MX Foundation 4
Sending Messages

MX Foundation provides one mode of transmission to send CAN bytes on a given channel:

  • aperiodic transmission

Aperiodic Transmission is used to send a buffer of CAN bytes. The CAN bytes are sent to one of four priority queues. The precise timing when each CAN word transmission occurs can be defined using the time tag fields.

  • periodic transmission

Periodic Transmission is used to send CAN messages on a given channel with a specified update rate using the device onboard scheduler. The device scheduler performs the repetitive transmission. The buffer contents can be periodically updated by the host application. CAN messages are sent using the priority queue #1.

Error Injection can also be used to inject errors in transmission.

The channel must be configured as explained in the next section.


Configuring the channel

Before any transmission or reception takes place, the channels should be configured explicitly by setting the appropriates attributes. The channels attributes should always match the bus attributes.
