我对此也很陌生,所以如果我错了,希望有人能纠正我,我的理解是,缓冲区旨在与过滤器一起使用,以便特定的 ID 进入特定的缓冲区。 同时,FIFO 使用所有缓冲区并将任意 ID(或仅与配置的过滤器匹配的 ID)的消息排队。 当你从FIFO读出消息时,你会按照到达的顺序得到它们,但对于接收缓冲区来说,情况并非如此。 Like ...

Hi! I've been having some trouble getting the CAN (can0) RxFIFO working. Since I am not using the SDK (too much CPU load for my application) I

Hi, I have a project to make two boards communicate in CAN which using S32K144 & S32K146, and the following is my CAN config and driver. ///configextension_flexcan_rx_fifo_t can_fifo_ext0 = {.numIdFilters = FLEXCAN_RX_FIFO_ID_FILTERS_8,.idFormat = FLEXCAN_RX_FIFO_ID_FORMAT...
在S32K144 上,对于过滤表中超过 1 个 ID 元素,我无法让 CAN Rx FIFO 正常工作。我使用 R2022a 为 S32K144EVB (EVB) 创建了一个简单模型来演示该问题。在此模型中,CAN ...
Hi all: I have an STM32F407 and I am trying to implement a CAN bus software driver. I want to know if there has been a Rx FIFO overrun, which would
实际的 RX FIFO 结构包含8个字节用于标头信息、以及多达64个额外字节用于数据。 因此、如果 FIFO 配置为存储64字节的 CAN FD 消息、则 TCAN4550存储器中的实际 FIFO 元素将为72字节。 如果这一点很清楚、如果您还有其他问题、请告诉我。 此致、 Eric Schott...
On RX FIFO overrun, the ESP32 CAN controller delivers corrupted frames and false frame repetitions. Expected Behavior The ESP32 CAN controller is supposed to be SJA1000 compatible. We're operating it with driver code derived from the original CAN driver by Thomas Barth ...
The actual RX FIFO structure includes 8 bytes for the header information and up to 64 additional bytes for data. So if the FIFO is configured to store 64 byte CAN FD messages, the actual FIFO elements will be 72 bytes in the TCAN4550's memory. ...
