You request the use of a +header file in your project source file (C, C++, etc) located in `src` folder +by including it, with the C preprocessing directive `#include'. + +```src/main.c + +#include "header.h" + +int main (void) +{ + ... +} +``` + +Including a header file produces the same results as copying the header file +into each source file that needs it. Such copying would be time-consuming +and error-prone. With a header file, the related declarations appear +in only one place. If they need to be changed, they can be changed in one +place, and programs that include the header file will automatically use the +new version when next recompiled. The header file eliminates the labor of +finding and changing all the copies as well as the risk that a failure to +find one copy will result in inconsistencies within a program. + +In C, the usual convention is to give header files names that end with `.h'. +It is most portable to use only letters, digits, dashes, and underscores in +header file names, and at most one dot. + +Read more about using header files in official GCC documentation: + +* Include Syntax +* Include Operation +* Once-Only Headers +* Computed Includes + +https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html diff --git a/lib/README b/lib/README new file mode 100644 index 0000000..6debab1 --- /dev/null +++ b/lib/README @@ -0,0 +1,46 @@ + +This directory is intended for project specific (private) libraries. +PlatformIO will compile them to static libraries and link into executable file. + +The source code of each library should be placed in a an own separate directory +("lib/your_library_name/[here are source files]"). + +For example, see a structure of the following two libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html +| | +| |--Foo +| | |- Foo.c +| | |- Foo.h +| | +| |- README --> THIS FILE +| +|- platformio.ini +|--src + |- main.c + +and a contents of `src/main.c`: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +PlatformIO Library Dependency Finder will find automatically dependent +libraries scanning project source files. + +More information about PlatformIO Library Dependency Finder +- https://docs.platformio.org/page/librarymanager/ldf.html diff --git a/platformio.ini b/platformio.ini new file mode 100644 index 0000000..4fe4308 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,18 @@ +; PlatformIO Project Configuration File +; +; Build options: build flags, source filter +; Upload options: custom upload port, speed and extra flags +; Library options: dependencies, extra library storages +; Advanced options: extra scripting +; +; Please visit documentation for the other options and examples +; https://docs.platformio.org/page/projectconf.html + +[env:nodemcuv2] +platform = espressif8266 +board = nodemcuv2 +framework = arduino +lib_deps = + marcoschwartz/LiquidCrystal_I2C@^1.1.4 + arduino-libraries/NTPClient@^3.2.1 + beegee-tokyo/DHT sensor library for ESPx@^1.19 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..7ee4831 --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,101 @@ +#include // https://github.com/johnrickman/LiquidCrystal_I2C +#include // https://github.com/arduino-libraries/NTPClient +#include +#include +#include "DHTesp.h" // https://github.com/beegee-tokyo/DHTesp + +#define buzzerPin 15 // define buzzer connected pin +#define dhtPin 2 // define dht connected pin +#define dhtType DHTesp::DHT11 // Define dht sensor type + +const char *ssid = ""; // Wifi SSID +const char *password = ""; // Wifi Password + +const long utcOffsetInSeconds = 0; // Set your timezone 1 hour = 3600 second + +bool executed = false; +bool Fahrenheit = false; // If you want change temperature unit to Fahrenheit set true +const char *ntpServerUrl = ""; // Set npt server url + // https://www.ntppool.org/en/ + +DHTesp dht; +WiFiUDP ntpUDP; +LiquidCrystal_I2C lcd(0x27, 16, 2); +NTPClient timeClient(ntpUDP, ntpServerUrl, utcOffsetInSeconds); + +void lcdClockDate(); +void TempHum(); +void ringBuzzer(); + +void setup() +{ + pinMode(buzzerPin, OUTPUT); + lcd.init(); + lcd.backlight(); + WiFi.begin(ssid, password); + dht.setup(dhtPin, dhtType); + while (WiFi.status() != WL_CONNECTED) + { + delay(500); + lcd.setCursor(0, 0); + lcd.print("Connecting to"); + lcd.setCursor(3, 1); + lcd.print(ssid); + } + lcd.clear(); + timeClient.begin(); +} + +void loop() +{ +} +void lcdClockDate() +{ + time_t epochTime = timeClient.getEpochTime(); + String formattedTime = timeClient.getFormattedTime().substring(0, 5); + struct tm *ptm = gmtime((time_t *)&epochTime); + int monthDay = ptm->tm_mday; + String currentMonth = (ptm->tm_mon + 1) < 10 ?
