,有 4 个等级:非常高、高、中和低四个优先级。第二阶段属于硬件阶段,如果两个或以上的 DMA 通道请求设置的优先级一样...
