Supported Hardware

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 easier2. 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.2 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 what kind of controller you’re running on 3 - 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()

Footnotes

  1. D1MPC = D1 Mini Pin Compatible, accepts Wemos Mini shields (like Terrain-Tronics Castle boards) ↩ ↩2 ↩3

  2. IF you stick within the “curated” set of hardware options. However, there are already a few dozen supported devices and the list continues to grow. ↩ ↩2

  3. Currently supported controllers include Lolin S2 Mini, Lolin S3 Mini, and the Lilygo T-OI Plus ↩
