-  * **pin**: ''Output'' GPIO ''pin'' number. +  * **freqBase**: Starting pulse frequency in pulses per second. 
-  * **freqBase**: Starting pulse frequency in pulses per second (20 to 3300). +  * **freqTop**: Final pulse frequency after acceleration.
-  * **freqTop**: Final pulse frequency after acceleration (20 to 3300).+
   * **freqAccel**: Acceleration rate in pulses per second per second. Must be > 0 when ''freqBase'' < ''freqTop''.   * **freqAccel**: Acceleration rate in pulses per second per second. Must be > 0 when ''freqBase'' < ''freqTop''.
