I have the CAN functioning properly on the STM32F413 using Interrupts for Tx and Rx. I now want to add a response to an RTR message using the STM hardware only. I read the Ref Manual CAN chapter and the Datasheet. I understand how CAN functions and how to use the mask and list registers/FIFO's etc. What I believe I am missing is how to direct the ST hardware to auto-magically reply to an RTR without software intervention? Is there an app note or example I can use?
