Re: Receiving CAN messages with TouCAN

Thank you for your help,

now I'm using a workaround: The application listens with one buffer for
all events. If it reads something interesting, a buffer is configurated
for the according identifier. This works quite fine and I ain't miss any
important messages. (Of course I have to set the read cycle time
correctly to the shorted period of a message.)
