Access to the DWT peripheral for the `CYCCNT` register needs to happen before `main()`. The code needs to be called after the setup of the system clocks, so the right place is between the `premain()` and `main()` function of the STM32 Arduino core.
This patch moves the DWT access code to a new function, which is then placed between `premain()` and `main()`.
Responding to #12383
XY probe offsets should be integers because adding decimal points makes the code larger. But if decimals are very much wanted, this commit removes the old restriction.
* Enable SD Card on RepRap Display and RADDS
Define the necessary pins in `pins_RADDS.h` (copied from the `RADDS_DISPLAY` section) for the use of the SD card slot on RRD.
* Move special characters to language.h
* Apply some naming standards
* Clean up menu item draw functions
* Rename some Temperature methods
* UI => ExtUI
Fix#12416
Better handling of `ENABLED(MIXING_EXTRUDER) && !MIXING_VIRTUAL_TOOLS > 1` - to not fall through to the general case. Fix compiler warnings for `#elif EXTRUDERS < 2`.
See if this has any deleterious effect on motion planning by slicers that inser their own jerk and acceleration controls. The problem I see is that these settings can take effect on blocks already in the planner, and the only way around this would be to shadow these settings in planner blocks and use the shadowed settings in the planner.
* 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.
