MPU-6050 Test Design

This FPGA design displays the accelerometer, gyroscope and temperature readings from a MPU-6050 chip on a PC connected to the XuLA2 + StickIt! + StickIt! MPU-6050 board combination.

Important Files

MPUTest.vhd: Master module that reads the MPU-6050 sensors and reports them back to the PC.

HostIoToI2c.vhd: Module that allows commands and data to flow between the PC's USB port and the I2C port of the MPU-6050 via the FPGA.

I2c.vhd: Master-mode I2C interface from OpenCores.org.

MPUTest-XuLA2.ucf: Pin assignments for connecting the XuLA2 FPGA board to the StickIt! DIPSwitch module via the StickIt! motherboard. (If you are using a XuLA board, then use the MPUTest-XuLA.ucf file, instead.)

MPUTest.xise: The Xilinx ISE project file that ties all the previous files together.

MPUTest.py: A Python file that establishes communication with the XuLA board and repeatedly reads and displays the MPU-6050 sensors as hexadecimal numbers. (Use pip install xstools or easy_install xstools to install the Python packages that will make this program work.)

Running the Test

  1. Load the .xise project file with ISE and compile it into a .bit file.
  2. Insert a XuLA2 board into a StickIt! motherboard.
  3. Attach a StickIt! MPU-6050 module to the PM6 connector of the motherboard.
  4. Attach a USB cable to the XuLA2 board. (This will supply power for the entire collection of boards and modules.)
  5. Use XSLOAD or GXSLOAD to download the .bit file to the FPGA on the XuLA board.
  6. Run the command python MPUTest.py to start the polling of the MPU-6050. The sensor readings will be displayed on the PC as hexadecimal numbers.
