-/**
- * HC32F460 system clock configuration.
- *
- * With the HC32 HAL, the various peripheral clocks (including the CPU clock) are derived
- * from the main PLL (MPLL-P) output (referred to at F_SYSTEM_CLOCK).
- *
- * F_SYSTEM_CLOCK is the target frequency of the main PLL, and the PLL is automatically configured
- * to achieve this frequency.
- *
- * The peripheral clocks are the result of integer division of F_SYSTEM_CLOCK.
- * Their target frequencies are defined here, and the required division factors are calculated automatically.
- * Note that the division factor must be a power of 2 between 1 and 64.
- * If the target frequency is not achievable, a compile-time error will be generated.
- *
- * Additionally, there are interdependencies between the peripheral clocks, which are described in
- * Section 4.4 "Working Clock Specifications" of the HC32F460 Reference Manual.
- * With Arduino core >= 1.2.0, these interdependencies are checked at compile time.
- * On earlier versions, you are on your own.
- *
- * For all clock frequencies, they can be checked at runtime by enabling the 'ALWAYS_VALIDATE_CLOCKS' define.
- * In MARLIN_DEV_MODE, they will also be printed to the serial console by 'MarlinHAL::HAL_clock_frequencies_dump'.
- *
- * See https://github.com/MarlinFirmware/Marlin/pull/27099 for more information.

 /**
- * XTLW MFF V2.0 pin assignments
+ * Marlin currently requires 3 SPI classes:
+ *
+ * SPIClass:
+ *  This class is normally provided by frameworks and has a semi-default interface.
+ *  This is needed because some libraries reference it globally.
+ *
+ * SPISettings:
+ *  Container for SPI configs for SPIClass. As above, libraries may reference it globally.
+ *
+ * These two classes are often provided by frameworks so we cannot extend them to add
+ * useful methods for Marlin.
+ *
+ * MarlinSPI:
+ *  Provides the default SPIClass interface plus some Marlin goodies such as a simplified
+ *  interface for SPI DMA transfer.

Mihail Dumitrescu	50a38bb365	Optimal number of sqrts and trapezoid calculations. Remove forward_pass(). Call forward_pass_kernel() from recalculate() instead. Fix potential for large speed changes if planner falls behind.	2024-04-29 19:50:15 +03:00
Mihail Dumitrescu	5717a39422	Remove nominal_length, remove MINIMAL_STEP_RATE, add min_entry_speed_sqr, initial clean up of reverse_pass_kernel and forward_pass_kernel. Removing MINIMAL_STEP_RATE allows for correct handling of moves with low acceleration, including fixing judder that's caused when the planner computes an entry speed based on minimum_planner_speed_sqr that's then promptly overriden by MINIMAL_STEP_RATE. Added min_entry_speed_sqr to avoid a specific potential source of judder due to working with discrete steps rather continuous real-valued physics. The first step of any segment runs at initial_rate. If it is too low compared to acceleration_steps_per_s2 it will result in too much accumulated acceleration_time (see stepper.cpp) which will mean the following step will be at a much higher speed, and the speed change will significantly surpass the set acceleration_steps_per_s2 limit. Making sure we can match this limit is why we have minimum_planner_speed_sqr in the first place.	2024-04-29 19:50:15 +03:00

Mihail Dumitrescu	549a4f48f9	Smoother motion by fixing calculating trapezoids and ISR stepping. Fix rounding directions in calculate_trapezoid_for_block(). Fix off-by-ones errors in ac/deceleration steps in block_phase_isr. Half-initialize ac/deceleration_time to smooth the speed change shock that happens between segments, which is critical as jerk/deviation adds to this. The result is a smoother motion profile that follows the imposed acceleration limits with a well defined 0.5-1.5x error factor (or 2x if axis is starting from ~0). Errors are due to converting a real-valued motion profile into discrete numbers of steps. Fixes are general and improve S_CURVE_ACCELERATION too (no endorsement implied). Tested by looking at the generated step/dir impulses with a logic analyzer. Enjoy the smoother motion or use more aggresive acceleration/jerk/deviation values for faster prints. Also improves: #12491	2024-04-24 19:18:17 +03:00
