- * 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
