O_SET_LINE_LIMIT
:
This operate call allows the user to set the open loop
detect level on the current version of the SM-ADC1.
The syntax is as follows:
:= OPERATE(, O_SET_LINE_LIMIT,
);
where represents the analog return variable and can
be zero if the operate call is supported and the
correct is passed or non-zero if an
error occurred.
is the variable name for the channel where the
operate call is to take effect.
is the current value in mA and calculated using
the following formula:
var = 0xFFF0 mA
0x14
O_GET_LINE_STATE
:
This operate call allows the user to check the line
state on the current version of the SM-ADC1. The
syntax is as follows:
:= OPERATE(, O_GET_LINE_STATE,
);
where represents the analog return variable and is
zero if an open loop is detected. Otherwise it
returns 1.
is the variable name for the channel where the
