/**
* 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

* Peltier Bed - Heating and Cooling

* 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

/**
* 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

* Peltier Bed - Heating and Cooling

* 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.)
