Pin connections from Nova to BME280
- Nova IO0 to CS
- Nova IO2 to SDO
- Nova IO3 to SCK
- Nova IO4 to SDI
- Nova 3V3 to VIN
- Nova GND to GND
Example code:
This example uses Adafruit’s digitalio package to create a DigitalInOut object for the Chip Select Pin and the busio package to create an SPI object.
import time
import board
import digitalio
import busio
import adafruit_bme280
# Create library object using our Bus SPI port
spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
bme_cs = digitalio.DigitalInOut(board.IO0)
bme280 = adafruit_bme280.Adafruit_BME280_SPI(spi, bme_cs)
# change this to match the location's pressure (hPa) at sea level
bme280.sea_level_pressure = 1013.25
while True:
print("\nTemperature: %0.1f C" % bme280.temperature)
print("Humidity: %0.1f %%" % bme280.humidity)
print("Pressure: %0.1f hPa" % bme280.pressure)
print("Altitude = %0.2f meters" % bme280.altitude)
time.sleep(2)
