README for FREDi Release v2.4
===============================
The dmf file supports ALL FREDis, but requires the ATmega328P processor
Update with e.g JMRI - LocoNet Download Firmware feature
If update unsuccessful, retry update, and/or force re-run self-test by keeping E-stop pressed and hold for 10 sec while connecting to LocoNet.
Note: Running self-test will clear assigned loco
Disclaimer: Update goes normally without problems - but you never know... Update always on own risk!
RELEASE NOTES
=============
Release v2.4
* Analog vs Increment autodetect - PC5 solder bridge obsolete
* Break-FREDi new feature - Sail/Drive in software (using PC5 input), accounting for detecting direction switch while Sailing
* The above manifests as bit 4 in CV12 (HWCFG) - haveSailInp
* Direction LED slow blink while Sailing / direction switch in neutral (3-position dir switch)
Release v2.3
* Added feature: "All functions clear" - to acivate, keep ESTOP pressed 5 seconds
Release v2.2.2
* Fixed a problem with INC-FREDis randomly freezes
Release v2.2.1
* Need to turn to zero before able to undispatch
Release v2.2
* Support for BREAK-FREDi - break-button may be assigned any function F0-F19 (default F19)
* Support F13-F16, FREDi with two shift buttons (using both shift-buttons)
* Support config to enable OPC_IMM for functions above F9 (for backward compatible with legacy Command Station, e.g. DCS100)
* Improved e-stop handling when e-stop pressed when speed 0 (coasting)
* Improved inc-encoder handling around speed zero (one step hysteresis)
* Self-test ("factory reset") can be forced by press and hold e-stop for 10 sec while connecting to LocoNet
* Changed SV12 bit values
* Changed SV usage above SV24
Note:
* BREAK-FREDi, when running self-test, must have the break disable switch in OFF position (Break button active), otherwise the Break button not detected.
* SWD-FREDi, when running self-test, must have the direction invert switch in OFF position (normal direction), otherwise a BREAK-FREDi is detected.
Release v2.1
* Support F13-F16, Matrix (SWD) FREDi
* Improved Sail handling - FREDis with on-off-on direction switch
Release v2.0
* Support Matrix (SWD) FREDi
* Added Sail handling - on-off-on direction switch
Release v1.9
* Support F9-F12
