机智云协议移植到tencent os

腾讯物联网终端操作系统（TencentOS tiny）是腾讯面向物联网领域开发的实时操作系统，具有低功耗，低资源占用，模块化，安全可靠等特点，可有效提升物联网终端产品开发效率。TencentOS tiny 提供精简的 RTOS 内核，内核组件可裁剪可配置，可快速移植到多种主流 MCU 及模组芯片上。而且，基于RTOS内核提供了丰富的物联网组件，内部集成主流物联网协议栈（如 CoAP/MQTT/TLS/DTLS/LoRaWAN/NB-IoT 等），可助力物联网终端设备及业务快速接入腾讯云物联网平台。
在tencentos 移植机智云协议，可以为后续腾讯云平台联合机智云平台开发提供便捷的途径。

首先，新建一个项目，选择腾讯os，选择对应的单片机芯片

然后，我们创建Gizwits 和utils文件夹，并且把从机智云平台下载的通用代码对应文件夹内的文件复制进去

然后到编译器里包含对应的文件夹，格式如图所示：

配置对应的串口中断和定时器中断：

void UART5_IRQHandler(void) __attribute__((interrupt("WCH-Interrupt-fast")));
void TIM6_IRQHandler(void) __attribute__((interrupt("WCH-Interrupt-fast")));

/* Global Variable */
void Uart5_Init(void){
GPIO_InitTypeDefGPIO_InitStructure = {0};
USART_InitTypeDef USART_InitStructure = {0};
NVIC_InitTypeDefNVIC_InitStructure = {0};
RCC_APB1PeriphClockCmd(RCC_APB1Periph_UART5, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOD, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_12;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOC, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOD, &GPIO_InitStructure);

USART_InitStructure.USART_BaudRate = 9600;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Tx | USART_Mode_Rx;

USART_Init(UART5, &USART_InitStructure);
USART_ITConfig(UART5, USART_IT_RXNE, ENABLE);

NVIC_InitStructure.NVIC_IRQChannel = UART5_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);

USART_Cmd(UART5, ENABLE);

}
void Tim6_init(){
TIM_TimeBaseInitTypeDef TIM_InitStructure={0};
NVIC_InitTypeDefNVIC_InitStructure = {0};
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM6, ENABLE);
TIM_InitStructure.TIM_Period=1000-1;
TIM_InitStructure.TIM_CounterMode=TIM_CounterMode_Up;
TIM_InitStructure.TIM_Prescaler=96-1;
TIM_InitStructure.TIM_ClockDivision=TIM_CKD_DIV1;
TIM_TimeBaseInit(TIM6, &TIM_InitStructure);

TIM_ITConfig(TIM6, TIM_IT_Update, ENABLE);

NVIC_InitStructure.NVIC_IRQChannel=TIM6_IRQn;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=0;
NVIC_InitStructure.NVIC_IRQChannelSubPriority=1;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_Init(&NVIC_InitStructure);
TIM_Cmd(TIM6, ENABLE);
}

在中断里引用对应机智云需要的函数：

完善机智云对应的函数：

int32_t uartWrite(uint8_t *buf, uint32_t len)
{
uint32_t i = 0;

if(NULL == buf)
{
   return -1;
}

#ifdef PROTOCOL_DEBUG
GIZWITS_LOG("MCU2WiFi[%4d:%4d]: ", gizGetTimerCount(), len);
for(i=0; i<len; i++)
{
   GIZWITS_LOG("%02x ", buf);
}
GIZWITS_LOG("\n");
#endif

for(i=0; i<len; i++)
{
   //USART_SendData(UART, buf);//STM32 test demo
   //Serial port to achieve the function, the buf sent to the module
   USART_SendData(UART5, buf);
   while (USART_GetFlagStatus(UART5, USART_FLAG_TXE) == RESET);
   if(i >=2 && buf == 0xFF)
   {
      //Serial port to achieve the function, the 0x55 sent to the module
      //USART_SendData(UART, 0x55);//STM32 test demo
         USART_SendData(UART5, 0x55);
         while (USART_GetFlagStatus(UART5, USART_FLAG_TXE) == RESET);
   }
}

return len;
}

在tencent os里新建任务，任务里运行机智云的线程：

#define TASK1_STK_SIZE    2048
k_task_t task1;
__aligned(4) uint8_t task1_stk;

void task1_entry(void *arg)
{
while (1)
{
   userHandle();
   gizwitsHandle((dataPoint_t *)&currentDataPoint);
   tos_task_delay(10);
}
}

在开始任务调度前初始化数据点，然后启动任务和进程调度：
userInit();
   gizwitsInit();
tos_knl_init();
tos_task_create(&task1, "task1", task1_entry, NULL, 3, task1_stk, TASK1_STK_SIZE, 0); // Create task1
tos_knl_start();

效果展示：
