Using a PCAN VIEW, I determined the "rudder position" address (Yamaha Outboard), to be 166792448, and using CAN_Rx_MessageProc_ST_0 got the outboard position from bytes 4 and 5 of the 8 byte array:
RUDDER_ANGLE_RAW := WORD_TO_INT((256*MESSAGE_RX_NMEA[5]) + MESSAGE_RX_NMEA[4]);
I assumed that this Address would stay constant, but when the outboard changed, the address also changed - new address was 166792453. And further to this, after a power cycle, the address changed again to 166792456.
Assuming this has to do with address claiming, conflict, and the address changing.
The questions I have (and I have tried to grasp concepts but as a newby here am struggling) are thus:
1 Is there a range within in which this address will stay?
2 Can I get information out of the 8 byte received data (such as "yamaha outboard" or manufacturer specific info) that I could use to determine what the actual address is?
IF there is a range, I could write a procedure to scan the range, looking for the manufacturer ID, and thus determine the correct address.
Any help appreciated would be appreciated!
