Due to complexity of CAN protocol, you cannot simply force a bps value. If 0, this is a non-blocking call.

Filter registers are set according to flag value: You might want to check the example at the end of the chapter. Function returns current operational mode of CAN module. The second node responds by sending back the data incremented by 1. Copyright c mikroElektronika.

Cables used are shielded twisted pairs. Function sets mask for advanced filtering of messages. Sets all mask registers to 0 to allow datashet messages. Instead, use this function when CAN is in Config mode. If buffer is full, function returns 0. Sets CAN to requested mode, i.


What do you think about this topic? CAN must be in mode in which 182f480 is possible. The CAN is a very robust protocol that has error detection and signalization, self—checking and fault confinement.

This is a simple demonstration of CAN Library routines usage. First node then does the same and sends incremented data back to second node, etc. All pending transmissions are aborted.


CAN must be dataseet Config mode; otherwise the function will be ignored. If at least one empty transmit buffer is found, function sends message on queue for transmission.

CANWrite id, data, 2, tx. Data transfer rates depends on the distance. Sets CAN baud rate. Function reads message from receive buffer.

Want more examples and libraries? If none found, function returns zero. Copy Code To Clipboard. First node initiates the communication with the second node by sending some data to its address.

Refer to datasheet for details. There is a number of constants predefined in CAN library.


Given value is bit adjusted to appropriate buffer mask registers. CAN must be in Normal mode. Complement will do the trick and fill it up with ones. Function sets message filter.

It does not verify if CAN module is switched to requested mode or not. To be able to use the library effectively, you need to be familiar with these. Faulty CAN data and remote frames are re-transmitted automatically, similar to the Datazheet. The greater distance the lower maximum bitrate that can be achieved. CAN supports two message formats: If at least one full receive buffer is found, it is extracted and returned.
