What: /sys/bus/iio/devices/.../out_altvoltageX_frequencyY
|
KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
Stores frequency into tuning word Y.
|
There will be more than one out_altvoltageX_frequencyY file,
|
which allows for pin controlled FSK Frequency Shift Keying
|
(out_altvoltageX_pincontrol_frequency_en is active) or the user
|
can control the desired active tuning word by writing Y to the
|
out_altvoltageX_frequencysymbol file.

|
KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
Scale to be applied to out_altvoltageX_frequencyY in order to
|
obtain the desired value in Hz. If shared across all frequency
|
registers Y is not present. It is also possible X is not present
|
if shared across all channels.

What: /sys/bus/iio/devices/.../out_altvoltageX_frequencysymbol
|
KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
Specifies the active output frequency tuning word. The value
|
corresponds to the Y in out_altvoltageX_frequencyY.
|
To exit this mode the user can write
|
out_altvoltageX_pincontrol_frequency_en or
|
out_altvoltageX_out_enable file.

Contact: linux-iio@vger.kernel.org
|
Description:
|
Stores phase into Y.
|
There will be more than one out_altvoltageX_phaseY file, which
|
allows for pin controlled PSK Phase Shift Keying
|
(out_altvoltageX_pincontrol_phase_en is active) or the user can
|
control the desired phase Y which is added to the phase
|
accumulator output by writing Y to the phase_en file.

Contact: linux-iio@vger.kernel.org
|
Description:
|
Scale to be applied to out_altvoltageX_phaseY in order to obtain
|
the desired value in rad. If shared across all phase registers
|
Y is not present. It is also possible X is not present if
|
shared across all channels.

What: /sys/bus/iio/devices/.../out_altvoltageX_phasesymbol
|
KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
Specifies the active phase Y which is added to the phase
|
accumulator output. The value corresponds to the Y in
|
out_altvoltageX_phaseY. To exit this mode the user can write
|
out_altvoltageX_pincontrol_phase_en or disable file.

KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
out_altvoltageX_pincontrol_en: Both, the active frequency and
|
phase is controlled by the respective phase and frequency
|
control inputs. In case the device in features independent
|
controls, then there are dedicated files
|
(out_altvoltageX_pincontrol_frequency_en,
|
out_altvoltageX_pincontrol_phase_en).

What: /sys/bus/iio/devices/.../out_altvoltageX_outY_enable
|
KernelVersion: 2.6.37
|
Contact: linux-iio@vger.kernel.org
|
Description:
|
out_altvoltageX_outY_enable controls signal generation on
|
output Y of channel X. Y may be suppressed if all channels are
|
controlled together.
