* 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.
- Drop `pgm_read_*_near` and let headers choose.
- Define `USE_EXECUTE_COMMANDS_IMMEDIATE` as a conditional.
- Add `process_subcommands_now` for SRAM-based commands.
* Allow override of soft SPI pins in `pins_*.h`
* Add default case to avoid compiler warning.
* Additional pin definitions for Archim 2.
* Einsy Retro has same timings as Einsy Rambo.
- When LCD_SET_PROGRESS_MANUALLY was disabled and an SD print was not active (i.e. the printer was idle), progress_bar_percent would read uninitialized memory from stack and cause progress bar to jump wildly.
- Also updated conditions in `#ifdef` to match `ultralcd.cpp`
Some users may prefer to hide the position updates on the `LIGHTWEIGHT_UI` altogether. This leads to an even less cluttered display (it also saves on SPI traffic and one byte of RAM).
- This status screen uses the ST7920 character generator to greatly
reduce SPI traffic and MCU load when updating the status screen.
- Has been tested with the RepRapDiscount Full Graphics Smart Controller
but should work with any LCD that uses an ST7920 or fully compatible
controller.
