SomeRandomBloke 0:98d83f5b309f 27 * @section DESCRIPTION
SomeRandomBloke 0:98d83f5b309f 28 *
SomeRandomBloke 0:98d83f5b309f 29 * This is a basic cheerlights client, http://www.cheerlights.com/ It uses the
SomeRandomBloke 0:98d83f5b309f 30 * API url http://api.thingspeak.com/channels/1417/field/1/last.txt to read the last
SomeRandomBloke 0:98d83f5b309f 31 * colour selected.
SomeRandomBloke 0:98d83f5b309f 32 *
SomeRandomBloke 0:98d83f5b309f 33 * The hardware is the WiFiDIPCortex from SolderSplash Labs http://www.soldersplash.co.uk/products/wifi-dipcortex/
SomeRandomBloke 0:98d83f5b309f 34 * This is a small, yet powerful LPC1347 Cortex M3 dev board with built in CC3000 WiFi module.
SomeRandomBloke 0:98d83f5b309f 35 * The CC3000 uses the TI SmartConfig to setup the WiFi connection without having to update any code.
SomeRandomBloke 0:98d83f5b309f 36 *
SomeRandomBloke 0:98d83f5b309f 37 * The WiFiDIPCortex requires 2 pushbuttons connected between:
SomeRandomBloke 0:98d83f5b309f 38 * Reset: Pin 1 (Reset) and GND, plus 10K resistor between Pin 1 and 3.3V, Pin 11
SomeRandomBloke 0:98d83f5b309f 39 * Config: Pin 6 (P1_31) and GND, plus 10K resistor between Pin 1 and 3.3V, Pin 11
SomeRandomBloke 0:98d83f5b309f 40 *
SomeRandomBloke 0:98d83f5b309f 41 * The LED strip used in this example is based on the WS2801 chips and requires a CLK and DATA to use it.
SomeRandomBloke 0:98d83f5b309f 42 * Pin 27 (P0_7) LED strip Data
SomeRandomBloke 0:98d83f5b309f 43 * Pin 28 (P1_28) LED strip Clk.
SomeRandomBloke 0:98d83f5b309f 44 * Ideally strip should be powered from a external 3.3V source and the GNDs connected between Power supply and
SomeRandomBloke 0:98d83f5b309f 45 * WiFiDIPCortex.
SomeRandomBloke 0:98d83f5b309f 46 *
SomeRandomBloke 0:98d83f5b309f 47 * Debug output is sent to UART connected to pins 19 and 20.
SomeRandomBloke 0:98d83f5b309f 48 *
SomeRandomBloke 0:98d83f5b309f 49 * To use SmartConfig you'll need either the Android or iOS app from http://www.ti.com/tool/SmartConfig.
SomeRandomBloke 0:98d83f5b309f 50 * The Java version hasnt worked so far, but could also be used.
SomeRandomBloke 0:98d83f5b309f 51 * To enter SmartConfig mode, hold down the Config button, then press and release Reset, release Config.
SomeRandomBloke 0:98d83f5b309f 52 * You then use the SmartConfig app to set your network parameters, when you get the notification that
SomeRandomBloke 0:98d83f5b309f 53 * it was successful the WiFiDIPCortex is configured. The settings are saved and available next time it is powered up.
SomeRandomBloke 0:98d83f5b309f 54 *
SomeRandomBloke 0:98d83f5b309f 55 * If SmartConfig fails, try again.
SomeRandomBloke 0:98d83f5b309f 56 *
SomeRandomBloke 0:98d83f5b309f 57 * After starting the WiFiDIPCortex will connect to cheerlights.com and retrieve the latest colour and
SomeRandomBloke 0:98d83f5b309f 58 * set the lights to the colour.
SomeRandomBloke 0:98d83f5b309f 59 * Every minute the colour is retrieved and if its different to the last one the new colour is shown.
SomeRandomBloke 0:98d83f5b309f 60 *
SomeRandomBloke 0:98d83f5b309f 61 * The basic framework can be changed to use different LEDs to suit your available hardware.
SomeRandomBloke 0:98d83f5b309f 62 *
