This project shows you how to use I2C to communicate with BMP180/ BMP280 Barometric Pressure Sensors. This project supports multiple I2C slave devices. The data from sersor is filtered to remove noise and glitch. This is an option to use my filter or a simple Kalman filter.
The filtered pressure value is then used to make musical notes, via on-broard synthesizer with DAC or via PC's MIDI synthesizer. See the demo video: pressure_to_sound.mp4
Hardware
- Texas Instruments Tiva C Series TM4C123G LaunchPad
- BMP180 or BMP280 barometric pressure sensors
- USB Cable, of course
Software
- Install TI's Code Composer Studio
- Install TivaWare for C Series
- Include your Tivaware folder into project, you can use the macro TI_TIVAWARE_ROOT in vars.ini
- Change the heap size as you want
- To use ROM_function() you must define part number of this kit TARGET_IS_TM4C123_RB1
- You can flash to the board via CCS or TI's LM Flash Programmer
