一、硬件組成如下圖所示：

硬件全家福：

STM32F407ZGT6+ESP8266

二、下載通用APP DEMO：

1.在應(yīng)用商店，搜索“機(jī)智云”APP。

通用APP Demo 又稱“機(jī)智云”APP

2.安裝、注冊(cè)、登陸后如下圖所示：

三、調(diào)試過(guò)程詳解：

創(chuàng)建數(shù)據(jù)點(diǎn)

生成MCU工程

下載MCU工程并根據(jù)開(kāi)發(fā)板原理圖修改工程，修改的地方如程序中紅色加注釋的部分

main.c 中加入紅色標(biāo)出的GPIO初始化代碼

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);

HAL_GPIO_Init(GPIOF, &GPIO_InitStruct);

}

main.h頭文件中增加以下內(nèi)容

/* USER CODE BEGIN Private defines */

#define LED1_Pin GPIO_PIN_9

#define LED0_GPIO_Port GPIOF

/* USER CODE END Private defines */

gizwits_product.c中需要用戶添設(shè)備上電狀態(tài)代碼如下圖所示

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;

}

gizwits_product.c中需要用戶添加的代碼如下圖所示

int8_t gizwitsEventProcess(eventInfo_t *info, uint8_t *gizdata, uint32_t len)

{

uint8_t i = 0;

dataPoint_t *dataPointPtr = (dataPoint_t *)gizdata;

GIZWITS_LOG("Evt: EVENT_Valve %d ", currentDataPoint.valueValve);

}

break;

4.程序燒錄:使用FlyMCU進(jìn)行程序燒寫， 5.打開(kāi)APP操控體驗(yàn)6.打開(kāi)Xcom查看調(diào)試信息

四、注意事項(xiàng)：

1.正確找出開(kāi)發(fā)板的UART2接口：本開(kāi)發(fā)板中對(duì)應(yīng)關(guān)系如下:

UART2_TX：PA2,

UART2_RX：PA3,

2.保證與ESP8266模塊的管腳接線正確：

V3.3（接開(kāi)發(fā)板3.3V）；

GND（接開(kāi)發(fā)板GND）；

TX (接開(kāi)發(fā)板的PA3管腳)；

RX (接開(kāi)發(fā)板的PA2管腳)；

3.由于本次使用的ESP8266是原來(lái)機(jī)智云二代產(chǎn)品上的，可能正常聯(lián)上機(jī)智云，故沒(méi)有給ESP8266燒寫固件，關(guān)于固件燒寫的內(nèi)容，請(qǐng)參閱論壇的相關(guān)文檔。
