Hey Guys, So I have a MMA7455L accelerometer (Data Sheet) <http://www.parallax.com/sites/default/files/downloads/28526-Freescale-MMA7455L-Device-Documentation.pdf> and hooked it up to the Beaglebone black via I2C. To test that I could read the registers I used the linux I2C tools. I used the following command to display the values from the registers:
*sudo i2cdump 1 0x1d* By using this command I should get a table with different values pertaining to different registers. Unfortunately, here is my result: <https://lh4.googleusercontent.com/-eMkyN4M99jQ/U-uyN3J5wrI/AAAAAAAAARU/fubdNThL1RA/s1600/Screen%2BShot%2B2014-08-13%2Bat%2B11.44.37%2BAM.png> According to the data sheet the following registers should contain their corresponding pieces of information: x06 => 8 bit value for x x07 => 8 bit value for y x08 => 8 bit value for z But they are not there. As you have probably noticed, I do get the following values: x0d => I2C Device Address x0e => User Information x0f => Who am I value Does anybody know why I am not getting any information in x06...etc. ? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
