Feather Adalogger, BME280 and ADXL345

Other Hardware Sensors
1

Hi, I'm trying to use a Feather M0 adalogger to collect data from 3x BME280 sensors and 1xADXL345 sensor. Is this possible using I2C or should I be using SPI? Is the Feather M0 capable of using SPI and would that be a better way of getting the required data from all of these sensors? If so how might I do about connecting all those sensors together using that protocol?

I included a photo of how I've got them connected right now on a breadboard. Using the BME280_sensortest example I am getting values back from one sensors but when I use the ADXL345 example I get an error back saying no sensor found, where did I go wrong with my wiring?

This all is very new to me but something I'm interested in learning, so thank you for any/all help you guys can provide

It usually doesn't make sense to have 3 temperature/humidity/pressure sensors within the distance of a maximum length I2C or SPI bus (about 0.5m).

Post links to the libraries used!

To activate I2C mode on the ADXL345 you have to connect the CS pin to the 3V3 pin.
