Project Setup You will need: * MicroZED board * I/O Carrier Card * MS8607 Sensor * 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 of MicroZED device before, you will likely need to download and install the Silicon Labs CP2104 USB-toUART 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 MS8607 from the MicroZed Software link and copy it onto the SD card so that it is the only file present on the file system. SENSOR SOLUTIONS /// MS8607 MICROZED SOFTWARE DEVELOPMENT KIT Page 3 MS8607 MicroZed Driver 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 MS8607 Digital Pressure and Humidity Sensor to the "JC" 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. SENSOR SOLUTIONS /// MS8607 MICROZED SOFTWARE DEVELOPMENT KIT Page 4 MS8607 MicroZed Driver 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 t he 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. SENSOR SOLUTIONS /// MS8607 MICROZED SOFTWARE DEVELOPMENT KIT Page 5 MS8607 MicroZed Driver 3. 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. SENSOR SOLUTIONS /// MS8607 MICROZED SOFTWARE DEVELOPMENT KIT Page 6 MS8607 MicroZed Driver 4. 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 MS8607 digital temperature sensor. Running the Console Application The console application is intended to demonstrate the required operations when using the sensor. A. After startup, it is a good idea to reset the sensor. This puts it in a known state. Do this by selecting (1) in the consol e application. B. Each sensor is tested at the factory to determine the variation of the sensor due to fabrication. Calibration coefficients are st ored in the device at that time for later use in calculating the correct output. These coefficient values must be read from the d evice and stored in software variables before measurements can be taken. Do this by selecting (2) in the console application. Now the sensor and the software are setup and ready to use. These first two steps only need to be performed at power up. C. The console application option (3) displays a menu that allows the user to select from the four possible humidity resolution modes of the sensor. D. The console application option (4) displays a menu that allows the user to select from the six possible pressure over-sampling resolution modes of the sensor. E. The console application option (5) reads the temperature, pressure, and relative humidity values and displays each of them once. F. The console application option (6) reads the temperature, pressure, and relative humidity 20 times each at approximately two measurement triplets per second and displays them to the screen in real time. G. The console application option (7) computes the dew point from the last measured temperature and relative humidity values. H. The console application option (8) reads the MS8607's battery status and displays it to the console. I. The console application option (9) reads the MS8607's heater status and displays it to the console. J. The console application option (0) sends the I C command to the MS8607 device that enables the on-chip heater. K. The console application option (A) sends the I C command to the MS8607 device that disables the on-chip heater. 2 2 SENSOR SOLUTIONS /// MS8607 MICROZED SOFTWARE DEVELOPMENT KIT Page 7 MS8607 MicroZed Driver Application Code This section is intended to provide a basic example of functionality. /* * Copyright (c) 2009-2012 Xilinx, Inc.
