CANWrite id, data, 2, tx. Sets CAN baud rate. To be able to use the library effectively, you need to be familiar with these. This is a simple demonstration of CAN Library routines usage.

Filter registers are set according to flag value: CAN must be in mode in which receiving is possible. Instead, use this function when CAN is in Config mode. Datasneet to complexity of CAN protocol, you cannot simply force a bps value. If buffer is full, function returns 0. The greater distance the lower maximum bitrate that can be achieved.

18F datasheet & applicatoin notes – Datasheet Archive

There is a number of constants predefined in CAN library. Data transfer rates depends datasehet the distance. If at least one empty transmit buffer is found, function sends message on queue for transmission.

Function reads message from receive buffer. The second node responds by sending back the data incremented by 1. Copyright c mikroElektronika. Cables used are shielded twisted pairs.

It does not verify if CAN module is switched to requested mode or not.

The CAN is a very robust protocol that has error detection and signalization, self—checking and fault confinement. First node then does the same and sends incremented data back to second node, etc. CAN supports two message formats: Function sets message filter. Function sets mask for advanced filtering of messages. First node initiates the communication with the second node by sending some data to its address.


What do you think about this topic? If 0, this is a non-blocking call. Refer to datasheet for details.


If at least one full receive buffer is found, it is extracted and returned. Want more examples and libraries? Function returns current operational mode of CAN module.

Sets CAN to requested mode, i. Sets all mask registers to 0 to allow all messages. Faulty CAN data and remote frames are re-transmitted automatically, similar to the Ethernet.

Given value is bit adjusted to appropriate buffer mask registers. CAN must be in Config mode; otherwise the function will be ignored. You might want to check the example at the end of the chapter. CAN must be in Normal mode.
