I uploaded the “send” code from the wiki and hooked up the CANH and CANL to an oscilloscope. The shield seems to be sending data correctly but when I hook up the shield to CANalyzer I get some error and the software is not able to read what I am sending. Is the sample code only used to talk between two can bus shields or should I be able to use it to communicate to any can bus device? I also uploaded the “receive” code and used CANalyzer to send data. The interrupt flag never seems to be set and when I force it to be set, then there is no data on the bus (even though I know the data is there). If you have experienced similar problems I would appreciate any input you may have. Thank you!
