tc-iot-at-sdk-stm32-freertos-based-example 面向使用支持腾讯AT指令的模组(2/3/4/5G、NB、WIFI等)接入腾讯物联网平台的终端设备开发者，mcu侧使用腾讯AT_SDK的移植示例，示例了基于STM32F103 MCU和FreeRTOS的软硬件环境如何实现HAL层的移植，主要有串口的收发接口(中断接收)，延时函数及os相关接口适配（互斥锁、动态内存申请释放、线程创建），适配层接口单独剥离在port目录。

硬件原理图在docs目录，为保证示例的通用性，示例代码除了MCU本身的资源没有无特定外设的访问。 软件的基础工程基于ST的开发工具cubeMX生成，cubeMX工程参加目录下Tc-Iot-STM32F103-Dev-Kit.ioc。
开发者可以参考port目录的HAL层API在STM32和FreeRTOS中移植，切换为新的软硬件平台的相关接口。
hal层对外的API接口及HAL层宏开关控制。
| 序号 | 宏定义 | 说明 |

| 3 | AUTH_MODE_KEY | 认证方式，证书认证还是秘钥认证 |
| 4 | DEBUG_DEV_INFO_USED | 默认使能该宏，设备信息使用调试信息，正式量产关闭该宏，并实现设备信息存取接口 |
该源文件主要实现打印、延时、时间戳、锁、线程创建、设备信息存取等。
| 序号 | HAL_API | 说明 |
|---|---|---|

| 17 | HAL_GetDevInfo | 获取设备信息，必选实现 |
| 18 | HAL_SetDevInfo | 设置设备信息，必须存放在非易失性存储介质，必选实现 |
该源文件主要实现AT串口初始化、串口收发、模组开关机。
| 序号 | HAL_API | 说明 |
|---|---|---|
| 1 | module_power_on | 模组开机，AT串口初始化，必选实现 |
| 1 | module_power_off | 模组关机，低功耗需要，可选实现 |
| 2 | AT_UART_IRQHandler | AT串口接收中断ISR，将收取到的数据放入ringbuff中，AT解析线程会实时解析数据，必选实现 |
| 3 | at_send_data | AT串口发送接口 |
配网/注网 API业务适配，该源文件基于腾讯定义的AT指令实现了MQTT的交互，但有一个关于联网/注网的API(module_register_network)需要根据模组适配。示例基于ESP8266腾讯定制AT固件示例了WIFI直连的方式连接网络，但更常用的场景是根据特定事件（譬如按键）触发配网（softAP/一键配网），这块的逻辑各具体业务逻辑自行实现。ESP8266有封装配网指令和示例APP。对于蜂窝模组，则是使用特定的网络注册指令。开发者参照module_handshake应用AT-SDK的AT框架添加和模组的AT指令交互。
//模组联网（NB/2/3/4G注册网络）、wifi配网（一键配网/softAP）暂时很难统一,需要用户根据具体模组适配。
//开发者参照 module_handshake API使用AT框架的API和模组交互，实现适配。
eAtResault module_register_network(eModuleType eType)
{
eAtResault result = AT_ERR_SUCCESS;
#if (MODULE_TYPE == eMODULE_ESP8266)
#define WIFI_SSID "youga_wifi"
#define WIFI_PW "Iot@2018"
/*此处示例传递热点名字直接联网，通常的做法是特定产品根据特定的事件（譬如按键）触发wifi配网（一键配网/softAP）*/
result = wifi_connect(WIFI_SSID, WIFI_PW);
//result |= wifi_set_test_server_ip("111.230.126.244");
if(AT_ERR_SUCCESS != result)
{
Log_e("wifi connect fail,ret:%d", result);
}
#else
/*模组网络注册、或者wifi配网需要用户根据所选模组实现*/
#endif
return result;
}
调试时，在hal_export.h将设备信息调试宏定义打开。量产时需要关闭该宏定义，实现hal-os中序列17-26的设备信息存取API
#define DEBUG_DEV_INFO_USED
修改下面宏定义的设备信息，则系统将会使用调试信息。
#ifdef DEBUG_DEV_INFO_USED
static char sg_product_id[MAX_SIZE_OF_PRODUCT_ID + 1] = "03UKNYBUZG";
static char sg_device_name[MAX_SIZE_OF_DEVICE_NAME + 1] = "at_dev";
#ifdef AUTH_MODE_CERT
static char sg_device_cert_file_name[MAX_SIZE_OF_DEVICE_CERT_FILE_NAME + 1] = "YOUR_DEVICE_NAME_cert.crt";
static char sg_device_privatekey_file_name[MAX_SIZE_OF_DEVICE_KEY_FILE_NAME + 1] = "YOUR_DEVICE_NAME_private.key";
#else
char sg_device_secret[MAX_SIZE_OF_DEVICE_SERC + 1] = "ttOARy0PjYgzd9OSs4Z3RA==";
#endif
#endif
Smaple目录一共有四个示例，分别是mqtt_sample.c、data_template_sample.c、light_data_template_sample.c。 通过main.c中宏定义 RUN_SAMPLE_TYPE 控制具体运行哪个个示例。
void demoTask(void)
{
mem_info();
if(SHADOW_SAMPLE == RUN_SAMPLE_TYPE)
{
shadow_sample();
}
else if(DATATEMPLATE_SAMPLE == RUN_SAMPLE_TYPE)
{
data_template_sample();
}
else if(LIGHT_SCENARY_SAMPLE == RUN_SAMPLE_TYPE)
{
light_data_template_sample();
}
else
{
mqtt_sample();
}
}
各示例说明如下：
| 序号 | 示例名称 | 说明 |
|---|---|---|
| 1 | mqtt_sample.c | MQTT示例，该示例示例基于定制的AT指令如何便捷的接入腾讯物联网平台及收发数据 |
| 2 | data_template_sample.c | 通用数据模板及事件功能示例，示例如何基于腾讯物联网平台的数据模板功能快速开发产品 |
| 3 | light_data_template_sample.c | 基于智能灯的控制场景，示例具体的产品如何应用数据模板及事件功能 |
按照上述描述，修改宏定义 RUN_SAMPLE_TYPE 为目标示例，编译烧录后，即可运行
MQTT示例
修改 宏定义 RUN_SAMPLE_TYPE 为 MQTT_SAMPLE，AT串口接ESP8266（已烧录腾讯定制AT固件），编译后运行日志如下：
