- Add local UI methods to get heater timeout state.
- Add methods to resume timed-out heaters.
- Re-enable heaters on UI temperature request.
- Make `ExtUI` show a dialog box if pause needs a button press after reheat.
Allow `ENABLED`, `DISABLED`, `PIN_EXISTS`, and `BUTTON_EXISTS` to take multiple arguments. Also add:
- Alias `ANY(...)` for `!DISABLED(...)`
- Alias `ANY_PIN(...)` for `PIN_EXISTS(a) || PIN_EXISTS(b) ...`
- Alias `EITHER(A,B)` for `ANY(...)`
- Alias `ALL(...)` and `BOTH(A,B)` for `ENABLED(...)`
- `NONE(...)` for `DISABLED(...)`
- Send notifications to ExtUI for M0/M1
- wait_for_user can be non-volatile (not changed by interrupt)
C / C++ compilers don't optimize away reads of non-volatile variables when a function call is used between accesses, because *any* variable could be changed by the function call. Since `wait_for_user` can't be changed without a function call, it should be non-volatile so the compiler can optimize away cases where it is read more than once without an intervening function call.
* Make ExtUI respect MAXTEMP limits
- Temperatures are now clamped by MAXTEMP limits rather than arbitrary values.
* Speed up USB init, add status
- Speed up USB initialization
- Show status message if init failed
* Enable status messages for EXTENSIBLE_UI
* Adjust max limit to MAX_TEMP - 15
* Misc. tweaks to formatting, const, etc.
* Move special characters to language.h
* Apply some naming standards
* Clean up menu item draw functions
* Rename some Temperature methods
* UI => ExtUI
* Encapsulate common LCD code in a singleton
* Depend more UBL code on UBL_DEVEL_DEBUGGING
- Since most users don't need the debugging on at all times, this helps reduce the default build size for UBL by over 2K, a little closer to fitting on 128K boards.
- Add `axis_t`, `extruder_t`, `heater_t`, and `fan_t` to eliminate ambiguity, improve type safety.
- Regularized getter/setter argument order and naming.
- `setAxisPosition` no longer stacks moves in the buffer, allowing it to be called repeatedly on each touch ui tap.
- Implement better manual moves for `EXTENSIBLE_UI` (#12205)
- Calling `setAxisPosition_mm` no longer buffers the entire move to the new position, but instead causes small moves towards it to be made during the idle loop. This allows the user to adjust the destination even after the move has started and makes the UI feel much more responsive.
- As suggested by @ejtagle, the new code keeps the planner buffer full to ensure smooth motion without stops and starts.
- Change `En`, `Hn` and `FANn` to zero-based indices.
- Labels consistent with the rest of Marlin code.
