- * Peltier Bed - Heating and Cooling
- *
- * A Peltier device transfers heat from one side to the other in proportion to the amount of
- * current flowing through the device and the direction of current flow. So the same device
- * can both heat and cool.
- *
- * When "cooling" in addition to rejecting the heat transferred from the hot side to the cold
- * side, the dissipated power (voltage * current) must also be rejected. Be sure to set up a
- * fan that can be powered in sync with the Peltier unit.
- *
- * This feature is only set up to run in bang-bang mode because Peltiers don't handle PWM
- * well without filter circuitry.
- *
- * Since existing 3D printers are made to handle relatively high current for the heated bed,
- * we can use the heated bed power pins to control the Peltier power using the same G-codes
- * as the heated bed (M140, M190, etc.).
- *
- * A second GPIO pin is required to control current direction.
- * Two configurations are possible: Relay and H-Bridge
- *
- * (At this time only relay is supported. H-bridge requires 4 MOS switches configured in H-Bridge.)
- *
- * Power is handled by the bang-bang control loop: 0 or 255.
- * Cooling applications are more common than heating, so the pin states are commonly:
- *   LOW  = Heating = Relay Energized
- *   HIGH = Cooling = Relay in "Normal" state

-/**
- * 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.
