I have a BMP280 which I am using with a Raspberry Pi Pico through an I2C connection. When I try to interact with it, it states no device found at address (0x77 or 0x76, both should work neither do). I am coding using circuitpython. My code is below:
import board
import busio
import adafruit_bmp280
i2c = busio.I2C(board.GP15, board.GP14)
#assigning bmp280 sensor
bmp280_sensor = adafruit_bmp280.Adafruit_BMP280_I2C(i2c,address=0x76)
#get temp
def read_temperature():
return bmp280_sensor.temperature
#get pressure
def read_pressure():
return bmp280_sensor.pressure
print(read_temperature())
I have been using GP14 and 15 for my I2C pins, but have tried the other I2C pins on my Pico. I am using 10k Ohm resistors for pullup. I have tried different wires and pins for both I2C pins and for ground, nothing seems to work. When I use an I2C scanner, no addresses are found. Any suggestions?
