class documentation

class HwConfLcl(HwConf):

Constructor: HwConfLcl()

Hardware configuration for the Quad local PCB.

This provides the hardware configuration for the Quad Local RailCom detector board (RC_LCL_4).

Class Method	`get_instance`	Get the Hardware configuration instance.
Method	`__init__`	Construct the Local Configuration.
Method	`get_lcl_det`	Get local detector hardware assignements.
Constant	`BLK_I2C`	block occupancy is on I2C 1(default GPIO pins 6 & 7)
Instance Variable	`MAX_LED`	Number of NeoPixels.
Property	`dcc_sense`	GPIO pin for DCC power on sense.
Instance Variable	`_dcc_sense`	Undocumented
Instance Variable	`_max_led`	Undocumented
Instance Variable	`_rx_pin`	Undocumented
Instance Variable	`_state_machine`	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.
Class Variable	`_hw_conf`	Undocumented
Instance Variable	`_name`	Undocumented
Instance Variable	`_np_pin`	Undocumented

@classmethod

def get_instance(cls): ¶

overrides rp2da2.lib.hw_conf.HwConf.get_instance

Get the Hardware configuration instance.

This returns the singleton Local Hardware Config instance.

Returns
The DCC Command instance

def __init__(self): ¶

overrides rp2da2.lib.hw_conf.HwConf.__init__

Construct the Local Configuration.

Define DCC sense pin used for detectiing cutouts and allocate pin numbser and state machine number for each local detector.

def get_lcl_det(self, i): ¶

Get local detector hardware assignements.

Parameters
i	index number of detector (in range 0 to 3)

Returns
the pin number for received data and the state machine number
