CAN transmit Interrupt

pooja jain c a

Hello,

Right now am developing CAN stack, where am trying to get TX_OK interrupt for every transmission but am getting that interrupt after transmitting all messages... So how is it ??? what i should do,to get interrupt after every transmission... am sure that i'll not object interrupt for every transmission...

Thank you,

Best Regards

Hello Pooja

Which TM4C12x device are you using? If you plot a GPIO toggle for TX_OK v/s the message transmitted on the scope, what does the image show in terms of the position of the TX)OK GPIO toggle viz-a-viz the messages.

Hai Amit Ashara,

Yeah am using TM4C123GXL Launchpad, CAN Stack am developing by using CAN drivers which is already available in TI source… am not using GPIO port pin…

Thank you,

Hello Pooja

Without source and corresponding LA/Scope capture, how would I be able to debug the issue you are seeing? What I have asked you to do is provide the scope/LA plot where one GPIO marks the messages being sent and another GPIO marks the interrupts.
