| 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. |
| |
| What: /sys/bus/iio/devices/.../out_altvoltageX_frequencyY_scale |
| 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. |

| What: /sys/bus/iio/devices/.../out_altvoltageX_phaseY |
| KernelVersion: 2.6.37 |
| 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. |
| |
| What: /sys/bus/iio/devices/.../out_altvoltageX_phaseY_scale |
| KernelVersion: 2.6.37 |
| 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. |
| |
| What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_en |
| What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_frequency_en |
| What: /sys/bus/iio/devices/.../out_altvoltageX_pincontrol_phase_en |
| 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_out_enable |
| 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. |

| KernelVersion: 2.6.37 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Specifies the output waveform. |
| (sine, triangle, ramp, square, ...) |
| For a list of available output waveform options read |
| available_output_modes. |
