These are the parts
First enable i2c and download tools. By following the directions here.
Once this is done we can check for devices using:
sudo i2cdetect -y 1
My result shows i2c devices on 2A, 68 and 77.
- 0x77 is the BME280 pressure/temperature/humidity sensor it can be 0x76 if you add a jumper
- 0x68 is the MPU-6050 which has the HMC5883L as a slave
- 0x2A is the FLIR Lepton
First I am going to work on getting the pressure/temperature sensors to work. I have two sensors for this:
BME280 - Pressure, humidity and temperature
BMP180 - Pressure and temperature data included on GY-87 board
I will use the Adafruit BME280 driver for python which depends on Adafruit GPIO library.
After following the instructions to get everything installed. I can read the temperature and pressure from my BME280. I had to change a line in Adafruit_BME280.py so that I could use my BME280 on i2c 0x76 instead of the default 0x77.
Now I am ready to try out the IMU sensors.
