self.machine.hardware_platforms[‘p3_roc’]¶
-
class
mpf.platforms.p3_roc.
P3RocHardwarePlatform
(machine)¶ Bases:
mpf.platforms.p_roc_common.PROCBasePlatform
,mpf.core.platform.I2cPlatform
,mpf.core.platform.AccelerometerPlatform
Platform class for the P3-ROC hardware controller.
Parameters: machine – The MachineController instance. Accessing the p3_roc platform via code
Hardware platforms are stored in the
self.machine.hardware_platforms
dictionary, so the p3_roc platform is available viaself.machine.hardware_platforms['p3_roc']
.Methods & Attributes
The p3_roc platform has the following methods & attributes available. Note that methods & attributes inherited from base classes are not included here.
-
configure_accelerometer
(number, config, callback)¶ Configure the accelerometer on the P3-ROC.
-
configure_driver
(config: mpf.core.platform.DriverConfig, number: str, platform_settings: dict)¶ Create a P3-ROC driver.
Typically drivers are coils or flashers, but for the P3-ROC this is also used for matrix-based lights.
Parameters: - config – Dictionary of settings for the driver.
- number – Number of this driver.
- platform_settings – Platform specific settings
Returns a reference to the PROCDriver object which is the actual object you can use to pulse(), patter(), enable(), etc.
-
configure_i2c
(number: str)¶ Configure I2C device on P3-Roc.
-
configure_switch
(number: str, config: mpf.core.platform.SwitchConfig, platform_config: dict)¶ Configure a P3-ROC switch.
Parameters: - number – Number of this switch
- config – Dictionary of settings for the switch.
- platform_config – Platform specific settings.
Returns: A configured switch object.
-
connect
()¶ Connect to the P3-Roc.
-
get_hw_switch_states
() → Dict[str, bool]¶ Read in and set the initial switch state.
The P-ROC uses the following values for hw switch states: 1 - closed (debounced) 2 - open (debounced) 3 - closed (not debounced) 4 - open (not debounced)
-
get_info_string
()¶ Dump infos about boards.
-
process_events
(events)¶ Process events from the P3-Roc.
-
classmethod
scale_accelerometer_to_g
(raw_value)¶ Convert internal representation to g.
-
set_gpio
(index, state)¶ Set GPIO state.
-
start
()¶ Start GPIO poller.
-
stop
()¶ Stop platform.
