• Enable inversion of direction, steps, and enable via config.h defines

EX-Turntable v0.6.0-Devel

The latest development (Beta) version of EX-Turntable.

This version is a complete re-write into a more manageable codebase, but should not change how it operates.

There is an additional feature to set a gearing factor in config.h to allow use of more than 32,767 steps per revolution, please refer to the documentation at https://dcc-ex.com for more details.

EX-Turntable v0.5.0-Beta

Version history:

v0.5.0-Beta:

• Rename to EX-Turntable in line with re-branding of DCC-EX.
• Add test commands via serial console to replicate diagnostic command for local testing.
• Disable phase switching during homing.
• Increase HOME_SENSITIVITY default to 300 steps due to not moving far enough away from home sensor during calibration.
• Correct stepper configuration for A4988/DRV8825 to use AccelStepper::DRIVER.

v0.4.0-Beta:

Introduced support for traversers and turntables that rotate less than 360 degrees.
Added sensor testing mode that disables all operations and only reports sensor changes to the serial console.
v0.3.1-Beta:

Added automatic phase switching as the default behaviour.
Added the ability to manually define the steps per rotation via config.h.
v0.3.0-Beta:

Initial Beta release.

Turntable-EX v0.2.1-Alpha

This is the next pre-release of the Turntable-EX code ready for practical testing by DCC++ EX team members.

The included README.md file should be sufficient to get up and running.

Note this pre-release needs to be paired up with the latest commit of the add-turntable-controller branch of CommandStation-EX to enable use of the Turntable-EX device driver.

Version history:

Version 0.2.1:

• Bug fix where failed homing puts calibration into infinite loop.
• Calibration no longer initiated automatically if homing fails.

Version 0.2.0:

• Refactor stepper support to enable easy configuration and support for multiple driver types.
• Eliminate defining step count, and use rewrite of the calibration sequence to determine rotational steps which are stored in EEPROM.
• Start up checks EEPROM for step count and initiates calibration if not set.
• Add support for A4988 and DRV8825 as part of the supported stepper options.

Version 0.1.2:

• Fix typo in the TURNTABLE_EX() macro in the README to add the missing "y" to "activit".
• RAM optimisation with Serial.print(F()) and remove Serial.print((String)).
• Enabled RELAY_ACTIVE_STATE to cater for active low or high relays.

Version 0.1.1:

• Updated stepper pin assignments for COUNTER_CLOCKWISE that were missed in 0.1.0.
• Updated typo still referring to home sensor on pin 2.

Version 0.1.0:

• Breaking change due to revised pin allocations, refer to the README for the details.
• Allows for potential future use of pin 2 for interrupts if a DCC version is desired.
• Allows for GC9A01 display option if it proves viable.
• Additionally, the calibration sequence has been simplified.
• Finally, a DEBUG flag has been added so the serial console is cleaner during normal operation, DEBUG can be enabled in config.h.

Version 0.0.9:

• Added calibration sequence.
• Moved config.h include to standard_steppers.h to allow override of the defined step count without having to edit standard_steppers.h which may be overwritten in subsequent releases.

Version 0.0.8:

• Added extra commands to control a LED and an accessory output. LED has on/slow blink/fast blink/off, and accessory simply on/off.

Version 0.0.7:

• Remove unused return status 2, and bugfix in the device driver in CommandStation-EX prevented WAITFOR() EX-RAIL macro working correctly.

Version 0.0.6:

• Move to statically defined home sensor and relay pins.

Version 0.0.5:

• Returns status to the TurntableEX.h device driver when requested.

Version 0.0.4:

• Improvement to homing, limiting rotations to two full turns if homing fails.

Version 0.0.3:

• Bug fix for two homing issues and cleaner debug output.
• Also removed ability for users to enable/disable relay outputs to keep things simple, if users don't wish to use the relay outputs, they can simply leave them unused.

Version 0.0.2:

• Change behaviour so configuration is in EX-RAIL rather than in Turntable-EX directly.
• Steps sent by CommandStation SERVO command, no local position/step configuration.
• Phase switch also by SERVO command.

Version 0.0.1:

• Basic functionality with positions defined in code via array of structs.
• Phase switching via external dual relay.
