Software version history

• 

This article contains the MicroStar 2000 software version history. This data is a little cryptic because it was pulled from the MicroStar source code header and it is a history of all changes that have been made starting with the original version in 2001. You will also find a to do list defining future modifications that are planned.

 

; Revision History:
; All of the version 1.0 revesions were for the orginal Encoder design that had
; a final hardware revision of 3.0. Versions 2.0 are all designed for the hardware
; revision 4.0 and beyond. This revision uses the PIC 18F8722 PIC. The orginal
; encoder used a 17C766 PIC and the version 2.0 series is not compatable with that
; PIC.

; mixed to itself.
; 16.) Initial restructuring of the code for the MicroProStar and addition
; of the drivers. First release of the MicroProStar.

; I fliped it in this release.
; 18.) The MicroStar buddybox mode had a baudrate error.
; 19.) Updated the AUXOUT logic so that shift invert will change the PPM
; signal as it does the RF deck modulation pin.
; Version 2.0o, August 1, 2010
; 1.) Fixed a table numeric range bug, a rare issue that only happen at
; extreme stick and trim limits.

; maximums and 1100 and 1900 for the servo starting points
; 10.) Added a new ADC read mode for the MPS. This mode reads the joystick using
; the 5 volt ref and does battery voltage correct as well as insuring that
; the battery supply is stable.
; 11.) Fixed a mixer programming bug caused by the CalServoUpdate flag not being
; cleared on power up.
; 12.) Add canned output order, ACE = EART5678, Futaba = AETR5678,

; 2.) Add Move Mix function, also ask to clear the mixer we moved from.
; 3.) Add Apply to all option on a number of global functions, channel order
; 4.) Add a filter to the battery voltage monitor. Use a difference equation
; Vbat * N = Vbat(t-1) * (N - 1) + Vbat(t). Where N = filter time constant.
; This filter is scalled by 256 to prevent round off errors.
; 5.) Add a servo monitor display of position in percentage to allow transfer to
; mixer gain. Change all labels to three chars and add % to display.
; 6.) Fixed a bug on the mixers that only happens on throttle, CH5, or CH8 when
; mixed to itself.

; 2.) Added 12 internal channels.
; 3.) Added advanced mixer expresion capability.
; 4.) Update send serial to use the number of channel counter and add the 0xFF
; after the two SOT chars.
; 5.) Allow buadrate adgust for send serial
; 6.) Develope the dual rate digital trim
; 7.) Added microSD card interface with support for reading only at this time
;
; Version 2.0x, to do list
; B.) Fix the retract warning to work even without my RF deck and hold off the
; modulation signal.
; C.) Look into a minor display bug in the channel order options. The UI does
; reflect the currently select channel order.
; D.) Add the ability to control the servo positions from the PC
; application. Also add an API so a user can control with his own
; application.
; 1.) Add more aircraft specific tables, 7 total. Can't have more than 7
; aircraft tables. here is what needs to be done for this change:
; a.) Move the aircraft tables to the end of page 4 in the aircraft setup area.
; reserve the old space so we don't have to adjust pointers.
; b.) Add the 5 additional entries in the data.asm file
; c.) Edit the PC app to support the new tables and set defaults
; d.) Test this function
; 2.) and i just remembered another thing i don't find so user friendly:
; whenever i need to adjust something in one of the alternate aircraft
; memories i have to first call up and select that memory. with the new
; version's 6 alternates this could turn into a real nighmare. could it
; be changed so that whenever you switch to CAL mode you're automatically
; in the menu of whatever memory was currently being used and displayed on
; the LCD when the switch was hit?
; 3.) Allow no confirm of RF at startup. Do this by adding a EEPROM config function
; to the bootloader. Allow the following types of functions or at least consider
; these functions:
; a.) The no RF confirm option
; b.) Oversampling
; 4.) Trims carries across alternate aircraft. This should be optional and
; selectable trim by trim
; 5.) Have the transmitter broadcast the position information during adjustment
; of the table values.
; 6.) Digitial trim issues
; - The system doesn't seem to save to the *.CFG file the actual position
; of digital trims, and then, when loading the file using another MS2K
; radio, they are lost.;
; -When I set up an alternative aircraft and it happens to need a
; different trim position than the master has, that is, when I need
; different flight phases with different trimmings, digital trims do not
; act independently, but on all the phases at once.
; 7.) Allow auto trim to automatically go to trim zero thus more total range and
; no need to go to cal menus.
; 8.) Smooth transistion and timed when changing modes using alternate aircraft.
; 9.) Simplify the alternate aircraft setup options.
; 10.) Look at the CROW function and update it as per the MP8000
; 11.) Add switch functions to CH6 and CH7
;
