RL-CAN library and receive mask

Briffaux Vincent

Hello everyone,

Question

I want my CAN to receive every message with ID 0x1000 to 0x1FFF, how can I do it ?

Ugly solution

NB: My CAN(s) can already receive messages with CAN_receive() by calling CAN_rx_object() with the correct ID.

U32 i = 0;

for (i = 0x1000; i < 0x1FFF; i++)
{
  CAN_rx_object(CAN_CTRL, CAN_CH, i, DATA_TYPE | EXTENDED_TYPE);
}
/* ... */

Is there something more elegant to do so ?

Best regards,

Vincent

    --> Device: LM3Sxxxx (LM3S9B96)
    -> We use STM32F103.

    Actually, you are talking about a completely different MCU, and a completely different CAN Controller.


    22 Controller area network (bxCAN)
    Low-density devicesare STM32F101xx, STM32F102xx and STM32F103xx
    microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.

    22.2 bxCAN main features
    Transmission: Three transmit mailboxes, Configurable transmit priority, Time Stamp on SOF transmission
    Reception: Two receive FIFOs with three stages, Scalable filter banks:
