== Overview == OpenLight Bulb: [[文件:Openbulb-12.jpg | 600px]] [[文件:Openbulb-8.jpg | 600px]] OpenLight Controller: [[文件:OpenLight-Controller-2.jpg | 600px]] [[文件:Openlight-ctrl-demo.jpg | 600px]] <br><br> == Quick Start == [[文件:Maike-wifi-bulb-2955-all-en.jpg]] * Power on, waiting 8s to light * Light is flashing slowly in red means waiting for network connection * If the light is not flashing in red, please turn on and off 3 times, (eg. turn on - light on - turn off, 3 times) the light will be in red gradient for network connection * Connect mobile to Wifi then scan QR code in WeChat to click “Network Connection” * Enter WiFi password, click "Connect" then waiting for network connecting complete. (P.S. only 2.4G WiFi is applicable, 5G WiFi and WiFi enterprise-level security certifications are not applicable) * Complete WiFi configuration, WeChat will be in LAN devices discovery mode. Available devices list will be visible. * Click the first device then press "Link Device" button to bind the device. (P.S. if the device has been binding, then the button at bottom is "Enter Official Account" * Finish above steps, please press "Enter Official Account" button then click "My Device" button to find your binding devices list. Click the device to enter control page. [[文件:Openlight-ui.jpg | 640px]] ;; Note: * If more people need to control the device, please connect to the same router and scan the same QR code while the device is power on. Click "Device connected and skip" -> "Link Device"->"Enter Official Account" to control smart devices * To connect the device to another router in same network, please turn on and off the light 3 times and scan the QR code in Wechat to connect the network, binding is not necessary. * To transfer the device to different place(networks), the light will be in red gradient waiting for networks matching. To connect networks please just scan QR code in WeChat. * Turn on and off the light 6 times to restore the factory settings <br><br> == API == <br><br> == Firmware == === Compile === Getting noduino-sdk: <source lang=bash> $ git clone --recursive git://github.com/icamgo/noduino-sdk.git noduino-sdk </source> Generate toolchain (you need Python 2.7): <source lang=bash> $ cd noduino-sdk/toolchain $ ./gen.py </source> Compile: <source lang=bash> $ cd ../sketch/open-light $ make </source> The generated firmware is located in build/ dir named user1.bin annnd user2.bin Window environment please refer to [[Getting Started with Noduino SDK on Windows]], you can get how to setup the basic developmennt environment <br><br> === Upload === ==== Serial ==== Prepare a USB2UART board, something like FT232RL or CP2102/CP2104: [[文件:Ft232.jpg | 800px]] '''Upload firmware throught serial for OpenLight Bulb:''' [[文件:Openlight-bulb-upload-serial-900.jpg | 600px]]] '''Upload firmware throught serial for OpenLight Controller:''' [[文件:5pin.jpg]] * USB2UART_GND ------> SmartNode_GPIO0 / Bulb_GPIO0 * USB2UAR_GND -----> SmartNode_GND / Bulb_GND * USB2UAR_RXD -----> SmartNode_TX / Bulb_TX * USB2UAR_TXD -----> SmartNode_RX / Bulb_TX Connect USB2UAR_VCC3.3 -----> SmartNode_VCC / Bulb_3V3 at last ESP8285 will be enter upload mode, we can upload the compiled firmware through serial using following commands in Linux: <source lang=bash> $ cd /path/to/noduino-sdk/sketch/open-light $ make produce ESPPORT=/dev/ttyUSB1 </source> In windows: <source lang=bash> $ make produce ESPPORT=COM7 </source> COM7 is your USB2UART device In MAC OS, maybe it's: <source lang=bash> $ make produce ESPPORT=/dev/cu.SLAB_USBtoUART </source> /dev/cu.SLAB_USBtoUART is your USB2UART device <br><br> ==== Online ==== ;; Access: http://dev.noduino.org/openlight ;; Login: * Username: noduino * password: noduino1234 Click the "Add files", select the user1.bin and user2.bin located in /path/to/noduino-sdk/sketch/open-light/build/ Then click "Start upload" to upload the user1.bin and user2.bin into the server temporaily <br><br> == Hardware == === LED === OpenLight 铝基板上,LED 灯珠默认布局为: * Red LED 6 颗串联,正极接 12V,负极接控制板 R (MY9291 之 OUTA) * Green LED 4 颗串联,正极接 12V,负极接控制板 G (MY9291 之 OUTB) * Blue LED 4 颗串联,正极接 12V,负极接控制板 B (MY9291 之 OUTC) * White LED x8 (4 颗串联为一组, 2 组并联,正极接 12V,负极接控制板 W (MY9291 之 OUTC)) LED 灯珠 (5730) 单颗特性为: * 尺寸 5.7 x 3.0 mm * 最大电流 150mA (0.5W) * VF 为 3.0 - 3.4V (Red LED为 2.0 - 2.2V) * 亮度 50 - 55 lm LED 灯珠其实就是一个二极管,只要有一个正向导通电压 (VF) 就能发光,一般为 2 - 3.5V,低于此电压灯珠不能发光,高于此电压,灯珠会烧坏。 控制灯珠亮度的,是电流大小,因此调光灯实际调得是电流的大小。电流超过额定电流,会加速灯珠老化,缩短灯珠寿命 <br><br> === MY9291 === OpenLight 采用台湾明阳 4 通道恒流 LED 驱动芯片,控制 R, G, B, W 四路 LED 灯珠 ;;Feature: * 3.3 - 5V 电源电压范围(±10%) * 每个通道 5 - 350 mA 恒流输出范围 * 可承受最大输出电压 24V,支持多颗 LED 串联 * 外接器件少,仅需四个外接电组来设定四組恆流电流 ;;Block Diagrame: [[文件:MY9291.app.jpg | 600px]] 电源为恒压源,可以多片级联,MCU 的控制线就两个:DI 和 DCK ;; 电源电压与灯珠串并联确定: * 12V 电源的情形,如选用 VF 为 3V 左右的 LED 灯珠,则需要 4 颗串联,这样每颗灯珠分到电压为 3V 左右;2V 左右的灯珠,则需要 6 颗串联 * 24V 电源,则 3V 灯珠 8 颗串联,2V 灯珠 12 颗串联 * 6V 电源,则 3V 灯珠 2 颗串联,2V 灯珠 3 颗串联 ;; 输出限流 MY9291 单路最大输出 350mA,为节约灯珠寿命,可限制通过灯珠的最大电流以节约灯珠寿命 最大输出电流限制: R = 380mV / Iout 满输出 350mA,则每路的限流电阻都得选为:1R,1/4 W 够用 OpenLight 球泡灯,R/G/B 选用电阻 4R7,限流为 81mA 左右,W 用两个 4R7 并联 2.35R 左右,限流为 162mA 左右。这样基本限制经过每颗 5730 (0.5W) 灯珠的电流为 80mA 左右,以延迟灯珠老化。这样整体功率被限制在 5W,如要增加亮度,可将这 5 个 4R7 电阻替换为 3R0,可将输出功率增加到 7W <br><br> == Power == === 12V === 220V 转 12V 恒压电源模块,额定 12W,1A 电流输出 <br><br> === 3.3V === ESP8266/ESP8285 chip、MY9291/MY9231 chip、SPI Flash chip are all 3.3V power. ==== MP1470 ==== * Wide 4.7V to 16V Operating Input Range * Fixed 500kHz Switching Frequency * Over-Current Protection and Hiccup * Thermal Shutdown * Output Adjustable from 0.8V * Available in a 6-pin TSOT-23 package [[文件:Mp1470-typical.jpg]] <br><br> ==== MP2359 ==== * Wide 4.5V to 24V Operating Input Range * 1.2A Peak Output Current * 0.35Ω Internal Power MOSFET Switch * Stable with Low ESR Output Ceramic Capacitors * Up to 92% Efficiency * 0.1μA Shutdown Mode * Fixed 1.4MHz Frequency * Thermal Shutdown * Cycle-by-Cycle Over Current Protection * Output Adjustable from 0.81V to 15V [[文件:Mp2359-sch.jpg]] <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br>
