Accelerometer LIS3LV02DL controlled by a dsPIC, I2C communication

This post describe the basic data acquisition of an accelerometer LIS3LV02DL over I2C bus using a dsPIC30F3012.
This tri-axial accelerometer has a 12 or 16 bit digital output and can be interfaced using SPI or I2C communication.
The circuit employed is a very simple one, The dsPIC is connected to the accelerometer LIS3LV02 via I2C using the B7 and B6 pines. The dsPIC reads the data and send the results in ascii format to the PC using the bluetooth module KC21.

Now the program and circuit to connect a dsPIC 30F3012 via serial to a PC. The serial connection is made using a Bluetooth module fro kc wirefree (R). The KC21.

The next program flashes a LED connected in the PB0 (pin 2) of a dsPIC30F3012. The chip is running at 80MHz using a crystal of 20MHz. The PLL multiplies the half of the crystal frequency by 8.
