The library SparkFunBME280 contains the folowing code in SparkFunBME280.cpp:
//Constructor -- Specifies default configuration
BME280::BME280( void )
{
//Construct with these default settings if nothing is specified
//Select interface mode
settings.commInterface = I2C_MODE; //Can be I2C_MODE, SPI_MODE
//Select address for I2C. Does nothing for SPI
settings.I2CAddress = 0x77; //Ignored for SPI_MODE
//Select CS pin for SPI. Does nothing for I2C
settings.chipSelectPin = 10;
settings.runMode = 0;
settings.tempOverSample = 0;
settings.pressOverSample = 0;
settings.humidOverSample = 0;
}
Could someone please tell me how to change the value of settings.I2CAddress in my own code? By default it is set to 0x77 but my chip uses 0x76. I tried saying
bme.SensorSettings.I2CAddress = 0x76
;
(where “bme” is the object I created) but that’s apparently wrong. I understand that this is probably something really basic that any C programmer would know, but I’m not a C programmer. Thanks.
Update: Never mind. After much trial and error, I discovered the proper syntax is:
bme.settings.I2CAddress = 0x76 ;
