可根据自己需求选择对应的功能板和底板，其中gokit3支持SOC模式。
板子电路连接： 参考下图（如图看不清，参考附件中的原图）：https://club.gizwits.com/data/attachment/forum/202103/24/153403ynjs6srw2rnrlz60.jpg.thumb.jpg
云端部署
1.进入新版本开发者中心https://developer.gizwits.com/menu/dashboard，点击左上角创建，选择园艺农林，养殖监控（如果是wifi模式，请选择其他，微信宠物屋gokit，gokit3）。
https://club.gizwits.com/data/attachment/forum/202103/24/153507kpgaagl2fkebnskl.jpg.thumb.jpg
2.如图创建一个产品，产品名称可以根据自己定义https://club.gizwits.com/data/attachment/forum/202103/24/153529i922i80rij2il988.jpg.thumb.jpg
3.将附件中的《数据点.xlsx》文件中的数据点导入产品之中。如果右上角没有管理按钮，那么先随便创建一个数据点之后就有了，之后就可以管理→导入模板https://club.gizwits.com/data/attachment/forum/202103/24/153554h4jznr8878n7r7hn.jpg.thumb.jpg
4.在MCU开发菜单分别生成Arduino代码和STM32代码并进行下载。可按照个人需求和手里面的开发板选择要生成的代码，此处我生成2种代码。

STM32代码移植编写1.下载STM32驱动文件，机智云下载中心下载http://goms-1251025085.cosgz.myq ... 8-1513076127294.rar（也可以在附件中获取）
https://club.gizwits.com/data/attachment/forum/202103/24/153747z8l8llrt5tvud5q3.jpg.thumb.jpg
2.复制STM32驱动文件里面的STM32F103C8x.ioc到下载的代码文件中替换该文件。
https://club.gizwits.com/data/attachment/forum/202103/24/153812nl4cpzzyvjl9cs9y.jpg.thumb.jpg
3.复制驱动库代码_CubeMX版文件夹里面的驱动文件到下载代码的\Hal文件夹。
https://club.gizwits.com/data/attachment/forum/202103/24/153851cr9kzwzx64xv4pt2.jpg.thumb.jpg
4.打开下载代码里面的STM32F103C8x.ioc，需要在电脑上安装CUBEMX，安装方法自行百度。打开之后如下图所示。（此处个人提出建议，任何软件创建项目，不要包含中文路径，否则将会导致很多不可控问题，包括此软件。）
https://club.gizwits.com/data/attachment/forum/202103/24/153916jww13kplah1uo3zu.jpg.thumb.jpg
5.点击右上角generate code生成keil代码。https://club.gizwits.com/data/attachment/forum/202103/24/154058iappmao8iohh08cz.jpg.thumb.jpg
6.生成代码之后用keil打开代码，添加驱动文件到项目

case EVENT_LED_R: currentDataPoint.valueLED_R =dataPointPtr->valueLED_R; GIZWITS_LOG("Evt:EVENT_LED_R%d\n",currentDataPoint.valueLED_R); ledRgbControl(currentDataPoint.valueLED_R,currentDataPoint.valueLED_G,currentDataPoint.valueLED_B); break; case EVENT_LED_G: currentDataPoint.valueLED_G =dataPointPtr->valueLED_G; GIZWITS_LOG("Evt:EVENT_LED_G%d\n",currentDataPoint.valueLED_G); ledRgbControl(currentDataPoint.valueLED_R,currentDataPoint.valueLED_G,currentDataPoint.valueLED_B); break; case EVENT_LED_B: currentDataPoint.valueLED_B =dataPointPtr->valueLED_B; GIZWITS_LOG("Evt:EVENT_LED_B%d\n",currentDataPoint.valueLED_B); ledRgbControl(currentDataPoint.valueLED_R,currentDataPoint.valueLED_G,currentDataPoint.valueLED_B); break; case EVENT_Motor_Speed: currentDataPoint.valueMotor_Speed =dataPointPtr->valueMotor_Speed; GIZWITS_LOG("Evt:EVENT_Motor_Speed%d\n",currentDataPoint.valueMotor_Speed); motorStatus(currentDataPoint.valueMotor_Speed); break;
https://club.gizwits.com/data/attachment/forum/202103/24/154507mq5s34rwd1ay5v88.jpg.thumb.jpg
如使用wifi方案，在WIFI_CON_ROUTER加上关灯操作。case WIFI_CON_ROUTER:
ledRgbControl(0, 250, 0);
https://club.gizwits.com/data/attachment/forum/202103/24/154538cx5oy9i9jx9yu1j1.jpg.thumb.jpg

DataPoint Variables Init ,Must Within The Data Range **/
currentDataPoint.valueLED_OnOff =0; currentDataPoint.valueInfrared =0; currentDataPoint.valueAlert_1 = 0; currentDataPoint.valueAlert_2 = 0; currentDataPoint.valueFault_LED =0; currentDataPoint.valueFault_Motor= 0; currentDataPoint.valueFault_TemHum= 0; currentDataPoint.valueFault_IR =0; currentDataPoint.valueLED_Color =0; currentDataPoint.valueLED_R = 0; currentDataPoint.valueLED_G = 0; currentDataPoint.valueLED_B = 0; currentDataPoint.valueMotor_Speed= 0; currentDataPoint.valueTemperature= 0; currentDataPoint.valueHumidity =0;
https://club.gizwits.com/data/attachment/forum/202103/24/154600cuuff06qqfsx0nhz.jpg.thumb.jpg
userHandle函数的修改，各个数据点的上传，传感器采集。 uint8_t ret = 0; static uint32_t thLastTimer = 0; ///< 新添加代码: 红外传感器数据获取 currentDataPoint.valueInfrared =irHandle(); ///< 新添加代码: 温湿度传感器数据获取 if((gizGetTimerCount()-thLastTimer) > 2000) //上报间隔2S { ret = dht11Read((uint8_t*)¤tDataPoint.valueTemperature,(uint8_t*)¤tDataPoint.valueHumidity); if(ret != 0) { GIZWITS_LOG("Failedtoread DHT11 [%d] \n", ret); } thLastTimer =gizGetTimerCount(); }
