In my first trial with accelerometers, I just want to get a "Hello World" from an MMA8652 via I2C mastered from a MSP430G2553 which is into the ti launchpad (not Arduino). I've searched for information in the web and tried lots of examples but never got a response from the accelerometer.
In particular I took the examples for I2C communication that come with the Code Composer Studio, changing the slave address to the WHO_AM_I address (UCB0I2CSA = 0x0d) and I've also tried to read several other adresses.
Many blogs mention i2c.h library, but I couldn find it specifically for G2553 microprocessor, the examples into CCS don't use it. I've also read about wire.h, but I understand it is for Arduino board.
I've tried Mr. Kerry Wong examples, etc, etc, etc ...
I used two accelerometers in two different boards and nothing, I don't actually know if they are alive.
Please I'm asking for a very basic working code example which gets a response from the accelerometer.
You can see into the image how I've connected the accelerometer to the launchpad (it is ok VCC=3.56V ?)
On the other hand I know that MSP430G2553 is working ok because I succesfully communicated it via i2c with other MSP430G2553.
