General information about CAN Send
With this CAN send block you can send a CAN message with a specified identifier on a specified CAN bus. Each time the block is evaluated, a message is send containing the input values.
Block
Mask
Parameter | Description |
---|---|
CAN channel | The CAN channel to be used, the E407 and P405 have two CAN channels, the Olimexino has only one. |
Identifier type | The type of message identifier to be used: either standard(11-bit) or extended(29-bit). |
Input ports | The number of input ports, the maximum number of bytes in a message is 8 so the maximum number of input ports is also 8. If for example uint16's are used you can only send 4 per message so you can select a maximum of 4 input ports per block. |
Input data type | The input data type to be used. This assumes all signals in a message have the same datatype. If this is not the case then just use uint8 and do the
processing of the bits and bytes in Simulink. |
Byte order | Byte order or endianness can be selected. If the checkbox is selected then the Most Significant Byte order, big-endian or Motorola order is used, if not then the Lease Significant Byte, little-endian or Intel order is used. |
Sample time | Sample time of the block. The Sample time (in seconds) defines the rate at which the block is visited by the real-time scheduler of the target. The value of the Sample time has to be an integer multiple of the base sample time of the model. |
