TMS570 CAN Communication question..

Other Parts Discussed in Thread: TMS570LS3137, HALCOGEN

I'm trying the can test of TMS570LS3137 Device.
Tx, Rx Interrupt method.
Tx Interrupt does not occur.
Does not call to the Interrupt routine.

I think, wrong setting value at CAN initialization.
please, review My Code. ㅡ.ㅜ;

Hello hwang,

Please refer to the example code explaining the set-up for Can communication using interrupts which comes along with Halcogen (example_canIntCommunication.c).

Hope that helps.

thank you..
yes, I'm trying test to example_canInitCommunication.
but TX Interrupt does not occur.
while(tx_done == 0){}; <- waiting (infinite loop)

CAN1 : Message Box1, id : 1, TX, (IF1)
CAN2 : Message Box2, id : 1, RX, (IF2)

use IF2 in canGetData() of can.c . so CAN2 is using MessageBox2.

define in order to test. (66 line from "#if 1" to "#if 0" in ht_can.c )
