3.2 HTML5
The device control page in WeChat is a H5 page. Using a MQTT client implement in javascript , using the mqttws31.js library:
var client_id = parseInt(Math.random() * 10000, 10) + '_' + mqtt_uname; var client = new Paho.MQTT.Client(mqtt_server, mqtt_port, "/mqtt", client_id); function failConnect(e) { console.log("connect failed"); console.log(e); console.log("reconnecting ..."); client.connect({userName: mqtt_uname, password: mqtt_pass, onSuccess:onConnect, onFailure: failConnect, mqttVersion:3}); } function onConnect() { console.log("onConnect OK!"); subscribe('dev2app/' + devid); } function subscribe(topic) { client.subscribe(topic); } function onMessageArrived (message) { console.log("Arrived Message: [", message.payloadString, "]"); try { job = JSON.parse(message.payloadString); set = job.d; } catch(e) { console.log("JSON object error!"); alert("JSON error, RX data is: " + message.payloadString); return; } if(job.m == 'set' || job.m == 'status') { //console.log("set ui state"); set_ui_state(set); } if(job.m == 'offline') { blockUI(); } } function onDisConnect() { console.log("reconnecting ..."); client.connect({userName: mqtt_uname, password: mqtt_pass, onSuccess:onConnect, onFailure: failConnect, mqttVersion:3}); } function mqtt_publish(msg){ var topic = 'app2dev/' + devid; message = new Paho.MQTT.Message(msg); message.destinationName = topic; client.send(message); console.log("publish message: " + msg); } function mqtt_init() { client.connect({userName: mqtt_uname, password: mqtt_pass, onSuccess:onConnect, onFailure: failConnect, mqttVersion:3}); client.onMessageArrived = onMessageArrived; client.onConnectionLost = onDisConnect; } mqtt_init();

7 Hardware
7.1 Schemmatics
7.2 LED
OpenLight MCPCB, LED lamp bead default layout:
- Red LED 6 series,positive answer 12v, negative link control panel R (OUTA of MY9291)
- Green LED 4 series, positive answer 12v, negative link control panel G (OUTB of MY9291)
- Blue LED 4 series, positive answer 12v, negative link control panel B (OUTC of MY9291)
- White LED*8 (4 series as a set, 2 groups parallel, positive answer 12v, negative link control panel W (OUTC of MY9291)
LED bead (5730) features:
- Size 5.7 x 3.0 mm
- Max current 150mA (0.5W)
- VF is 3.0 - 3.4V (Red LED is 2.0 - 2.2V)
- Brightness 50 - 55 lm
LED bead is just a diode, will light as long as there is a positive forward voltage(VF), 2-3.5V. The bead will not light if voltage below this range and will burn if above this range
Current control the bead brightness, so dimmer switch lamp actually switch the current. If current exceed the rated current that will speed up bead aging and shorten life
7.3 MY9291
OpenLight use the Taiwan Mingyang 4 - channel constant current LED driver ICS to control the R, G, B, w 4 LED lamp bead
- Feature:
- 3.3 - 5V power supply voltage range (±10%)
- Each channel 5-350mA constant current output range
- Maximum output voltage of 24V, support more than one LED in series
- Few external components, only need four external groups to set the four constant - current
- Block Diagrame:
For constant voltage power source, can be cascaded, MCU control of two lines : DI & DCK
- Power supply voltage and lamp bead series/parallel connection and to make sure
- 12V Power supply, 4 LED beads shall be in series if the LED VF is 3V. 6 LED beads shall be in series if the LED VF is 2V
- 24V Power supply, 8 LED beads shall be in series if the LED VF is 3V. 12 LED beads shall be in series if the LED VF is 2V
- 6V Power supply, 2 LED beads shall be in series if the LED VF is 3V. 3 LED beads shall be in series if the LED VF is 2V
- Output current
MY9291, maximum output of 350mA for single channel, in order to save life of lamp beads, can limit the maximum current through the lamp bead to save the life of lamp beads
Maximum output current limit:
R = 380mV / Iout
Full output of 350mA, then each current resistance has to be selected as follows : 1R,1/4 w enough
OpenLight bulbs, R/G/B use 4R7 resistor, and current limit is about 81mA, W use parallel of 2.35R and two 4R7,current limit is about 162mA.This basically limit the current at around 80mA through each 5730 ( 0.5W ) lamp to delay aging of the lamp beads. Thus overall power is limited to 5W, if need to increase the brightness, the 5 4R7 resistor can be replaced by 3R0, also can increase the output power to 7W
