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)
