The DCC-EX Team is pleased to release CommandStation-EX-v3.1.0 as a Production Release. Release v3.1.0 is a minor release that adds additional features and fixes a number of bugs. With the number of new features, this could have easily been a major release. The team is continually improving the architecture of DCC++EX to make it more flexible and optimizing the code so as to get more performance from the Arduino microprocessors. This release includes all of the Point Releases from v3.0.1 to v3.0.16. **Known Issues** - **Wi-Fi** - works, but requires sending commands from a serial monitor 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 adjust timings to enable programming mode due to limitation in its current sensing circuitry #### Summary of key features and/or bug fixes by Point Release **Summary of the key new features added to CommandStation-EX V3.0.16** - Ignore CV1 bit 7 read if rejected by a non NMRA compliant decoder when identifying loco id **Summary of the key new features added to CommandStation-EX V3.0.15** - Send function commands just once instead of repeating them 4 times **Summary of the key new features added to CommandStation-EX V3.0.14** - Add feature to tolerate decoders that incorrectly have gaps in their ACK pulse - Provide proper track power management when joining and unjoining tracks with <1 JOIN> **Summary of the key new features added to CommandStation-EX V3.0.13** - Fix for CAB Functions greater than 127 **Summary of the key new features added to CommandStation-EX V3.0.12** - Fixed clear screen issue for nanoEvery and nanoWifi **Summary of the key new features added to CommandStation-EX V3.0.11** - Reorganized files for support of 128 speed steps **Summary of the key new features added to CommandStation-EX V3.0.10** - Added Support for the Teensy 3.2, 3.5, 3.6, 4.0 and 4.1 MCUs - No functional change just changes to avoid complier warnings for Teensy/nanoEvery **Summary of the key new features added to CommandStation-EX V3.0.9** - Rearranges serial newlines for the benefit of JMRI - Major update for efficiencies in displays (LCD, OLED) - Add I2C Support functions **Summary of the key new features added to CommandStation-EX V3.0.8** - Wraps <* *> around DIAGS for the benefit of JMRI **Summary of the key new features added to CommandStation-EX V3.0.7** - Implemented support for older 28 apeed step decoders - Option to turn on 28 step speed decoders in addition to 128.

The code base was re-architeced and core changes were made to the Waveform generator to reduce overhead and make better use of Arduino.** **Summary of the key new features added in Release v3.0.0 include:** - **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** - `` command allows setting functions based on their number, not based on a code as in `` - **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.
