Warning

This documentation is for an unreleased version of MPF!

This is the developer documentation for MPF 0.51, which is the “dev” (next) release of MPF that is a work-in-progress. Use the “Read the Docs” link in the lower left corner to view the developer docs for the version of MPF you’re using.

self.machine.hardware_platforms[‘fast’]

class mpf.platforms.fast.fast.FastHardwarePlatform(machine)

Bases: mpf.core.platform.ServoPlatform, mpf.core.platform.LightsPlatform, mpf.core.platform.DmdPlatform, mpf.core.platform.SwitchPlatform, mpf.core.platform.DriverPlatform

Platform class for the FAST hardware controller.

Accessing the fast platform via code

Hardware platforms are stored in the self.machine.hardware_platforms dictionary, so the fast platform is available via self.machine.hardware_platforms['fast'].

Methods & Attributes

The fast platform has the following methods & attributes available. Note that methods & attributes inherited from base classes are not included here.

clear_hw_rule(switch, coil)

Clear a hardware rule.

This is used if you want to remove the linkage between a switch and some driver activity. For example, if you wanted to disable your flippers (so that a player pushing the flipper buttons wouldn’t cause the flippers to flip), you’d call this method with your flipper button as the sw_num.

Parameters:
  • switch – The switch whose rule you want to clear.
  • coil – The coil whose rule you want to clear.
configure_dmd()

Configure a hardware DMD connected to a FAST controller.

configure_driver(config: mpf.core.platform.DriverConfig, number: str, platform_settings: dict) → mpf.platforms.fast.fast_driver.FASTDriver

Configure a driver.

Parameters:config – Driver config.

Returns: Driver object

configure_light(number, subtype, platform_settings) → mpf.platforms.interfaces.light_platform_interface.LightPlatformInterface

Configure light in platform.

configure_servo(number: str)

Configure a servo.

Parameters:number – Number of servo

Returns: Servo object.

configure_switch(number: str, config: mpf.core.platform.SwitchConfig, platform_config: dict) → mpf.platforms.fast.fast_switch.FASTSwitch

Configure the switch object for a FAST Pinball controller.

FAST Controllers support two types of switches: local and network. Local switches are switches that are connected to the FAST controller board itself, and network switches are those connected to a FAST I/O board.

MPF needs to know which type of switch is this is. You can specify the switch’s connection type in the config file via the connection: setting (either local or network).

If a connection type is not specified, this method will use some intelligence to try to figure out which default should be used.

If the DriverBoard type is fast, then it assumes the default is network. If it’s anything else (wpc, system11, bally, etc.) then it assumes the connection type is local. Connection types can be mixed and matched in the same machine.

Parameters:config – Switch config.

Returns: Switch object.

static convert_number_from_config(number)

Convert a number from config format to hex.

classmethod get_coil_config_section()

Return coil config section.

get_hw_switch_states()

Return hardware states.

get_info_string()

Dump infos about boards.

classmethod get_switch_config_section()

Return switch config section.

initialize()

Initialise platform.

parse_light_number_to_channels(number: str, subtype: str)

Parse light channels from number string.

process_received_message(msg: str)

Send an incoming message from the FAST controller to the proper method for servicing.

Parameters:msg – messaged which was received
receive_local_closed(msg)

Process local switch closed.

Parameters:msg – switch number
receive_local_open(msg)

Process local switch open.

Parameters:msg – switch number
receive_nw_closed(msg)

Process network switch closed.

Parameters:msg – switch number
receive_nw_open(msg)

Process network switch open.

Parameters:msg – switch number
receive_sa(msg)

Receive all switch states.

Parameters:msg – switch states as bytearray
register_io_board(board)

Register an IO board.

Parameters:board – ‘mpf.platform.fast.fast_io_board.FastIoBoard’ to register
register_processor_connection(name: str, communicator)

Register processor.

Once a communication link has been established with one of the processors on the FAST board, this method lets the communicator let MPF know which processor it’s talking to.

This is a separate method since we don’t know which processor is on which serial port ahead of time.

Parameters:
  • communicator – communicator object
  • name – name of processor
set_pulse_on_hit_and_enable_and_release_and_disable_rule(enable_switch, disable_switch, coil)

Set pulse on hit and enable and release and disable rule on driver.

set_pulse_on_hit_and_enable_and_release_rule(enable_switch: mpf.core.platform.SwitchSettings, coil: mpf.core.platform.DriverSettings)

Set pulse on hit and enable and relase rule on driver.

set_pulse_on_hit_and_release_rule(enable_switch, coil)

Set pulse on hit and release rule to driver.

set_pulse_on_hit_rule(enable_switch: mpf.core.platform.SwitchSettings, coil: mpf.core.platform.DriverSettings)

Set pulse on hit rule on driver.

start()

Start listening for commands and schedule watchdog.

stop()

Stop platform and close connections.

update_firmware() → str

Upgrade the firmware of the CPUs.

update_leds()

Update all the LEDs connected to a FAST controller.

This is done once per game loop for efficiency (i.e. all LEDs are sent as a single update rather than lots of individual ones).

Also, every LED is updated every loop, even if it doesn’t change. This is in case some interference causes a LED to change color. Since we update every loop, it will only be the wrong color for one tick.
