三、调试过程详解:
创建数据点
生成MCU工程
下载MCU工程并根据开发板原理图修改工程,修改的地方如程序中红色加注释的部分
main.c 中加入红色标出的GPIO初始化代码
static void MX_GPIO_Init(void)
{

GPIO_InitTypeDef GPIO_InitStruct;

/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOE_CLK_ENABLE();
__HAL_RCC_GPIOH_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
__HAL_RCC_GPIOF_CLK_ENABLE(); //GPIOF CLK Enable:Used to Ctrol LED

/*Configure GPIO pins : KEY2_Pin KEY1_Pin */
GPIO_InitStruct.Pin = KEY2_Pin|KEY1_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
GPIO_InitStruct.Pull = GPIO_PULLUP;
HAL_GPIO_Init(GPIOE, &GPIO_InitStruct);

    /*Configure GPIO pin Output Level */

HAL_GPIO_WritePin(GPIOE, LED1_Pin|LED0_Pin, GPIO_PIN_SET);

    /*Configure GPIO pins : LED1_Pin LED0_Pin */

GPIO_InitStruct.Pin = LED1_Pin|LED0_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOF, &GPIO_InitStruct);

}
复制代码
main.h头文件中增加以下内容
/* USER CODE BEGIN Private defines /
#define LED1_Pin GPIO_PIN_9
#define LED1_GPIO_Port GPIOF
#define LED0_Pin GPIO_PIN_10
#define LED0_GPIO_Port GPIOF

/
USER CODE END Private defines */
复制代码

gizwits_product.c中需要用户添设备上电状态代码如下图所示
void userInit(void)
{
memset((uint8_t*)¤tDataPoint, 0, sizeof(dataPoint_t));

/** Warning !!! DataPoint Variables Init , Must Within The Data Range **/ 

  currentDataPoint.valueValve = 0;
  currentDataPoint.valueLED0 = 1;
  currentDataPoint.valueLED1 = 1;
  currentDataPoint.valueState = 1;
  currentDataPoint.valueValue = 5;

}
复制代码

gizwits_product.c中需要用户添加的代码如下图所示

{
uint8_t i = 0;
dataPoint_t *dataPointPtr = (dataPoint_t *)gizdata;

#else

#endif

}

for(i=0; inum; i++)
{

HAL_Delay(500);
HAL_GPIO_TogglePin(LED0_GPIO_Port,LED0_Pin); //led0闪烁 没有阀,用灯替代
HAL_Delay(500);

}
else
{
//user handle
HAL_GPIO_WritePin(LED1_GPIO_Port,LED1_Pin,GPIO_PIN_SET); //熄灭led1
HAL_GPIO_WritePin(LED0_GPIO_Port,LED0_Pin,GPIO_PIN_SET); //熄灭led0

}
break;
case EVENT_LED0:
currentDataPoint.valueLED0 = dataPointPtr->valueLED0;
GIZWITS_LOG(“Evt: EVENT_LED0 %d \n”, currentDataPoint.valueLED0);
if(0x01 == currentDataPoint.valueLED0)
{
//user handle
HAL_GPIO_WritePin(GPIOF,GPIO_PIN_10,GPIO_PIN_RESET); //点亮led0
}
else
{
//user handle
HAL_GPIO_WritePin(GPIOF,GPIO_PIN_10,GPIO_PIN_SET); //熄灭led0

    }
    break;

    GIZWITS_LOG("Evt: EVENT_LED1 %d \n", currentDataPoint.valueLED1);
    if(0x01 == currentDataPoint.valueLED1)
    {

         HAL_GPIO_WritePin(GPIOF,GPIO_PIN_9,GPIO_PIN_RESET);                //点亮led1                        
    }
    else

4.程序烧录:使用FlyMCU进行程序烧写,
5.打开APP操控体验
6.打开Xcom查看调试信息

四、注意事项:
正确找出开发板的UART2接口:本开发板中对应关系如下:UART2_TX:PA2,UART2_RX:PA3,
保证与ESP8266模块的管脚接线正确:V3.3(接开发板3.3V);
GND(接开发板GND);
TX (接开发板的PA3管脚);
RX (接开发板的PA2管脚);
3.由于本次使用的ESP8266是原来机智云二代产品上的,可能正常联上机智云,故没有给ESP8266烧写固件,关于固件烧写的内容,请参阅论坛的相关文档。
