Hello, I was wondering if anyone could help to shed light on what creates the conditions that appear in the 'Compiler defines' field, under the build tab of application properties. They are created automatically every time I 'build' so I cannot just delete them from the text field. I'm trying to determine what causes them to appear, namely CANOPEN_NO_SYNC (highlighted below) and CANOPEN_NO_SYNCPDOS as this is leading to issues with CANOpen communications. I'm thinking it could be due to an incompatibility...
