创建完所有数据点之后。点击MCU开发,按照下图完成设置之后生成ardunio uno r3代码。生成好代码之后下载代码解压代码,导入到项目到开发环境之中(需要把文件解压到软件的库目录下,否则会编译不过)导入项目之后修改程序,对于程序介绍,此处我挑重点,其余代码请自行下载附件查看。为了方便查看增加的代码,这个地方我就不再增加库,而是全部用驱动的方式来实现。
首先来看一下DHT11。我们使用的是A0引脚,也就是第PC5引脚,驱动pin14代码如下int temp;//温度
int humi;//湿度
int tol;//校对码
int j;
unsigned int loopCnt;
int chr = {0};//创建数字数组,用来存放40个bit
unsigned long time;
#define DHT11 14
//温湿度采集
void read_dht11()
{
//delay(1000);//注意采集间隔应该大于1秒
//设置19号接口模式为:输出
//输出低电平20ms(>18ms)
//输出高电平40μs
pinMode(DHT11,OUTPUT);
digitalWrite(DHT11,LOW);
delay(20);
digitalWrite(DHT11,HIGH);
delayMicroseconds(40);
digitalWrite(DHT11,LOW);
//设置2号接口模式:输入
pinMode(DHT11,INPUT);
//高电平响应信号
loopCnt=10000;
while(digitalRead(DHT11) != HIGH)
{
if(loopCnt-- == 0)
{
//如果长时间不返回高电平,跳出程序。
break;
}
}
//低电平响应信号
loopCnt=30000;
while(digitalRead(DHT11) != LOW)
{
if(loopCnt-- == 0)
{
//如果长时间不返回低电平,跳出程序。
break;
}
}
//开始读取bit1-40的数值
for(int i=0;i<40;i++)
{
while(digitalRead(DHT11) == LOW)
{}
//当出现高电平时,记下时间“time”
time = micros();
while(digitalRead(DHT11) == HIGH)
{}
//当出现低电平,记下时间,再减去刚才储存的time
//得出的值若大于50μs,则为‘1’,否则为‘0’
//并储存到数组里去
if (micros() - time >50)
{
chr=1;
}else{
chr=0;
}
}
//湿度,8位的bit,转换为数值
humi=chr*128+chr*64+chr*32+chr*16+chr*8+chr*4+chr*2+chr;
//温度,8位的bit,转换为数值
temp=chr*128+chr*64+chr*32+chr*16+chr*8+chr*4+chr*2+chr;
//校对码,8位的bit,转换为数值
tol=chr*128+chr*64+chr*32+chr*16+chr*8+chr*4+chr*2+chr;
//输出:温度、湿度、校对码
//校对码,我这里没用上
//理论上,湿度+温度=校对码
//如果数值不相等,说明读取的数据有错。
bgn;//跳出程序,可能是没查DHT11可修改成报警或者故障
}
接下来修改按键,按键要把管脚修改过去,按键的管脚分别是A4 A5 对应1819,修改过后:#define KEY1 18
#define KEY2 19
bool led = 0;//LED状态,控制的时候进行取反
bool gdq = 0;//继电器状态控制的时候进行取反
同时修改长短按键。
void KEY_Handle(void)
{
/*Press for over than 3 second is Long Press*/
switch (gokit_keydown())
{
case KEY1_SHORT_PRESS:
if(led)
{
led=0;
mySerial.println(F("KEY1_SHORT_PRESS LED OFF"));
}
else
{
led=1;
mySerial.println(F("KEY1_SHORT_PRESS LED ON"));
}
break;
case KEY1_LONG_PRESS:
mySerial.println(F("KEY1_LONG_PRESS Soft AP mode"));
myGizwits.setBindMode(WIFI_SOFTAP_MODE);
//Soft AP mode
break;
case KEY2_SHORT_PRESS:
if(gdq)
{
gdq=0;
mySerial.println(F("KEY2_SHORT_PRESS LED OFF"));
}
else
{
gdq=1;
mySerial.println(F("KEY2_SHORT_PRESS LED ON"));
}
break;
case KEY2_LONG_PRESS:
mySerial.println(F("KEY2_LONG_PRESS ,AirLink mode"));
myGizwits.setBindMode(WIFI_AIRLINK_MODE);
//AirLink mode
break;
default:
break;
}
}
到此按键就修改完了,接下来修改用户处理函数,没安装notepad++的最好安装一个,用记事本也行,个人习惯用notepad++。修改其他代码需要用到。利用notepad++打开gizwits_protocol.h文件,修改数据上报时间为1秒或者2秒,此处我修改为2秒#define REPORT_TIME_MAX 2000 //2S,打开gizwits_product.c文件,里面绝大部分程序思维按照类上一篇帖子的思维进行修改。将以下内容补充完整。在gizwits_product.c里面
case EVENT_switch_led:
currentDataPoint.valueswitch_led = dataPointPtr->valueswitch_led;
attrFlags.flagswitch_led = 1;
if(0x01 == currentDataPoint.valueswitch_led)
{
led=1;//打开大功率LED
}
else
{
led=0;//关闭大功率LED
}
break;
case EVENT_switch_relay:
currentDataPoint.valueswitch_relay = dataPointPtr->valueswitch_relay;
attrFlags.flagswitch_relay = 1;
if(0x01 == currentDataPoint.valueswitch_led)
{
gdq=1;//打开继电器
}
else
{
gdq=0;//关闭继电器
}
break;
case EVENT_color_controls:
currentDataPoint.valuecolor_controls = dataPointPtr->valuecolor_controls;
attrFlags.flagcolor_controls = 1;
mode_Cloud_data=currentDataPoint.valuecolor_controls;
break;
case EVENT_LED_R:
currentDataPoint.valueLED_R = dataPointPtr->valueLED_R;
attrFlags.flagLED_R = 1;
mode_Cloud_data=currentDataPoint.valueLED_R;//红色值
if(mode_Cloud_data!=1)mode_Cloud_data=1;//自定义
break;
case EVENT_LED_G:
currentDataPoint.valueLED_G = dataPointPtr->valueLED_G;
attrFlags.flagLED_G = 1;
mode_Cloud_data=currentDataPoint.valueLED_G;//绿色值
if(mode_Cloud_data!=1)mode_Cloud_data=1;//自定义
break;
case EVENT_LED_B:
currentDataPoint.valueLED_B = dataPointPtr->valueLED_B;
attrFlags.flagLED_B = 1;
mode_Cloud_data=currentDataPoint.valueLED_B;//蓝色值
if(mode_Cloud_data!=1)mode_Cloud_data=1;//自定义
break;
在文件开头全局一个int mode_Cloud_data={0};//云端数据缓存0模式 1R 2G 3B
接下来回到Ardunio软件,增加RGB驱动函数。定义管脚int redPin = 9 ;
int greenPin = 10;
int bluePin = 11;
初始化
pinMode(redPin ,OUTPUT);
pinMode(greenPin ,OUTPUT);
pinMode(bluePin ,OUTPUT);
RGB控制函数
//rgb控制
void RGB_light_set_color(int red,int green,int blue)
{
analogWrite(redPin,red);
analogWrite(greenPin,green);
analogWrite(bluePin,blue);
}
接下来我们需要新增用户处理的函数//用户处理函数
void setsystem()
{
if(led) digitalWrite(LED_SW,LOW);
else digitalWrite(LED_SW,HIGH);
if(gdq) digitalWrite(GDQ_SW,LOW);
else digitalWrite(GDQ_SW,HIGH);
switch(mode_Cloud_data)
{
case 0 :
RGB_light_set_color(0,0,0);//关闭灯
currentDataPoint.valuecolor_controls = 0;
currentDataPoint.valueLED_R = 0;
currentDataPoint.valueLED_G = 0;
currentDataPoint.valueLED_B = 0;
break;
case 1 :
RGB_light_set_color(mode_Cloud_data,mode_Cloud_data,mode_Cloud_data);//自定义
currentDataPoint.valuecolor_controls = 1;
currentDataPoint.valueLED_R = mode_Cloud_data;
currentDataPoint.valueLED_G = mode_Cloud_data;
currentDataPoint.valueLED_B = mode_Cloud_data;
break;
case 2 :
RGB_light_set_color(255,0,0);//红色
currentDataPoint.valuecolor_controls = 2;
currentDataPoint.valueLED_R = 255;
currentDataPoint.valueLED_G = 0;
currentDataPoint.valueLED_B = 0;
break;
case 3 :
RGB_light_set_color(0,255,0);//绿色
currentDataPoint.valuecolor_controls = 3;
currentDataPoint.valueLED_R = 0;
currentDataPoint.valueLED_G = 255;
currentDataPoint.valueLED_B = 0;
break;
case 4 :
RGB_light_set_color(0,0,255);//蓝色
currentDataPoint.valuecolor_controls = 4;
currentDataPoint.valueLED_R = 0;
currentDataPoint.valueLED_G = 0;
currentDataPoint.valueLED_B = 255;
break;
case 5 :
RGB_light_set_color(255,255,0);//黄色
currentDataPoint.valuecolor_controls = 5;
currentDataPoint.valueLED_R = 255;
currentDataPoint.valueLED_G = 255;
currentDataPoint.valueLED_B = 0;
break;
case 6 :
RGB_light_set_color(255,0,255);//紫色
currentDataPoint.valuecolor_controls = 6;
currentDataPoint.valueLED_R = 255;
currentDataPoint.valueLED_G = 0;
currentDataPoint.valueLED_B = 255;
break;
case 7 :
RGB_light_set_color(255,52,179);//粉色(估计不是粉色)
currentDataPoint.valuecolor_controls = 7;
currentDataPoint.valueLED_R = 255;
currentDataPoint.valueLED_G = 52;
currentDataPoint.valueLED_B = 179;
break;
case 8 :
RGB_light_set_color(255,255,255);//白色
currentDataPoint.valuecolor_controls = 8;
currentDataPoint.valueLED_R = 255;
currentDataPoint.valueLED_G = 255;
currentDataPoint.valueLED_B = 255;
break;
default:
break;
}
}
将setsystem();函数放在loop里面,同时吧DHT11也放进去setsystem();
read_dht11();
currentDataPoint.valuetemperature = temp;
currentDataPoint.valuehumidity = humi;
