BME280

[denzel 0]

i'have hooked up a bme280 sensor to msp430.

I have tried serveral libraries, https://github.com/finitespace/BME280/ and https://github.com/adafruit/Adafruit_BME280_Library.

Though am running into the same error.

error: 'NAN' has not been declared
error: 'NAN' has not been declared

What could be the issue? 

Regards.

What MSP430 are you using?  SPI or I2C (just saw you tagged it I2C)?

If you look in Adafrauit's Adafruit_BME280.cpp file under lines 374, 403, and 437 - there is the following 'if' statement,

int32_t adc_T = read24(BME280_REGISTER_TEMPDATA);
	if (adc_T == 0x800000) // value in case temp measurement was disabled
	return NAN;

NAN simply refers to 'not a number', and indicates typically something went wrong when reading the sensor. Adafruit's example was originally written for Arduino, so you'll have to use something similar for NAN in Energia I assume.

Have a look at SensorsWeather_Library, available through the Library Manager on Energia.

The Weather Sensors Library supports the

• TMP007 infra-red thermometer,
• OPT3001 light sensor, and
• BME280 thermometer, barometer and hydrometer

of the Sensors BoosterPack.

In addition, I succesfully used this one : http://cactus.io/hookups/sensors/barometric/bme280/hookup-arduino-to-bme280-barometric-pressure-sensor

I just made some modifications to get sensor working in low power mode.

Hello all,

I am working to CC3200 launchpad and i want to interface bme680 sensor with CC3200 using Energia IDE. I am searching for library of this sensor but couldn't fine one. Can anyone help me regarding this? I tested this sensor with arduino uno and esp32  and adafruit_bm680 library works fine. but i tried to run it on energia and it didn't worked. Please guide me regarding this thanks.
