Serial - Read Frame v1
Serial - Read Frame v1 — The Serial Read HW FIFO
driver block allows a complete Frame to be read from an Serial
Transceiver
Library
Simulink Real-Time - Speedgoat
Description
The Serial Read Frame v1 driver block allows to buffer incoming bytes and then
outputs data when a frame has been detected.
Ports
Inputs
-
enable
A global switch which enables (1) or disables (0) the read operation.
Outputs
-
data
A vector of 129 elements which represents the Serial HW FIFO. First
element of this vector indicates how many bytes have been read from the
FIFO. Subsequent elements form the data.
-
online
A boolean which indicates if the read block detected a header byte.
Its value returns to false in case the header detection fails during
runtime.
Parameters
-
Configurable I/O Module ID
This parameter associates a code module block with a configurable I/O module setup
block. Set this value to match the Module ID defined in the setup block of the
required configurable I/O module.
-
Channel Vector
A vector of channels this driver block entity will access. You can specify
channels in the range 1-N (N = the number of channels implemented in your specific
configuration file defined in the Setup block). The width of this vector also
defines the subsequent size of some of the following parameters if scalar expansion
applies. With a single block, all the channels of the block are synchronized.
-
Header byte value
A scalar defines the header this driver block entity will track in the
bytes stream.
-
Frame size
Defines the expected frame size. The block checks if the header is
present at the beginning of every frame.
-
Sample Time
Defines the base sample time at which this driver block gets its sample hit. This
parameter can also be set to -1 for inherited
sample time. The units are in seconds.
