ESP-01S智能灯控源码详解

通过前一篇的ESP-01S实现智能灯控，我们可以快速上手智能灯控并获得不错的交互体验。但是在一些突发情况下（如：客户端在家庭中删除了设备），此时就要从墙中取出esp-01s重新刷入固件，操作就会非常繁琐。本文分析灯控装置的源码，并优化固件，以便在突发情况下对灯控装置配网与重置。

一、项目地址

二、源码

2.1 核心代码

#include <EEPROM.h>
#include<wifi_connect_tool.h> //WiFi配网头文件
#include <Arduino.h>
#include <arduino_homekit_server.h>
#define LOG_D(fmt, ...)   printf_P(PSTR(fmt "\n") , ##__VA_ARGS__);
#define PIN_LED 2  			//GPIO2是板载灯
#define PIN_SWITCH 0    //GPIO0是控制继电器的引脚
bool reset_flag = false;

//上电后只执行一次
void setup() {
  Serial.begin(115200);
  pinMode(PIN_SWITCH, OUTPUT);
  digitalWrite(PIN_SWITCH, LOW);//整个装置通电后设置继电器为闭合状态，即电路通。这样就算没有设置装置，也不影响正常使用。
  EEPROM.begin(350);
  wifi_load();							//WiFi配网
  pinMode(PIN_LED, OUTPUT); //设置板载LED灯
  if(reset_flag==true){
      homekit_storage_reset(); //重置homekit
  }
  my_homekit_setup(); 
}

void loop() {
    wifi_pant();//查看wifi情况
    my_homekit_loop();
}

//==============================
// HomeKit setup and loop
//==============================

// access your HomeKit characteristics defined in my_accessory.c
extern "C" homekit_server_config_t config;
extern "C" homekit_characteristic_t cha_switch_on;

static uint32_t next_heap_millis = 0;


void cha_switch_on_setter(const homekit_value_t value) {
  bool on = value.bool_value;
  cha_switch_on.value.bool_value = on;  //sync the value
  LOG_D("Switch: %s", on ? "ON" : "OFF");		//控制台打印日志
  digitalWrite(PIN_SWITCH, on ? LOW : HIGH);//如果电路通则断，断则通
  digitalWrite(PIN_LED, on ? LOW : HIGH);		//这个是控制灯的
}

//接入Homekit后只执行一次
void my_homekit_setup() {
  pinMode(PIN_SWITCH, OUTPUT);
  digitalWrite(PIN_SWITCH, LOW);

  //Add the .setter function to get the switch-event sent from iOS Home APP.
  //The .setter should be added before arduino_homekit_setup.
  //HomeKit sever uses the .setter_ex internally, see homekit_accessories_init function.
  //Maybe this is a legacy design issue in the original esp-homekit library,
  //and I have no reason to modify this "feature".
  cha_switch_on.setter = cha_switch_on_setter;
  arduino_homekit_setup(&config);

  //report the switch value to HomeKit if it is changed (e.g. by a physical button)
  //bool switch_is_on = true/false;
  //cha_switch_on.value.bool_value = switch_is_on;
  //homekit_characteristic_notify(&cha_switch_on, cha_switch_on.value);
}

void my_homekit_loop() {
  arduino_homekit_loop();
  const uint32_t t = millis();
  if (t > next_heap_millis) {
    // show heap info every 5 seconds
    next_heap_millis = t + 5 * 1000;
    LOG_D("Free heap: %d, HomeKit clients: %d",
        ESP.getFreeHeap(), arduino_homekit_connected_clients_count());

  }
}

2.2 配置项

#include <homekit/homekit.h>
#include <homekit/characteristics.h>

void my_accessory_identify(homekit_value_t _value) {
  printf("accessory identify\n");
}

// Switch (HAP section 8.38)
// required: ON
// optional: NAME

// format: bool; HAP section 9.70; write the .setter function to get the switch-event sent from iOS Home APP.
homekit_characteristic_t cha_switch_on = HOMEKIT_CHARACTERISTIC_(ON, false);

// format: string; HAP section 9.62; max length 64
homekit_characteristic_t cha_name = HOMEKIT_CHARACTERISTIC_(NAME, "Switch");

homekit_accessory_t *accessories[] = {
    HOMEKIT_ACCESSORY(.id=1, .category=homekit_accessory_category_switch, .services=(homekit_service_t*[]) {
        HOMEKIT_SERVICE(ACCESSORY_INFORMATION, .characteristics=(homekit_characteristic_t*[]) {
            HOMEKIT_CHARACTERISTIC(NAME, "Switch"),
            HOMEKIT_CHARACTERISTIC(MANUFACTURER, "Arduino HomeKit"),
            HOMEKIT_CHARACTERISTIC(SERIAL_NUMBER, "0123456"),
            HOMEKIT_CHARACTERISTIC(MODEL, "ESP8266/ESP32"),
            HOMEKIT_CHARACTERISTIC(FIRMWARE_REVISION, "1.0"),
            HOMEKIT_CHARACTERISTIC(IDENTIFY, my_accessory_identify),
            NULL
        }),
    HOMEKIT_SERVICE(SWITCH, .primary=true, .characteristics=(homekit_characteristic_t*[]){
      &cha_switch_on,
      &cha_name,
      NULL
    }),
        NULL
    }),
    NULL
};

homekit_server_config_t config = {
    .accessories = accessories,
    .password = "111-11-111"  //加入家庭时的代码为八个1
};
