Function Library 241
_8164_set_trigger_type
:
Sets the trigger output mode
In hardware version A2, it is used for setting the output pulse as a
one shot or constant on.
In hardware version A3, it is used for setting the output pulse as
normal high or normal low.
_8164_check_compare_data
:
Obtains the current comparing data of the designated comparator.
_8164_check_compare_status
:
Obtains the status of all comparators. When some comparators
come into existence, the relative bits of cmp_sts will become ‘1,’
otherwise
0 .
_8164_set_auto_compare
:
Sets the comparing data source of the trigger comparator. The
source can be either a function or a table.
_8164_build_compare_function
:
Builds a comparing function by defining the start/end point and
interval. There is no limitation on the max number of comparing
data. It automatically loads a final point after user’s end point. That
is, (end point + Interval x total points) x move ratio.
Note: Turn off all interrupt functions when triggering is running.
_8164_build_compare_table
:
Builds a comparing table by defining a data array. The size of
array is limited to 1024 when using RAM mode.
Note: Turn off all interrupt functions when triggering is running.
_8164_cmp_v_change
:
Sets up the comparator velocity change function. It is a v_change
function but acts when a general comparator comes into exist-
ence. When this function is issued, the parameter “CmpAction” of
_8164_set_general_comparator()
must be set to 3 which is
for speed change option.
