TM4C1294NCPDT: How to generate CAN interrupt using timers?

APOORV GARG

Part Number: TM4C1294NCPDT

Hi,

I wanted to develop an application with CAN interrupts and wanted to trigger that interrupt after few milliseconds using a timer for transmit and asynchronous event based interrupt for reception. However, I am not able to find any such provision in CAN controller.

Any help will be appriciated.

Regards,

Apoorv

    There is no direct connection between the timers and the CAN module (like there is for the ADC). You can configure a timer to give you an interrupt after some time period, or periodically, and then in the timer interrupt routine enable a CAN transmission. Creating an interrupt upon the reception of a CAN frame is more straight forward. You can see an example of this in the file: C:\ti\TivaWare_C_Series-2.1.4.178\examples\peripherals\can\simple_rx.c
