Release: 3.12b1                                                      2018-07-20


(1) 5885 - 3.1/3.11 experience communications problems with the Setup Utility

    Frequent communication timeout problems on can occur between Cycle Analysts
    running firmware versions 3.1 or 3.11 and the Setup Utility running on
    certain PC platforms.  The difficulties occur when either 3.1 or 3.11
    firmware is already loaded and one of the following Setup Utility operations
    are attempted:
    
	a. doing an 'Update Firmware' - either the program flash does not start
	   or the last step updating the setup fails -OR-
	b. doing 'Read CA' or 'Write CA' operations to display/modify the CA
	setup
    
    In either case the CA typically hangs showing "PC Connection..." and the
    Setup Utility reports a timeout error.
    
    CA serial comms programming has been revised to better provide timely
    communication with Setup Utility.

    This is an internal change with no CA setup or setup file consequences.

Release: 3.11                                                      2018-07-19


This production release of Cycle Analyst firmware remedies issues in the
original 3.1 release as well as providing other improvements.  It should in all
cases be installed in place of the original 3.1 production release.

Changes are listed below for intermediate beta versions.

Release: 3.11b3                                                      2018-06-21


(1) 5781 - Battery 'Hot Swap' screen shows 0V and corrupted special characters

    The transient Battery 'Hot Swap' screen shows the nominal pack volatge as
    zero.  Other non-ASCII custom characters on the screen are corrupted.

    Proper display of this screen has been restored.

    This is a display change with no CA setup or setup file consequences.


(2) 5785 - (new) improve PAS startup performance for crank bikes

    For bikes other than rowbikes, version 3.1 implemented a conversative
    strategy to detect when pedaling starts and assist begins.  This aspect of
    PAS relates to the degree of crank rotation and is distinct from cadence
    detection controlled by the Start and Stop Thresholds
    
    A less conservative strategy has been implemented so that PAS is (re)applied
    more briskly from a standing start or when pedaling resumes while underway.
    This gives most noticeable benefit when the PAS sensor has few poles
    (magnets).
    
    This is an operational enhancement with no CA setup or setup file
    compatibility consequences.

Release: 3.11b2                                                      2018-06-05


(1) 5575 - Browsing Console Setup Aux Analog menu causes settings to be corrupted

    Traversing 'Lo/Hi Deadband' or 'Switch Lo/Med Level' settings of the AuxA
    menu in Console Setup causes the PAS device to change to 'Disabled' or other
    settings to be unintentionally altered. Other unintended setup changes might
    also occur on the next power-up causing a 'Setup Changed!' message to appear.

    This issue has been corrected.

    Setup files read from the CA under version 3.1 may contain errors and should
    be rebuilt or visually checked in the Setup Utility or CA Console. There are
    no compatibility issues with setup files produced in prior versions.


(2) 5547 - Speedometer reads improperly over 45mph (72kph)

    The speedometer debounce logic limits accurate speed display to a specific
    maximum (only) for pole counts of 1, 2, or 3.  In 3.0x firmware this maximum
    speed was approximately 90mph (145kph), however, 3.1 firmware reduces that
    limit to only 45mph (72kph).  Many ebikes can exceed this limit resulting in
    improper speed display.
 
    The original limit of 90mph (145kph) has been restored.

    This is an operational issue with no CA setup or setup file consequences.


(3) 5617 - Aux Change PAS Power indication displays 'true power'/10 in Hi Range

    Actual applied PAS power is correct, but in Hi Range the AuxChange display
    is 1/10 the true value.
 
    The Aux Change PAS power display is now multiplied by 10 to show the correct
    value to the nearest 10 watts.

    This is a display issue with no CA setup or setup file consequences.

    
(4) 5427 - Setup Utility sometimes fails to communicate with CA

    The Setup Utility occasionally fails to read/write CA settings or to update
    firmware.  An issue with CA processing of communication messages has been
    identified and repaired.

    This is related only to communication using the programming cable and does
    not affect CA settings or setup files.


(5) 5369 - Help files don't have link in category index to battery setup menu

    A proper hyperlink to the referenced Battery Category has been added to the
    Setting Summary Help file "2.0 Category Index".

    This is a documentation change with no CA setup or setup file consequences.


(6) 2020 - The 'Miscellaneous' Setup category identifies settings using 'Pref'

    The earlier 'Preferences' 3.0x category was split into 'Disp' and 'Misc' in
    3.1.  Settings in CA Console setup continue to use the 'Pref' designation.

    This labeling has been corrected.

    This is a display change with no CA setup or setup file consequences.


(7) 5539 - Setup 'Disp' Category Preview Screen shows 'Misc->DspAvging'

    The reorganization from the Preferences' to 'Display' and 'Misc' categories
    left the CA Console Setup erroneously showing the 'Display Averaging'
    setting on the display category preview screen.

    The Display Preview screen has been revised to show the selected Custom
    Views in place of the previous content.

    This is a display change with no CA setup or setup file consequences.


(8) 2020 - Navigation arrows in Setup MISC category are incorrect

    The submenu navigation arrows in the MISC category have been corrected to
    properly show the first and last menu items.

    This is an operational issue with no CA setup or setup file consequences.


(9) 5699 - Negative PAS Start Level does not work correctly

    Both PAS Start level and Scale Factor can be specified as signed numbers,
    however negative Start Levels were previously treated as zero in Basic(Pwr)
    mode.

    Proper handling has been implemented allowing an initial negative power
    assist to postpone PAS assist until the cadence power contribution exceeds
    the initial negative power level.
    
    This is an operational issue with no CA setup or setup file consequences.


(10) 4982 - (new) Improve PAS start/Stop sensitivity

    PAS Start/Stop sensitivity is related to the time between pulses from the
    PAS sensor.  PAS sensors with more magnets have to rotate less to create
    faster pulse streams. The PAS firmware has been revised to effectively
    double the pulse rate allowing the CA to detect crank motion much sooner.
    This enhancement works for all PAS modes and devices including rowbikes.

    An accompanying change has been made to PAS->StrtThrsh and PAS->StopThrsh
    default values to reduce sensitivity to slow pedal motion (e.g. PAS starts
    too soon, stops too late). This issue may present after upgrading the
    firmware and inheriting settings from the previous version (i.e. upgrading
    without loading defaults). If so, reset the PAS Start/Stop thresholds to the
    new defaults (Start, Stop) = (0.30, 0.19) or reduce custom setting values by
    about one third.

    This is an operational enhancement with no CA setup or setup file
    compatibility consequences.


(11) 5543 - (new) Change default PAS Start Levels for various modes

    The default PAS Start Levels are lower than might typically be useful and
    require adjustment, defeating the out-0f0box operation idea of default
    values.  The power levels have been adjusted upward to:

	Basic (Pwr) = 500 Watts
	Basic (ThO) = 50% throttle
	Torque      = 62 Human Watts

    This is an operational enhancement with no CA setup or setup file
    compatibility consequences.  The new defaults appear on a fresh firmware
    flash or when PAS->PASMode is altered.


(12) 5092 - (new) Reduce maximum pole count to 30

    The previous v3.1 maximum pole count of 60 has been reduced to 30 to
    conserve memory resources.  The previous value accommodated a limited number
    of unusual motor and gearing configurations that can be addressed indirectly
    with a lower pole count by making a corresponding alteration to wheel
    circumference.
