Syntax

CANGETINTS

 

 

Remarks

This statement is intended to be used in the CAN Interrupt routine. It will read the CAN interrupt registers and stores it into a word variable.

Multiple Message Objects can cause an interrupt at the same time. This means that all message objects need to be checked for a possible interrupt.

In the example this is done with a For Next loop.

 

Cangetints                                                                 ' read all the interrupts into variable _can_mobints                                          

For _can_int_idx = 0 To 14                               ' for all message objects
    If _can_mobints._can_int_idx = 1 Then               ' if this message caused an interrupt

        Canselpage _can_int_idx                             ' select message object
 

 

The loop checks all bits and if a message object interrupt has been set, the message object will be selected with CANSELPAGE.
