Syntax

transmitEvent(canch,msg,state)

Description

Examples

Enable an Event-Based Message

Configure a channel with an event-based message.

Construct a CAN channel and configure a message on the channel.

canch = canChannel('MathWorks','Virtual 1',1);
msg = canMessage(200,false,4);

Enable the message for event-based transmit, start the channel, and pack the message to trigger the event-based transmit.

transmitEvent(canch,msg,'On');
start(canch);
pack(msg,int32(1000),0,32,'LittleEndian')
