LIN Stepper Software Description
MOTOROLA
The other process’s states are controlled by functional calls from the
Slave Application control process and by dedicated variables. Variables
uAppFlags1
and
uAppErrFlags
reflect the system status and are set
and read by the three essential processes. The structure
sParameterRAM
includes the system parameters that determine the
application behavior. The components of the
sParameterRAM
structure
can be changed using parameter configuration (see
). Required position
positionReq
is derived from
l_u16_rd_positionReq
signal and is used for Position and Speed
control process. Similarly,
frequencyReq is
created from
l_u8_rd_frequencyReq
. Actual position
positionAct
from the Position
Sensing process is passed to the LIN message
l_u16_wr_positionAct
signal. Similarly, for
frequencyActLowHigh
and
l_u16_wr_frequencyAct
.
