- 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.
