…eceived, otherwise the length of the packet this fixes reception of zero-length packets

Hi @mwensing, Please see the comment in #7 (comment) Maybe the examples should be updated accordingly? |
|
Of course fixing the examples is one way, but in my opinion the return value of the parsePacket function should differ between a packet with length 0 and no packet received at all. |
|
How can we achieve this also with the ReceiverCallback? |

Packets with DLC=0 are reported in the same way as if no packet has been received. As the CAN standard allows packets with DLC=0, I have changed the behaviour of parsePacket to return -1 if no packet has been received and the packet length otherwise.
