Interfaces

Global Attributes

These attributes are available to all modules and interfaces in a design.

Assign the LCSC ID of the module.

If set, this will tell the picker to select that part from LCSC for this block.

This module's manufacturer name, as a string.

Only exact matches on the manufacturer's name will be found by the picker. It's recommended to fill this information based on what ato create component provides.

This module's manufacturer part number, as a string.

For the picker to select the correct part from the manufacturer, this must be set.

The package of the module.

This drives which components can be selected, and what footprint is used.

Must exactly match a known package name.

When set on an interface, this will override the net name of the interface.

This is useful for renaming nets which are automatically generated.

Only for ModuleInterfaces. If set to True, require that interface is connected to something outside of the module it's defined in.

```ato Basic Usage import LEDIndicator, ElectricPower, ElectricLogic

Basic LED indicator (active high)

status_led = new LEDIndicator(use_mosfet=False, active_low=False)

Connect power supply

power_5v = new ElectricPower assert power_5v.voltage within 5V +/- 5% status_led.power_in ~ power_5v

Connect control signal

status_signal = new ElectricLogic status_signal.reference ~ power_5v status_led.logic_in ~ status_signal

Connect to microcontroller

microcontroller.gpio_status ~ status_signal.line

Configure LED properties

status_led.led.led.color = LED.Color.GREEN status_led.led.led.current = 20mA +/- 5% status_led.led.led.forward_voltage = 2.1V +/- 10%

High-power LED with MOSFET driver

power_led = new LEDIndicator(use_mosfet=True, active_low=False) power_led.power_in ~ power_5v power_led.logic_in ~ power_control_signal power_led.led.led.current = 100mA +/- 10% # Higher current

Active-low indicator (ON when signal is LOW)

error_led = new LEDIndicator(use_mosfet=False, active_low=True) error_led.power_in ~ power_5v error_led.logic_in ~ error_signal error_led.led.led.color = LED.Color.RED

Common applications: status indication, debugging, user feedback
