CommandStation-EX/release_notes.md

The DCC-EX Team is pleased to release CommandStation-EX-v3.0.0 as a Production Release. This release is a major re-write of earlier versions. We've re-architected the code-base so that it can better handle new features going forward.

Known Bugs:

• Consisting through JMRI - currently does not work in this release. You may use the command to do this manually.
• Wi-Fi - works, but can be challenging to use if you want to switch between AP mode and STA station mode.
• Pololu Motor Shield - is supported with this release, but the user may have to play around with some timings to enable programming mode due to limitation in its current sensing circuitry

Summary of the key new features added to CommandStation-EX V3.0.7

• Support for 28 Speed steps - Option to turn on 28 step speed decoders in addition to 128. If set, all locos will use 28 steps.
• Improved overload messages with raw values (relative to offset)

Summary of the key new features added to CommandStation-EX V3.0.6

• Prevent compiler warning about deprecated B constants
• Fix Bug that did not let us transmit 5 byte sized packets - 5 Byte commands like PoM (programming on main) were not being sent correctly
• Huge function numbers (DCC BinaryStateControl) - Support Functions beyond F28
• <!> ESTOP all - New command to emergency stop all locos on the main track
• <- [cab]> estop and forget cab/all cabs - Stop and remove loco from the CS. Stops the repeating throttle messages
• <D RESET> command to reboot arduino
• Automatic sensor offset detect -
• Improved startup msgs from Motor Drivers (accuracy and auto sense factors) -
• Drop post-write verify - No need to double check CV writes. Writes are now even faster.
• Allow current sene pin set to UNUSED_PIN - No need to ground an unused analog current pin. Produce startup warning and callback -2 for prog track cmds.

Summary of the key new features added to CommandStation-EX V3.0.5

• Fix Fn Key startup with loco ID and fix state change for F16-28
• removed ethernet mac config and made it automatic
• fixed e/wifi port at 2560
• show wifi ip and port on lcd
• auto load config.example.h with warningh
• dropped example .ino files
• corrected .ino comments
• pololu fault pin handling
• waveform speed/simplicity improvements
• improved pin speed in waveform
• portability to nanoEvery and UnoWifiRev2 CPUs
• analog read speed improvements
• drop need for DIO2 library
• improved current check code
• linear command
• removed need for ArduinoTimers files
• removed
• Removed option to choose different timer
• Added EX-RAIL hooks for later
• fixed Turnout list
• allow command keywords in mixed case
• dropped unused memstream
• PWM pin accuracy if requirements met.

Summary of the key new features added to CommandStation-EX V3.0.4

• **"Drive-Away" Feature added so that throttles like Engine Driver can allow a loco to be programmed on a usable, electrically isolated programming track and then drive off onto the main track.
• WiFi Startup Fixes

Summary of the key new features added to CommandStation-EX V3.0.3

• command to write loco address and clear consist
• command will allow for consist address
• Startup commands implemented

Summary of the key new features added to CommandStation-EX V3.0.2:

• Create new output for current in mA for <c> command - New current response outputs current in mA, overlimit current, and maximum board capable current
• Simultaneously update JMRI to handle new current meter

Summary of the key new features added to CommandStation-EX V3.0.1:

• Add back fix for jitter
• Add Turnouts, Outputs and Sensors to <s> command output

Summary of the key new features added to CommandStation-EX V3.0.0:

• New USB Browser Based Throttle - WebThrottle-EX is a full front-end to controller to control the CS to run trains.
• WiFi Support - AP and station modes supported. Auto-detection of an ESP8266 WiFi module with AT firmware on a Mega's serial port. Connection to JMRI and WiThrottle clients.
• Withrottle Integrations - Act as a host for up to four WiThrottle clients concurrently.
• Add LCD/OLED support - OLED supported on Mega only
• Improved CV programming routines - checks for length of CV pulse, and breaks out of the wait state once it has received an ACK, now reading one CV per second.
• Improved current sensing - rewrote current sensing routines for safer operation. Current thresholds based on milliamps, not magic numbers
• Individual track power control - Ability to toggle power on either or both tracks, and to "JOIN" the tracks and make them output the same waveform for multiple power districts.
• Single or Dual-Pin PWM output - Allows control of H-bridges with PH/EN or dual PWM inputs
• New, simpler function command - <F> command allows setting functions based on their number, not based on a code as in <f>
• Function reminders - Function reminders are sent in addition to speed reminders
• Functions to F28 - All NMRA functions are now supported
• Filters and user functions - Ability to filter commands in the parser and execute custom code based on them. (ex: Redirect Turnout commands via NRF24)
• Diagnostic <D> commands - See documentation for a full list of new diagnostic commands
• Rewrote DCC++ Parser - more efficient operation, accepts multi-char input and uses less RAM
• Rewritten waveform generator - capable of using any pin for DCC waveform out, eliminating the need for jumpers
• Rewritten packet generator - Simplify and make smaller, remove idea of "registers" from original code
• Add free RAM messages - Free RAM messages are now printed whenever there is a decerase in available RAM
• Fix EEPROM bugs
• Number of locos discovery command - <#> command
• Support for more locomotives - 20 locomotives on an UNO and 50 an a Mega.
• Automatic slot managment - slot variable in throttle/function commands are ignored and slot management is taken care of automatically. <!> command added to release locos from memory.
