--uftEnKAyAqI9e0cowrGMV4nJ9gRxOBXf6doJ7lB Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit From your description, I am assuming you have buffer 1 filter open for all receptions. In that case you are seeing expected operation i.e. the CAN is capable of receiving its own transmissions. This is a feature of Toucan - on newer Flexcan implementations, you may disable self reception. The only way round this is to alter the filter to block the transmitted IDs if possible. - Allan ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Weer K Sent: Friday, April 11, 2008 10:07 AM To: [email protected] Subject: [MPC500] Question on CAN Hi, We are facing problems in CAN communication in MPC 565. We are using CAN_A for communication, I have configured Buffer 0 as transmitter and Buffer 1 as receiver. Rest all are configured as unused. We are seeing that whatever we are transmitting in buffer 0 is received in buffer 1. Please provide me some solution Regards, John __________________________________________________ Do You Yahoo!?
