Some minor bug fixes such as incorrect error code returned for unknown $-commands and temporary incorrect position reporting on in-flight G92 offset changes.
Added system parameter _tool_table_size, 0 if a tool table is not enabled.
Removed dependency on safety door input for parking settings: $41, $42, $56-$59, $392 and $393.
Removed strict dependency on spindle encoder input for spindle synced motion,
allows the use of the stepper spindle which has an implicit encoder.
Added HAL support for setting serial stream format.
Added setting $681 for configuring Modbus RTU stream parity, available when the underlying driver supports format setting.
these instead of calling via hal.port functions or accessing hal.port properties.
Improved the ioports API, updated core code to make use of it.
Flagged some calls and (part of) some stuctures as deprecated.
Added '$709' setting for second PWM spindle when available - PWM options.
Added properties to PWM spindles to allow "overdriving" PWM output when _RPM controls spindle enable signal is enabled with '$9' or '$709'.
Optimized Modbus CRC calculation, may fix issue with a compiler generating different code compared to most others. Ref. issue #723.
Improved handling of stop realtime command (0x19) for faster motion halt without losing position.
Optimized RAM usage. Fixed regression related to losing current coordinate system and tool offset over a stop.
Some low-level ioport improvements, added definition for virtual pins/ports.
Deprecated direct access to number of the different ioport ports in hal.port struct, use ioports_unclaimed() instead.
Added definitions for up to four additional digital aux I/O ports.
Added real time report of selected spindle in multi spindle configurations. Reported on changes only.
Removed limits override input invert config, for safety reasons it is always active low.
Added HAL entry points for second RGB channel, renamed first from hal.rgb to hal.rgb0.
Added option to setting $22 to force use of limit switches for homing when homing inputs are available in the driver/board combo.
Improved handling of aux I/O pins when claimed for core functions.
Added flag to $9 for disabling laser mode capability for primary PWM spindle. Allows leaving laser mode enabled when a secondary PWM spindle is available and this is used to control a laser.
Added some generic setting definitions for stepper drivers, currently used by the motors plugin.
Fixed incorrect reporting of feed rate modes in $G response.
Added some ioPorts call wrappers, full support for reconfiguring output auxillary pins for PWM output.
The change is major and potentially dangerous, it may damage your probe, so please verify correct operation after installing.
Fix for STM32F4xx issue 161, Ethernet connection unresponsive if USB port not powered.
Enhanced ioPorts interface: New debounce option for input pins that are interrupt capable, currently only possible to enable via plugin code - later to be made available via a $-setting.
Added some wrapper functions for simpler plugin code++
Added simple task scheduler to the core, allows interrupt routines to dispatch jobs to the foreground process, delayed tasks and repeating tasks attached to the 1 ms system timer.
Some drivers and plugins now uses the scheduler for input pin debouncing, regular polling etc. The core uses it for stepper disabling and sleep monitoring.
Allowed use of unused (by the core) axis words (ABCUVW) in M-code commands implemented by plugin code.
Added $PINSTATE command, for outputting auxillary pin states, modes and capabilities. Machine readable formatting.
Implemented handling of single block, block delete and optional stop disable control signal events.
Added help for $S (single block), $B (block delete) and $O (optional stop disable) commands.
Added optional HAL entry point for outputting WRGB values to lights such as neopixels.
Improved $-commands registration to make it easier to add help text.
NOTE: this is a relatively large change and may have introduced bugs and/or unintended side-effects. Please report any issues!
Added setting $519 for binding spindle encoder to given spindle in multi spindle configurations.
Added machine readable spindle enumeration report, $SPINDLESH.
Increased default value for setting $398 (number of planner blocs) from 35 to 100 for faster laser engraving.
NOTE: the $398 setting value will not change on an upgrade!
NOTE: STM32F103 builds for the 128K flash variants does not have enough free RAM and will keep 35 as the default value.
Increased allowed number of decimal places from 3 to 5 for $10x stepper step/mm settings. Ref. ioSender issue 346.
Added setting $650 for filing system options. Ref. issue 397.
Currently the following bits are available (depending on the configuration):
0 - Auto mount SD card on startup (1).
1 - Do not add littlefs files when listing the root directory (2).
Added build option for lathe UVW mode.
When enabled UVW words can be used to command relative moves for XYZ without switching to relative mode with G91.
NOTE: This permanently sets lathe mode and disables the $32 mode setting.
There are signature changes to some spindle, ioports enumeration and VFS filing system mount functions.
Added events to allow plugin code to handle tool table data, possibly stored on a SD card.
