Topic: How to use BMA180 breakout board (Read 506 times) previous topic - next topic

Hey I am a beginner and i want to use BMA180 breakout board. There are other 5V devices which need to be used simultaneously along with it and BMA180 requires 3.3V signals.  Any help with wiring and code for getting orientation values will be helpful. I am not experienced in I2C either

I have tried the cardinfo example an it is not being initialized. The one time it did initialize it said card format is not compatible. I used a formatted 1gb MMC

I used 1.8K and 3.3K voltage divder for converting signals to 3.3V for the MMC card breakout.

The wiring i followed for bma180 is
