3C28x eCAN Transmit
Purpose Configure an eCAN mailbox to transmit a message to the board’s CAN bus pins
Library c2800dspchiplib in Embedded Target for TI C2000 DSP
Description The C84x enhanced Control Area Network (eCAN) Transmit block generates
source code for transmitting eCAN messages through an eCAN mailbox. The
eCAN module on the DSP chip provides serial communication capability and
has 32 mailboxes configurable for receive or transmit. The C28x supports
eCAN data frames in standard or extended format.
Detailed information on the eCAN module is in the TMS320F28x DSP
Enhanced Control Area Network (eCAN) Reference Guide, Literature Number
SPRU074A, available at the Texas Instruments Web site.
Mailbox number — Unique number between 0 and 15 for standard or between
0 and 31 for enhanced CAN mode. It refers to a mailbox area in RAM. In
standard mode, the mailbox number determines priority.
Message identifier — Identifier of length 11 bits for standard frame size or
length 29 bits for extended frame size in decimal, binary, or hex. If in binary or
hex, use
bin2dec(' ') or hex2dec (' '), respectively, to convert the entry. The
message identifier is coded into a message that is sent to the CAN bus.
Message type — Select Standard (11-bit identifier) or Extended (29-bit
identifier).
