The CAN is a very robust protocol that has error detection and signalization, self—checking and fault confinement. Faulty CAN data and remote frames are re-transmitted automatically, similar to the Ethernet.
Data transfer rates depends on the distance. The greater distance the lower maximum bitrate that can be achieved. Cables used are shielded twisted pairs. Sets CAN to requested mode, i.
Function returns current operational mode of CAN module. All pending transmissions are aborted. Sets all mask registers to 0 to allow all messages. CAN must be in Config mode; otherwise the function will be ignored. Sets CAN baud rate. Due to complexity of CAN protocol, you cannot simply force a bps value.

Instead, use this function when CAN is in Config mode. Refer to datasheet for details. Function sets mask for advanced filtering of messages. Given value is bit adjusted to appropriate buffer mask registers. Function sets message filter. Function reads message from receive buffer. If at least one full receive buffer is found, it is extracted and returned. If none found, function returns zero.
CAN must be in mode in which receiving is possible. If at least one empty daasheet buffer is found, function sends message on queue for transmission. If buffer is full, function returns 0. There is a number of constants predefined in CAN library. To be able to use the library effectively, you need to be familiar with these.

You might want to check the example at the end of the chapter. This is a simple demonstration of CAN Library routines usage. First node initiates the communication with the second node by sending some data to its address.
The second node responds by sending back the data incremented by 1. First node then does the same and sends incremented data back to second node, etc. CAN supports two message formats: Copy Code To Clipboard. Copyright c mikroElektronika. What do you think about this topic?
Want more examples and libraries? If 0, this is a non-blocking call.
It does not verify if CAN module is switched to requested mode or not. Filter registers are set according to flag value: Complement will do the trick and fill it up with ones. CAN must be in Normal mode. CANWrite id, data, 2, tx .
