Method	`__init__`	Construct the Command Station/Global Configuration.
Constant	`DCC_STATE_MC`	DCC generation - First state machine on PIO 0
Constant	`RC2_STATE_MC`	RailCom Global detector state machine - 3rd on PIO 1
Property	`dcc_pins`	Pins used for DCC generation (DRV8874)
Property	`rc2_pins`	Pins used for RailCom channel 2
Property	`trk_pins`	Pins used for track state monitor
Instance Variable	`_c2_rx_pin`	Undocumented

Instance Variable	`_sleep_pin`	Undocumented

Inherited from HwConf:

Constant	`NP_SM`	NeoPixel State Machine number for RP2040 (Pico, PicoW etc).
Constant	`NP_SM_P2`	State Machine number for RP2350 (Pico2, Pico2W)
Constant	`OLED_I2C`	The oled is on I2C 0 (default GPIO pins 4 & 5).
Property	`max_led`	Number of Leds
Property	`name`	Configuration name for display.
Property	`np_pin`	GPIO Pin for NeoPixel chain.
