5.4.15 HRDLSetAnalogInChannel
int16_t HRDLSetAnalogInChannel
(
int16_t handle,
int16_t channel,
int16_t enabled,
int16_t range,
int16_t singleEnded
)
This function enables or disables the selected analog channel. If you wish to enable an
odd-numbered channel in differential mode, you must first make sure that its
corresponding even-numbered channel is disabled. (For example, to set channel 1 to
differential mode, first ensure that channel 2 is disabled).
Arguments
handle
Handle returned by
.
channel
The channel that will be enabled or disabled.
ADC-20: 1 to 8
ADC-24: 1 to 16
enabled
Sets the channel active or dormant.
0: dormant
<> 0: active
range
The voltage range to be used during sampling. Applies only to selected
channel. See
Voltage ranges
below.
singleEnded
Non-zero to measure a single-ended voltage.
Zero for a differential voltage.
Returns
0 if failed
1 if successful
If the function fails, call
with
info = HRDL_SETTINGS_ERROR (8)
to obtain the specific settings error.
