8.3.5 Transmitting a Standard CAN Frame
Transmitting a standard CAN frame (ID: 11 bit) over a CAN bus can be done with the
command tiiildddd…dd[CR]. The return value will be z[CR] or the normal error byte
(BELL). The command is only available when the CAN bus channel is open.
Command
Response
Function
tiiildddd…dd[CR] z[CR]
Transmits a standard CAN message (11 bit) over
the CAN bus
iii: Standard CAN frame (11 bit) identifier in hexadecimal format (000-7FF).
l: CAN data length (0-8) DLC, with the maximum value being 8 (8 bytes).
dd: Data byte value in hexadecimal format (00-FF). The number of bytes must be equal
to the data length field.
Example: t00231199FF[CR] will send a standard CAN frame with ID = 002h, DLC = 3,
Data = 11 99 FF.
8.3.6 Transmitting a Standard Remote Request CAN Frame
Transmitting a standard remote request CAN frame (ID: 11 bit) over a CAN bus can be
done with the command riiil[CR]. The return value will be z[CR] or the normal error
byte (BELL). The command is only available when the CAN bus channel is open.
Command
Response
Function
riiil[CR] z[CR]
Transmits a standard remote request (11 bit) over
the CAN bus
iii: Standard remote request CAN frame (11 bit) identifier in hexadecimal format (000-
7FF).
l: CAN data length to request (0-8) DLC, with the maximum value being 8 (8 bytes).
Example: r0023[CR] will send a standard remote request CAN frame with ID = 002h,
DLC = 3 and request 3 data bytes.
