Installation

• The library can be found by the name ** gyverbme280 ** and installed through the library manager in:
  • Arduino ide
  • Arduino ide v2
  • Platformio
• [download library] (https://github.com/gyverlibs/gyverbme280/archive/refs/heads/main.zip). Zip archive for manual installation:
  • unpack and put in * C: \ Program Files (X86) \ Arduino \ Libraries * (Windows X64)
  • unpack and put in * C: \ Program Files \ Arduino \ Libraries * (Windows X32)
  • unpack and put in *documents/arduino/libraries/ *
  • (Arduino id) Automatic installation from. Zip: * sketch/connect the library/add .Zip library ... * and specify downloaded archive
• Read more detailed instructions for installing libraries [here] (https://alexgyver.ru/arduino-first/#%D0%A3%D1%81%D1%82%D0%B0%BD%D0%BE%BE%BE%BED0%B2%D0%BA%D0%B0_%D0%B1%D0%B8%D0%B1%D0%BB%D0%B8%D0%BE%D1%82%D0%B5%D0%BA)

Update

• I recommend always updating the library: errors and bugs are corrected in the new versions, as well as optimization and new features are added
• through the IDE library manager: find the library how to install and click "update"
• Manually: ** remove the folder with the old version **, and then put a new one in its place.“Replacement” cannot be done: sometimes in new versions, files that remain when replacing are deleted and can lead to errors!

initialization

`CPP Gyverbme280 BME; `

Usage

`` `CPP Bool Begin (VOID);// Launch with a standard address (0x76) Bool Begin (Uint8_T Address);// Launch addressing the address Bool ISMEASURING (VOID);// returns True while the measurement is underway Float Readpressure (Void);// Read the pressure in PA Float Readhumidity (VOID);// read humidity in % VOID OneMeasurement (VOID);// make one dimension and go into a dream Float ReadTemperature (VOID);// Read the temperature in degrees with

VOID setmode (uint8_t mode);// set the operating mode // modes: Normal_Mode Forced_Mode

VOID SetFilter (Uint8_t Mode);// Change the filtration coefficient.Call before Begin // coefficients: Filter_disable Filter_coEF_2 Filter_coEF_4 Filter_coEF_8 Filter_coEF_16

VOID SetstandbyTime (Uint8_t Mode);// Change the time between measurements.Call before Begin // modes: Standby_500us Standby_10ms Standby_20ms Standby_6250us Standby_125MS Standby_250MS Standby_500ms Standby_1000ms

VOID sethumoversampling (Uint8_t Mode);// Configure oversemling or turn off humidity.Call before Begin VOID settempoVersampling (Uint8_t Mode);// Configure oversemling or turn off the temperature.Call before Begin VOID SetPressoversampling (Uint8_t Mode);// configure oversemling or disconnect dCranberry.Call before Begin // modes: Module_disable Oversampling_1 Oversampling_2 Oversampling_4 Oversampling_8 Oversampling_16 `` `

Example

The rest of the examples look at ** Examples *! `` `CPP / A simple example, demonstrating the basic functions of measuring temperature, pressure and humidity */

#incLude <gyverbme280.h> // Library connection Gyverbme280 BME;// Creating a BME Object

VOID setup () { Serial.Begin (9600);// launch of the sequential port bme.begin ();// if additional.Settings are not needed - initialize the sensor }

VOID loop () { Serial.print ("Temperature:"); Serial.print (BME.Readtemperature ());// We display the temporary core in [*c] Serial.println (" *c");

Serial.print ("Humidity:"); Serial.print (bme.readhumidity ());// We display humidity in [%] Serial.println (" %");

Float Pressure = Bme.Readpressure ();// read pressure in [pa] Serial.print ("Pressure:"); Serial.print (Pressure / 100.0F);// Removing pressure in [GPA] Serial.print ("hpa,"); Serial.print (Pressuretommhg (Pressure));// Removing the pressure in [mm RT.pillar] Serial.println ("MM HG"); Serial.print ("altitide:"); Serial.print// We display height B [m above the ur.seas] Serial.println ("m"); Serial.println (""); DELAY (1000); } `` `

versions

• V1.3 - Fixed error when ledge.temperature
• v1.4 - divided into h and CPP
• V1.5 - Added BMP280 support

bugs and feedback

Create ** Issue ** when you find the bugs, and better immediately write to the mail [alex@alexgyver.ru] (mailto: alex@alexgyver.ru) The library is open for refinement and your ** pull Request ** 'ow!

When reporting about bugs or incorrect work of the library, it is necessary to indicate:

• The version of the library
• What is MK used
• SDK version (for ESP)
• version of Arduino ide
• whether the built -in examples work correctly, in which the functions and designs are used, leading to a bug in your code
• what code has been loaded, what work was expected from it and how it works in reality
• Ideally, attach the minimum code in which the bug is observed.Not a canvas of a thousand lines, but a minimum code
