+ Firmata Hardware Abstraction Layer
+
+Firmata is built on top of the hardware abstraction functions of Arduino,
+specifically digitalWrite, digitalRead, analogWrite, analogRead, and
+pinMode. While these functions offer simple integer pin numbers, Firmata
+needs more information than is provided by Arduino. This file provides
+all other hardware specific details. To make Firmata support a new board,
+only this file should require editing.
+
+The key concept is every "pin" implemented by Firmata may be mapped to
+any pin as implemented by Arduino. Usually a simple 1-to-1 mapping is
+best, but such mapping should not be assumed. This hardware abstraction
+layer allows Firmata to implement any number of pins which map onto the
+Arduino implemented pins in almost any arbitrary way.
+
+
+General Constants:
+
+These constants provide basic information Firmata requires.
+
+TOTAL_PINS: The total number of pins Firmata implemented by Firmata.
+ Usually this will match the number of pins the Arduino functions
+ implement, including any pins pins capable of analog or digital.
+ However, Firmata may implement any number of pins. For example,
+ on Arduino Mini with 8 analog inputs, 6 of these may be used
+ for digital functions, and 2 are analog only. On such boards,
+ Firmata can implement more pins than Arduino's pinMode()
+ function, in order to accommodate those special pins. The
+ Firmata protocol supports a maximum of 128 pins, so this
+ constant must not exceed 128.
+
+TOTAL_ANALOG_PINS: The total number of analog input pins implemented.
+ The Firmata protocol allows up to 16 analog inputs, accessed
+ using offsets 0 to 15. Because Firmata presents the analog
+ inputs using different offsets than the actual pin numbers
+ (a legacy of Arduino's analogRead function, and the way the
+ analog input capable pins are physically labeled on all
+ Arduino boards), the total number of analog input signals
+ must be specified. 16 is the maximum.
+
+VERSION_BLINK_PIN: When Firmata starts up, it will blink the version
+ number. This constant is the Arduino pin number where a
+ LED is connected.
+
+
+Pin Mapping Macros:
+
+These macros provide the mapping between pins as implemented by
+Firmata protocol and the actual pin numbers used by the Arduino
+functions. Even though such mappings are often simple, pin
+numbers received by Firmata protocol should always be used as
+input to these macros, and the result of the macro should be
+used with with any Arduino function.
+
+When Firmata is extended to support a new pin mode or feature,
+a pair of macros should be added and used for all hardware
+access. For simple 1:1 mapping, these macros add no actual
+overhead, yet their consistent use allows source code which
+uses them consistently to be easily adapted to all other boards
+with different requirements.
+
+IS_PIN_XXXX(pin): The IS_PIN macros resolve to true or non-zero
+ if a pin as implemented by Firmata corresponds to a pin
+ that actually implements the named feature.
+
+PIN_TO_XXXX(pin): The PIN_TO macros translate pin numbers as
+ implemented by Firmata to the pin numbers needed as inputs
+ to the Arduino functions. The corresponding IS_PIN macro
+ should always be tested before using a PIN_TO macro, so
+ these macros only need to handle valid Firmata pin
+ numbers for the named feature.
+
+
+Port Access Inline Funtions:
+
+For efficiency, Firmata protocol provides access to digital
+input and output pins grouped by 8 bit ports. When these
+groups of 8 correspond to actual 8 bit ports as implemented
+by the hardware, these inline functions can provide high
+speed direct port access. Otherwise, a default implementation
+using 8 calls to digitalWrite or digitalRead is used.
+
+When porting Firmata to a new board, it is recommended to
+use the default functions first and focus only on the constants
+and macros above. When those are working, if optimized port
+access is desired, these inline functions may be extended.
+The recommended approach defines a symbol indicating which
+optimization to use, and then conditional complication is
+used within these functions.
+
+readPort(port, bitmask): Read an 8 bit port, returning the value.
+ port: The port number, Firmata pins port*8 to port*8+7
+ bitmask: The actual pins to read, indicated by 1 bits.
+
+writePort(port, value, bitmask): Write an 8 bit port.
+ port: The port number, Firmata pins port*8 to port*8+7
+ value: The 8 bit value to write
+ bitmask: The actual pins to write, indicated by 1 bits.
