Project Setup
This project is based on the MicroZed board with I/O carrier card. The FPGA hardware and the console application will be
loaded via micro SD card.
You will need:
• MicroZed board
• I/O carrier card
• KMA36 sensor for Digilent Pmod™ board
• Micro SD card
• I/O carrier card power adapter
• USB-to-MicroUSB cable for UART communications
• A computer with a card reader to write to the SD card and to host a terminal emulator
The following steps will guide you through setting up the hardware platform:
1. First, if you have not connected your computer to a ZedBoard or MicroZed device before, you will likely need to download
and install the Silicon Labs CP2104 USB-to_UART driver. The setup guide for installing the driver can be found at the
address below: http://www.zedboard.org/sites/default/files/documentations/CP210x_Setup_Guide_1_2.pdf
2. Next, attach the SD card to your computer via a card reader or through the built-in SD card slot. Download the “boot.bin”
file that pertains to the KMA36 from the MicroZed software link and copy it onto the SD card so that it is the only file
present on the file system.
3. Safely eject the micro SD card from your computer. Insert the micro SD card into the card slot on the back of the MicroZed
board.

4. Carefully line up the MicroZed board with the I/O carrier card and push them together until snug.
5. Connect the KMA36 digital magnetic encoder sensor to the “JC” Digilent Pmod™ port of the I/O carrier card, ensure that
jumpers J1, J2, and J3 are configure such that the MicroZed will boot from the SD card on start up, and connect the power
adapter to the barrel jack on the I/O carrier card (shown on the right). Finally connect the micro-USB cable to the micro-
USB port of the MicroZed (shown at the left). The USB cable will facilitate UART transmissions for the console application.
6. Turn on the power to the board with the switch next to the barrel jack. When the board powers up, the MicroZed will briefly
illuminate a red LED, which will then turn off after less than a second. Once the FPGA has been successfully programmed
by the boot image on the SD card, a blue “Done” LED will illuminate on both the MicroZed and the I/O carrier card. Your
hardware should appear as shown below. If the board was powered on before this step, turn the power off and repeat this
step.

Launching the Console Application
Now that you have successfully set up your hardware platform, you are ready to run the console application.
1. Upon power-on, the console application should already be running. It will be necessary to open a terminal and configure
a serial connection to interact with the console application. Do this by opening tera term (which can be downloaded from
http://en.sourceforge.jp/projects/ttssh2/releases/) or a similar terminal emulation software package.
2. Tera Term may display an error when it starts up if it tries to connect to a COM port where no device is present. It is safe
to ignore this warning, so click OK. Next, open the “Setup” menu and click the “Serial Port…” option.
3. Safely eject the micro SD card from your computer. Insert the micro SD card into the card slot on the back of the
MicroZed board.

4. Carefully line up the MicroZed board with the I/O carrier card and push them together until snug.
5. Connect the KMA36 digital position sensor to the “JC” Digilent Pmod™ port of the I/O carrier card, ensure that jumpers
J1, J2, and J3 are configure such that the MicroZed will boot from the SD card on start up, and connect the power adapter
to the barrel jack on the I/O carrier card (shown on the bottom). Finally connect the micro-USB cable to the micro-USB
port of the MicroZed (shown at the top). The USB cable will facilitate UART transmissions for the console application.
6. Turn on the power to the board with the switch next to the barrel jack. When the board powers up, the MicroZed will
briefly illuminate a red LED, which will then turn off after less than a second. Once the FPGA has been successfully
programmed by the boot image on the SD card, a blue “Done” LED will illuminate on both the MicroZed and the I/O carrier
card. Your hardware should appear as shown below. If the board was powered on before this step, turn the power off and
repeat this step.

7. Now select the appropriate COM port that your MicroZed setup is connected to. If you are not sure which this is, refer to
the Device Manager. Configure your serial connection with 115200 Baud, 8 bit data, no parity, 1 stop bit, and no flow
control, and then click OK.
8. You should now have a live connection open to the console application running on the MicroZed. Press enter and the
console application will display the main menu from which you can perform several tasks on the KMA36 digital magnetic
encoder sensor.

Running the Console Application
The console application is intended to demonstrate the required operations when using the sensor.
a. The KMA36 software must have an I2C address set or it may not function. Do this by selecting (1) and selecting the
correct address BEFORE performing any other options.
Now the sensor and the software are setup and ready to use. This first step only needs to be performed at power up.
a. The console application option (2) reads the magnetic rotation in degrees and displays it to the console.
b. The console application option (3) sends the I2C command to enter the KMA36 into sleep mode.
c. The console application option (4) sends the I2C command to exit sleep mode.
d. The console application option (5) sends the I2C command to enable low power mode.
e. The console application option (6) sends the I2C command to disable low power mode.
f. The console application option (7) sends the I2C command to enable counter.
g. The console application option (8) sends the I2C command to disable counter.
h. The console application option (9) sends the I2C command to enable fast rate.
i. The console application option (0) sends the I2C command to disable fast rate.
j. The console application option (A) displays a menu which allows the user to select from one of four possible over-
sampling rates.
k. The console application option (B) displays a prompt for the user to enter an integer between 1 and 32767 to be written to
the KMA36’s 16-bit resolution register.
