How to Transmit and Receive with CAN ID 0x000
The CAN Component Transmit Buffer and Receive Buffer support CAN ID from 0x001 to 0x7FE . My application needs to transmit and recieve with the CAN ID 0x000. How do I do it ?
<b>Transmit with ID 0x000</b>
The CAN Configuration Window in the Creator does not allow you to set the ID 0x000. You need to write directly to the CAN ID Register to send with ID 0x000. Below is the syntax.
The Message_No corresponds to the Mailbox Number. Id corresponds to the IDE which in your case will be 0x000.
<b>Receive with D 0x000</b>
To receive message only from the ID 0x000, the AMR and ACR value should be
Use the below syntax
/* Sets the AMR value for RX buffer 0 */
/* Sets the ACR value for RX buffer 0 */
CAN_RXRegisterInit((uint32)CAN_CanIP__RX0_ACR, 0x00000000 );
