Prototype | char CANSPIRead(long *id, char *data, char *datalen, char |
| *CAN_RX_MSG_FLAGS); |
|
|
Returns | Message from receive buffer or zero if no message found. |
|
|
Description | 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. |
| Parameters: id is message identifier; data is an array of bytes up to 8 bytes in length; |
| datalen is data length, from |
| (see CAN constants). |
|
|
Requires | CANSPI must be in mode in which receiving is possible. |
|
|
Example | char rcv, rx, len, data[8]; long id; |
| rcv = CANSPIRead(id, data, len, 0); |
|
|
Prototype | char CANSPIWrite(long id, char *data, char datalen, char |
| CAN_TX_MSG_FLAGS); |
|
|
Returns | Returns zero if message cannot be queued (buffer full). |
|
|
Description | If at least one empty transmit buffer is found, function sends message on queue for |
| transmission. If buffer is full, function returns 0. |
| Parameters: id is CANSPI message identifier. Only 11 or 29 bits may be used depend- |
| ing on message type (standard or extended); data is array of bytes up to 8 bytes in |
| length; datalen is data length from |
| constants (see CAN constants). |
|
|
Requires | CANSPI must be in Normal mode. |
|
|
Example | char tx, data; long id; |
| tx = CAN_TX_PRIORITY_0 & CAN_TX_XTD_FRAME; |
| CANSPIWrite(id, data, 2, tx); |
