Appendix C. LIN Frames and Signals
This section describes LIN messaging with the frames, signals and the
LIN Stepper Controller functionality.
C.1 LIN Leveller Basic Frames
Figure C-1 describes the LIN Leveller signals and frames.
NOTE:
The LIN messaging scheme, with exact signal description and updated
according to latest software modifications, is described in the file
Messaging_LIN_Levellew.xls which is provided with the application
software files.
The signal provider is the node that sends the response fields
(
Section 9. References , 2 ) of the described frame. The signal acceptor
is the node that is programmed to act on the received frame (see
Section 4.1. Axis and Signal Providers and Acceptors ).
The column Signal Functionality Description describes the LIN
Stepper Controller functionality according to the described signal. The
raw value range is the range of the signal in system units. Although the
LIN API specifies the unsigned signals, some signals (e.g. position) have
signed representation. The normalized value is a physical
representation of the signal (variable).
NOTE:
The normalized value range is determined by the scaling factor. The
scaling constants RESOLUTION_FREQUENCY_HZ,
RESOLUTION_PERIOD_NS are defined and can be changed in the LIN
Stepper software header files.
See Sections 6.3.1 , 6.3.2 , 6.3.3 , and 6.3.4 for information about scaling.
