Both the CANUSB and CAN232 appear to the PC programmer as serial ports and are programmed by sending ASCII strings using standard codes ...
tiiildd...{CR} Transmit a standard (11bit) CAN frame where.
.......... iii is the message Identifier in hex (000-7FF) .......... l is the Data length (0-8) .......... dd the data byte values in hex (00-FF).
.......... So t1002AA33{CR} Sends an 11bit CAN frame with ID=0x100, and 2 bytes of data with the value 0xAA and 0x33
The CAN232 and CANUSB are almost completely program compatible. |
