-- This auxiliar platform dependent module defines some hardware devices
|
|
-- available in the specific development kit.
|
|
-- It will be automatically require()d when eLua detects it is running on the
|
|
-- respective platform, exposing auxiliar constants and functions to facilitate
|
|
-- and keep portable the access to the underlying hardware.
|
|
-- The code configures the MCU to interface with the platform devices and
|
|
-- exposes the following objects, constants and fuctions:
|
|
-- Onboard Buttons:
|
|
-- BTN_UP, BTN_DOWN, BTN_LEFT, BTN_RIGHT, BTN_SELECT
|
|
-- Onboard LED:
|
|
-- Auxiliar Function:
|
|
-- btn_pressed( button )
|
|
-- returns true if the arg button is pressed, false otherwise
