| + | ===== Copyrights ===== | ||
| + | (c) [[http://www.merg.org.uk/|MERG]]\\ | ||
| + | |||
| + | ===== HEX ===== | ||
| + | This firmware needs a Rocrail [[:cbus-en#setup|CBUS Setup]] for serial and 230400 bps. (-0,79% tolerance: 228571 bps)\\ | ||
| + | Resonator: **8MHz**, Rocrail 2931+. | ||
| + | * http://launchpad.net/rocrail/sunrise/2.0/+download/canrs-230400-8mhz-bin-171.hex | ||
| + | |||
| + | ====Note==== | ||
| + | Most RS232 legacy ports cannot handle baud rates above 115200.\\ | ||
| + | To use the needed 230400 baud rate an **[[:usb-rs232-en|USB-232 converter]]** is the best solution.\\ | ||
| + | The CAN-GC1 can be equipped with an USB Sub-D type connector. | ||
| + | |||
| + | ===== Sources ===== | ||
| + | Compile with the "Case sensitive" option! | ||
| + | * https://github.com/rocrail/GCA/tree/master/cbus | ||
| + | \\ | ||
| + | |||
| + | =====Binary Response===== | ||
| + | The official CBUS protocol is in ASCII which doubles the number of bytes.\\ | ||
| + | To prevent frame loss the response from the CAN-GC1 to Rocrail has been made binary.\\ | ||
| + | An ASCII response starts with "**:S**" and a binary with "**:s**".\\ | ||
| + | |||
| + | ====Frame ASCII format==== | ||
| + | <code> | ||
| + | :ShhhhNd0d1d2d3d4d5d6d7d; :XhhhhhhhhNd0d1d2d3d4d5d6d7d; :ShhhhR; :SB020N; | ||
| + | :S -> S=Standard X=extended start CAN Frame | ||
| + | hhhh -> SIDH<bit7,6,5,4=Prio bit3,2,1,0=high 4 part of ID> SIDL<bit7,6,5=low 3 part of ID> | ||
| + | Nd -> N=normal R=RTR | ||
| + | 0d -> OPC 2 byte HEXA | ||
| + | 1d-7d -> data 2 byte HEXA | ||
| + | ; -> end of frame | ||
| + | </code> | ||
| + | |||
| + | ====Frame Binary format==== | ||
| + | <code> | ||
| + | :shhNd0d1d2d3d4d5d6d7d; | ||
| + | :s -> s=Standard start CAN Frame | ||
| + | hh -> SIDH<bit7,6,5,4=Prio bit3,2,1,0=high 4 part of ID> SIDL<bit7,6,5=low 3 part of ID> 2 bytes | ||
| + | Nd -> N=normal R=RTR 1 byte | ||
| + | 0d -> OPC 1 byte | ||
| + | 1d-7d -> data 1 byte | ||
| + | ; -> end of frame (should be a checksum in future versions) | ||
| + | </code> | ||
| + | Applications should read up to the OPC to determine the data length.\\ | ||
| + | |||
| + | |||
