Firmware Updates - V25
« on: 26 May 2017, 06:16 pm »
Starting a new Firmware Update topic (sticky)  for the V25 preamp controller board

We've gone through a couple of  firmware updates since original release of the V25 with initial version 1.0.0.3. 
Version 1.0.0.4 fixed a fairly egregious bug with the autocal logic which kept erasing old cal data.
Version 1.0.0.5 provides a more elegant way of turning preamp off via the remote
A few other minor bug fixes mixed in with those updates.

An updated firmware ChangeLog can be found in our new online Product Documentation
We're in the process of moving/updating our old Product Docs into this new system.

Version 1.0.0.6 firmware for the V25 is now available. This is mostly relevant to 2 or more V25 boards in a master-slave configuration including balanced audio systems. At this point the V25 is looking very solid and we are past the critical bug fix stage that's typical after the release of new hardware. The focus going forward will be on adding new planned capabilities.

How do you know what firmware version you have? The firmware version will flash briefly on the display when when power is applied (but not when you turn it on normally). 

Updated firmware and ChangeLog can be found in our new online Product Documentation

New - 2 way serial data link is now operational between master and slave boards so it's now ok to connect master J7.TX1 & J7.RX1 to slave board's J7.RX2 & J7.TX2 respectively. Prior to 1.0.0.6 making the connection to slave.J7.TX2 would cause master board to stop working properly. (relevant to multi-board/balanced configurations only)

Fix - Input switching via encoder was not getting through to attached slave boards. (relevant to multi-board/balanced configurations only).

Fix - All boards were defaulting to 6 available inputs regardless of how many inputs were actually installed and available. This remains the default for DIY V25 boards regardless of installed inputs but V25 boards installed in finished preamp products now have defined input # limit.

Version 1.0.0.7 firmware for the V25 is now available and can be found in our new online Product Documentation

Importance - This release fixes some minor bugs related to muting, volume limits and and changing inputs

Fix – Muting via Encoder press/release was immediately unmuting once volume ramped down to zero rather than staying at zero and remaining muted.

Fix – Max volume limiter on turn-on or input change was not limiting the volume to the user adjustable max limit value

Fix – When changing input the volume was not changing to the volume level last associated with the input when it was previously selected

Version 1.0.1.1 firmware for the V25 is now available and can be found in our new online Product Documentation

Importance - This update is only relevant if you want to use the Mono Switch feature

New – Added controls for Mono feature – double press Enter button toggles mono on/off. User must press enter button on remote 2 times in a row within 1 second to toggle mono mode. Requires presence of an LDR module in the V25’s mono switch socket. If this feature doesn’t work in your V25 preamp after uploading this firmware revision there’s about a 99.999% chance your preamp does not have a mono switch LDR installed.

Tweak – Minor mods to certain timer routines to improve overall operation

Version 1012  This update makes numerous changes to how adjustable impedance is handled. Info on this update can be found in the online documentation via this link:  https://www.tortugaaudio.com/support/product-documentation/
Go to section:  General Information -> Firmware Updates -> V25 Firmware

Importance  Release 1012 represents a major change to how adjustable impedance is handled. Upgrading to 1012 will cause your preamp to erase and reset all existing impedance settings and calibration data followed by automatically running calibration at the new fixed default of setting #1 @ 20k. The update will not be completed until this calibration step is completed. Please allow up to 15 minutes to allow the updating, reseting and calibration process to complete. The unit will reboot and restart after completion. Try not to turn of power or otherwise interrupt this process or else it will repeat from the beginning until allowed to fully complete.

Details
1) Impedance settings increased from 5 to 10.
2) Impedance setting #1 is now fixed at the default of 20k and can no longer be changed by user. Only settings 2-10 can be setup and modified by user.
3) The display will now blink when user selects an impedance setting number and level combination that has not already been run through calibration.
4) Switching the unit to any setting/level combination that is not calibrated will result in no output from the preamp.
5) Changing an impedance setting/level will not be saved or go into effect until after calibration is run. Press the Enter/Center button on remote after completing a change and then proceed to run calibration as the next step.  It's up to the user to ensure calibration is run as the final step. If calibration is not run immediately after making a setting/level change, the unit will revert to last known valid setting/level. If no other settings/levels have been configured the unit will revert to default #1/20k.
6) As before, each setting/level change must be done individually and then processed through calibration to become effective and/or available. User can not make multiple simultaneous changes to settings/levels and run them all through calibration together.

Version 1016 This update addresses a couple of changes in how responsive the Apple remote is to auto-repeat and also disambiguates (great word!) how to turn off the preamp with the remote.

Importance:  Minor improvements if operabiliity of controls

Details:
* Change (auto-repeat) - The faster Apple remote auto-repeat response introduced with 1014 has been slowed down for all buttons that can auto-repeat except for the Raise & Lower buttons.

* Change (turning off preamp) - The old way of turning off the preamp by press/holding the Menu button has been removed. The reason for this is the Menu button was serving two functions - toggling the mute status (brief press), and turning off the preamp (a longer press/hold). Too often this led to ambiguous results. Starting with 1016 the Menu button is now solely for muting/unmuting the preamp.

Turning off the preamp is now an unambiguous 2-step process:
1) Mute the preamp by briefly pressing the Menu(Mute) button
2) When the preamp is muted (volume @ 0), press the Lower button to turn it off.
