Definition in file pic24_ecan.c.
| void clrRxFullFlagECAN1 | ( | uint8 | u8_bufNum | ) |
Clear full bit of buffer u8_bufNum
| u8_bufNum | buffer number of full bit to clear (0 to 31) |
Definition at line 115 of file pic24_ecan.c.
| void clrRxFullOvfFlagsECAN1 | ( | void | ) |
Operation: Clear all of the full and overflow RX flags.
Definition at line 143 of file pic24_ecan.c.

| ) |
Configure an acceptance Filter
| u8_filtNum | filter number (0 to 15) | |
| u32_id | identifier, either SID (11 bits) or EID (29 bits) | |
| u8_idType | ID type (0: SID, nonzero: EID) | |
| u8_bufnum | RX buffer (0-14) to use for filter , if 15, then use FIFO | |
| u8_maskReg | Mask register (0-2) to use for filter |
Definition at line 231 of file pic24_ecan.c.
Configure an acceptance MASK
| u8_maskNum | mask number (0 to 3; 0 to 2 specifies mask register, 3 then no mask is used) | |
| u32_idMask | mask for the identifier, either SID mask (11 bits) or EID mask (29 bits) | |
| u8_idType | ID type (0: SID, nonzero: EID) | |
| u8_matchType | Match type; if zero match either SID or EID addresses if filter matches (i.e, match if (Filter SID == Message SID) || (Filter SID:EID = Message SID:EID)) ) If nonzero, match only message types as specified by the filter (either SID or SID:EID). |
Definition at line 289 of file pic24_ecan.c.
Configure a buffer as either RX or TX buffer, only has to be done for first 8 buffers.
| u8_bufNum | buffer number (0 to 7) | |
| u8_type | buffer type (0 - receive, 1 transmit) | |
| u8_priority | only used for TX, priority (0-3) |
Definition at line 154 of file pic24_ecan.c.
