Happy simulating!
Connect the pin of the BMP280 to the Arduino A5 (SCL) pin.
Most custom Proteus models default to the I2C interface because it requires fewer pins. Wire the components as follows: bmp280 proteus library
#include #include Adafruit_BMP280 bmp; // Uses I2C interface void setup() Serial.begin(9600); Serial.println(F("BMP280 Simulation Test")); // Initialize the sensor; change address to 0x76 if 0x77 fails if (!bmp.begin(0x76)) Serial.println(F("Could not find a valid BMP280 sensor, check wiring!")); while (1); void loop() // Read and print Temperature data Serial.print(F("Temperature = ")); Serial.print(bmp.readTemperature()); Serial.println(" *C"); // Read and print Barometric Pressure data Serial.print(F("Pressure = ")); Serial.print(bmp.readPressure() / 100.0F); // Convert Pascals to hPa Serial.println(" hPa"); // Read and print Estimated Altitude data Serial.print(F("Approx Altitude = ")); Serial.print(bmp.readAltitude(1013.25)); // 1013.25 is sea level pressure Serial.println(" m"); Serial.println(); delay(2000); Use code with caution. 6. Running the Simulation
Simulating a BMP280 sensor in Proteus offers several compelling advantages over physical prototyping:
Since Proteus cannot read raw .ino sketches, you must compile the code into a binary format. In the Arduino IDE, go to -> Export Compiled Binary . This creates a .hex file in your project directory. Running and Debugging the Simulation Connect the pin of the BMP280 to the Arduino A5 (SCL) pin
If using Arduino-compatible libraries, your code might look like this example from the BMP280Emulator project:
Start the simulation. Open the (or Serial Monitor in Proteus) – you should see temperature, pressure, and altitude values.
void loop() Serial.print("Temperature = "); Serial.print(bmp.readTemperature()); Serial.println(" *C"); void loop() Serial.print("Temperature = ")
A comprehensive BMP280 Proteus library should include the following features:
