Device Configuration

In order to use all the nifty hardware that provides Inputs and/or Outputs, LCPF needs to know what hardware you are using. This is usually a fairly complex part of an embedded project. LCPF makes this much easier¹. For example, if you use a Lolin S2 Mini with a Terrain-Tronics Caernarfon Castle Kit , IR remote, 35 NeoPixel LEDS, and two servo motors, your entire code for device configuration could be as simple as


    caernarfon = mainManager.TerrainTronics.addCaernarfon(neoPixelCount=35)
    doorMotor = caernarfon.initServo( 1, "doorDrive" )
    windowMotor = caernarfon.initServo( 2, "windowMotor" )
    remote = caernarfon.addIrRemote()

No pins assignments, no addresses, no board types - LCPF handles all that for you.¹ For example, if you use a Lolin S2 Mini with a Terrain-Tronics Caernarfon Castle Kit , configuration is as simple as


caernarfon = mainManager.TerrainTronics.addCaernarfon()

There’s no need to specify what kind of controller you’re running on ² - LCPF figures that out for you. And since it knows where the various parts of the Caernarfon Castle board are connected, there’s no need to specify pin assignments. So if you are using the IR remote, 35 NeoPixel LEDS, and two servo motors, your entire code for device configuration could be


    caernarfon = mainManager.TerrainTronics.addCaernarfon(neoPixelCount=35)
    doorMotor = caernarfon.initServo( 1, "doorDrive" )
    windowMotor = caernarfon.initServo( 2, "windowMotor" )
    remote = caernarfon.addIrRemote()
