====== Ascent Control ======
===== How to customize the beep tone =====
Customizing the beep tone of the Ascent Vario is possible using the Ascent Control software.
  - Run Ascent Control
  - Connect Vario to PC
  - Select menu item Flght->User Settings...
  - Click "Read" button to read current settings
  - Modify settings to you desire
  - Click "Write" button to upload new settings to the Vario

==== Beep Parameters Explained ====
General Notes:
  - All values stored internally in the Ascent Vario are in metric.
  - Altitude data is in mm
  - Velocity data is in mm/s
  - If gap1_time_max is set to 0 then single beep mode, and only gap2 is used.
  - If gap1_time_max is not set to 0 then double beep mode, and only gap1 is the gap between the first and second beep.

=== Flags ===
=== Sink Alarm (mm) ===
velocity at with the sink alarm come on if the sink alarm flag is set.
=== Launch Detect Threshold (mm) ===
relative change in altitude from time fly mode has been entered required for launch detect
=== Vertical Speed Integration Time ===
time (in seconds) from which the current altitude is compared against to calculate the displayed velocity
=== Beep Sensitivity (mm/s) ===
minimum velocity that must be archived for audio lift alert to be played
=== Lowest Pitch (Hz) ===
frequency of audio lift alert at 0 mm/s lift
=== Highest Pitch (Hz) (velocity_tone_freq_min_Hz) ===
maximum frequency of audio lift alert
=== Pitch Scalar (velocity_tone_freq_scaler_mmps) ===
scaler used to calculate audio lift alert frequency as velocity changes
velocity_tone_freq_Hz = ( velocity / velocity_tone_freq_scaler_mmps) + velocity_tone_freq_min_Hz
=== Max Beep Time (ms) (beep_time_max) ===
maximum beep_time
=== Min Beep Time (ms) (beep_time_min) ===
minimum beep_time
=== Beep Time Scalar (beep_time_scaler) ===
=== Double Beep Max Gap (ms) ===
gap2_time_max
=== Double Beep Min Gap (ms) ===
gap2_time_min
=== Double Beep Gap Scalar ===
gap2_time_scaler
=== Beep Max Gap (ms) ===
gap1_time_max
=== Beep Min Gap (ms) ===
gap1_time_min
=== Beep Gap Scalar ===
gap1_time_scaler


  beep_time = beep_time_max - (velocity / beep_time_scaler)
  gap1_time = gap1_time_max - (velocity / gap1_time_scaler)
  gap2_time = gap2_time_max - (velocity / gap2_time_scaler)
