| 36 | Firmata Hardware Abstraction Layer
|
|---|
| 37 |
|
|---|
| 38 | Firmata is built on top of the hardware abstraction functions of Arduino,
|
|---|
| 39 | specifically digitalWrite, digitalRead, analogWrite, analogRead, and
|
|---|
| 40 | pinMode. While these functions offer simple integer pin numbers, Firmata
|
|---|
| 41 | needs more information than is provided by Arduino. This file provides
|
|---|
| 42 | all other hardware specific details. To make Firmata support a new board,
|
|---|
| 43 | only this file should require editing.
|
|---|
| 44 |
|
|---|
| 45 | The key concept is every "pin" implemented by Firmata may be mapped to
|
|---|
| 46 | any pin as implemented by Arduino. Usually a simple 1-to-1 mapping is
|
|---|
| 47 | best, but such mapping should not be assumed. This hardware abstraction
|
|---|
| 48 | layer allows Firmata to implement any number of pins which map onto the
|
|---|
| 49 | Arduino implemented pins in almost any arbitrary way.
|
|---|
| 50 |
|
|---|
| 51 |
|
|---|
| 52 | General Constants:
|
|---|
| 53 |
|
|---|
| 54 | These constants provide basic information Firmata requires.
|
|---|
| 55 |
|
|---|
| 56 | TOTAL_PINS: The total number of pins Firmata implemented by Firmata.
|
|---|
| 57 | Usually this will match the number of pins the Arduino functions
|
|---|
| 58 | implement, including any pins pins capable of analog or digital.
|
|---|
| 59 | However, Firmata may implement any number of pins. For example,
|
|---|
| 60 | on Arduino Mini with 8 analog inputs, 6 of these may be used
|
|---|
| 61 | for digital functions, and 2 are analog only. On such boards,
|
|---|
| 62 | Firmata can implement more pins than Arduino's pinMode()
|
|---|
| 63 | function, in order to accommodate those special pins. The
|
|---|
| 64 | Firmata protocol supports a maximum of 128 pins, so this
|
|---|
| 65 | constant must not exceed 128.
|
|---|
| 66 |
|
|---|
| 67 | TOTAL_ANALOG_PINS: The total number of analog input pins implemented.
|
|---|
| 68 | The Firmata protocol allows up to 16 analog inputs, accessed
|
|---|
| 69 | using offsets 0 to 15. Because Firmata presents the analog
|
|---|
| 70 | inputs using different offsets than the actual pin numbers
|
|---|
| 71 | (a legacy of Arduino's analogRead function, and the way the
|
|---|
| 72 | analog input capable pins are physically labeled on all
|
|---|
| 73 | Arduino boards), the total number of analog input signals
|
|---|
| 74 | must be specified. 16 is the maximum.
|
|---|
| 75 |
|
|---|
| 76 | VERSION_BLINK_PIN: When Firmata starts up, it will blink the version
|
|---|
| 77 | number. This constant is the Arduino pin number where a
|
|---|
| 78 | LED is connected.
|
|---|
| 79 |
|
|---|
| 80 |
|
|---|
| 81 | Pin Mapping Macros:
|
|---|
| 82 |
|
|---|
| 83 | These macros provide the mapping between pins as implemented by
|
|---|
| 84 | Firmata protocol and the actual pin numbers used by the Arduino
|
|---|
| 85 | functions. Even though such mappings are often simple, pin
|
|---|
| 86 | numbers received by Firmata protocol should always be used as
|
|---|
| 87 | input to these macros, and the result of the macro should be
|
|---|
| 88 | used with with any Arduino function.
|
|---|
| 89 |
|
|---|
| 90 | When Firmata is extended to support a new pin mode or feature,
|
|---|
| 91 | a pair of macros should be added and used for all hardware
|
|---|
| 92 | access. For simple 1:1 mapping, these macros add no actual
|
|---|
| 93 | overhead, yet their consistent use allows source code which
|
|---|
| 94 | uses them consistently to be easily adapted to all other boards
|
|---|
| 95 | with different requirements.
|
|---|
| 96 |
|
|---|
| 97 | IS_PIN_XXXX(pin): The IS_PIN macros resolve to true or non-zero
|
|---|
| 98 | if a pin as implemented by Firmata corresponds to a pin
|
|---|
| 99 | that actually implements the named feature.
|
|---|
| 100 |
|
|---|
| 101 | PIN_TO_XXXX(pin): The PIN_TO macros translate pin numbers as
|
|---|
| 102 | implemented by Firmata to the pin numbers needed as inputs
|
|---|
| 103 | to the Arduino functions. The corresponding IS_PIN macro
|
|---|
| 104 | should always be tested before using a PIN_TO macro, so
|
|---|
| 105 | these macros only need to handle valid Firmata pin
|
|---|
| 106 | numbers for the named feature.
|
|---|
| 107 |
|
|---|
| 108 |
|
|---|
| 109 | Port Access Inline Funtions:
|
|---|
| 110 |
|
|---|
| 111 | For efficiency, Firmata protocol provides access to digital
|
|---|
| 112 | input and output pins grouped by 8 bit ports. When these
|
|---|
| 113 | groups of 8 correspond to actual 8 bit ports as implemented
|
|---|
| 114 | by the hardware, these inline functions can provide high
|
|---|
| 115 | speed direct port access. Otherwise, a default implementation
|
|---|
| 116 | using 8 calls to digitalWrite or digitalRead is used.
|
|---|
| 117 |
|
|---|
| 118 | When porting Firmata to a new board, it is recommended to
|
|---|
| 119 | use the default functions first and focus only on the constants
|
|---|
| 120 | and macros above. When those are working, if optimized port
|
|---|
| 121 | access is desired, these inline functions may be extended.
|
|---|
| 122 | The recommended approach defines a symbol indicating which
|
|---|
| 123 | optimization to use, and then conditional complication is
|
|---|
| 124 | used within these functions.
|
|---|
| 125 |
|
|---|
| 126 | readPort(port, bitmask): Read an 8 bit port, returning the value.
|
|---|
| 127 | port: The port number, Firmata pins port*8 to port*8+7
|
|---|
| 128 | bitmask: The actual pins to read, indicated by 1 bits.
|
|---|
| 129 |
|
|---|
| 130 | writePort(port, value, bitmask): Write an 8 bit port.
|
|---|
| 131 | port: The port number, Firmata pins port*8 to port*8+7
|
|---|
| 132 | value: The 8 bit value to write
|
|---|
| 133 | bitmask: The actual pins to write, indicated by 1 bits.
