Is there a way to set the CAN ID from software rather than via Configuration from schematic.

Jump to solution

I need to dynamically configure the CAN controller ID at init time via software. Not able to see an API call that does this.

Thanks!

Yes, you can use CAN_TxBufConfig() or/and CAN_RxBufConfig() functions. For more details see component datasheet and how they are used in can.c (in CAN_RxTxBuffersConfig() function) file from Generated_Source.

Hi dodo_4647966​,

In addition to LiDo_2439176 points, we believe what you are looking for is a basic mail box. Please refer to CAN_Basic_P4_Example and CAN_Full_P4_Example code example. PSoC Creator > File > Code Example
