Due to complexity of CAN protocol, you cannot simply force a bps value. If at least one empty transmit buffer is found, function sends message on queue for transmission. If buffer is full, function returns 0.

The second node responds by sending datasheeg the data incremented by 1. CAN must be in mode in which receiving is possible. Data transfer rates depends on the distance. Function sets mask for advanced filtering of messages.

Faulty CAN data and remote frames are re-transmitted automatically, similar to the Ethernet. Cables used are shielded twisted pairs. You might want to check the example at the end of the chapter. Datssheet none found, function returns zero.

Function reads message from receive buffer. All pending transmissions are aborted. First node then does the same and sends incremented data back to second node, etc.

If at least one full receive buffer is found, it is extracted dstasheet returned. If 0, this is a non-blocking call. Sets all mask registers to 0 to allow all messages.

To be able to use the library effectively, you need to be familiar with these. Sets CAN baud rate.

The CAN is a very robust protocol that has error detection and signalization, self—checking and fault confinement. What do you think about this topic? It does not verify if CAN module is switched to requested mode or not.


CANWrite id, data, 2, tx. First node initiates the communication with the second node by sending some data to its address. CAN supports two message formats: Filter registers are set according to flag value: There is a number of constants predefined in CAN library.


Copy Code To Clipboard. This is a simple demonstration of CAN Library routines usage. Want more examples and libraries?

CAN must be in Config mode; otherwise the function will be ignored.

Given value is bit adjusted to appropriate buffer mask registers. Instead, use this function when CAN is in Config mode. CAN must be in Normal mode. Function sets message filter. Complement will do the trick and fill it up with ones. Function returns current operational mode of CAN module. Refer datassheet datasheet for details. Copyright c mikroElektronika. Sets CAN to requested mode, i. The greater distance the lower maximum bitrate that can be achieved.
