Cam and Crank - Cam Decoder v1
Cam and Crank - Cam Decoder v1 — The cam decoder
acquires a camshaft signal (generated from a cam encoder) and decodes the start
position and the camshaft tooth size.
Library
Simulink® Real-Time™ - Speedgoat
Description
The cam decoder acquires a camshaft signal (generated from a cam encoder) and
decodes the start position and the camshaft tooth size.
Ports
The Simulink block has two output ports:
Outputs
-
Cam tooth offset
Displays the cam tooth offset in degrees.
-
Cam tooth size
Displays the cam tooth size in degrees.
Parameters
Tab: Module setup
-
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.
-
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.
Tab: Cam Decoder
-
Crank master vector (read only)
The corresponding crank decoder master. This parameter is read-only,
and therefore only for information purpose. The crank decoder master is
predefined during the pin layout.
-
Number of teeth vector (read only)
This parameter defines the number of teeth defined in the crank
decoder master. This parameter is read-only, and therefor only for
information purpose. The number of teeth vector is defined in the crank
decoder mask.
