3 icestick Evaluation Kit Introduction Thank you for choosing the Lattice Semiconductor icestick Evaluation Kit. This guide describes how to start using the icestick Evaluation Kit, an easy-to-use US form factor board for rapidly prototyping designs using the ice FPG. long with the evaluation board, this kit includes a pre-loaded design that demonstrates basic board functionality. The contents of this user s guide include demo operations, descriptions of the various portions of the evaluation board, descriptions of the on-board connectors, a complete set of schematics and bill of materials for the icestick Evaluation oard. Features The icestick Evaluation Kit includes: icestick Evaluation oard features the following on-board components High-performance, low-power icehxk FPG FTI H US device allows ice device programming and URT interface to a PC Vishay TFU Ir transceiver Five user LEs x 6 position iligent Pmod TM compatible connector enables many other peripheral connections iscera Mhz MEMS oscillator Micron Mbit NQ SPI flash Supported by Lattice icecube design software US connector provides the power supply 6 LVCMOS/LVTTL (.V) digital I/O connections on. through-hole connections Pre-loaded demo design the kit includes the pre-loaded demo design that flashes the on-board LEs in a clockwise pattern.

5 Software Requirements icestick Evaluation Kit efore using the icestick board, download and install the latest version of Lattice icecube and iamond Programmer. Make sure you log in to the Lattice website, otherwise these software downloads will not be visible. These are available at If you install iamond Programmer., you will require a software patch. This software patch is available at Go to the ownloads tab and install the appropriate patch. This patch is not required with iamond Programmer. or higher. Figure.

6 Communication etween the PC and icestick icestick Evaluation Kit Communication between the icestick oard and a PC is via the FTI H US device. To enable this connection the installation of the FTI chip US hardware drivers is needed. This driver is installed when iamond Programmer was installed. These drivers enable the computer to recognize and program the icestick board. In addition these drivers allow communication between the PC and the icestick board to enable further demonstrations. Connecting the icestick Evaluation oard Insert the icestick evaluation board to an open US slot in a PC. The default bitstream in the SPI flash loads the icehx-k device on the icestick board. One should see the green LE on the board light up and continue to be lit. Preprogrammed esign and oard LEs There are a total of LEs on the icestick board. ll are controlled by I/Os of the icehx-k device. The default bitstream loads the icehx-k device and the green LE lights up signifying that the device has loaded correctly and power is good. The other four red LEs arranged in a diamond pattern begins to flash in a clockwise direction. This is the intended function of the default bitstream. Table.

Other than the default design, Lattice also distributes source and programming files for demonstration designs compatible with this board. To download the demo designs:. rowse to and click on the ownloads tab to view other design files and capabilities that the icestick board could implement. Various demo designs are available and can be download.. Extract the contents of zip files to a local hard drive. Lattice provides the following demos based on icestick board: URT over Ir. In this demo design, the icestick device communicates with a laptop or PC through URT over US. Then, the payload is transmitted through Vishay Ir device. This data can be locally looped back or another icestick board could receive the data via it s Ir receiver. iligent Pmod ccelerometer. The demo makes use of igilent Pmodcl module which is plugged into icestick board. In this demo design, the accelerometer setting and reading is done by the on-board ice device and the direction of movement is displayed with the diamond pattern LEs.

7 Ir Functionality and emo icestick Evaluation Kit The icestick board has a Vishay TFU Ir transceiver on it. This device allows transmit and receive of infrared data up to kbps. Table. Ir Pin escription Ir function CPL pin CPL I/O Comment RX 6 PIO_9 Receive data pin TX PIO_8 Transmit data pin S 7 PIO_ Shut down There are two possible configurations for the Ir demo design: Ir TX and Ir RX. For an end to end complete Ir link demo, two icestick boards are needed, however using just the Ir Tx design can support a demo. The Ir TX design transfers the data from the PC keyboard input in a terminal window to the Ir Vishay device TX. While the data is transmitted via infrared, it is also by default looped back to the receive channel of the Ir device. In this demo the looped back data is received and before it is transmitted to the PC window the text is converted from lower case to upper case. This is the signal flow for the stand alone demo. Figure. Ir TX on icestick URT via US ice Ir TX Laptop or PC The Ir RX design receives infrared data from the Vishay Ir Tx device. fter the Ir data is wirelessly received it is then sent to the ice device. The ice then send the character information to the open window on the PC. Thus whatever is typed in the TX terminal window is displayed in the Rx terminal window. Figure. Ir RX on icestick URT Over US ice Vishay Ir Laptop or PC This demo requires a terminal program on PC to communicate with the icestick board. The following instructions describe the setup for Ir TX stand alone demo using the Tera Term terminal emulator program on Windows 7. 6

Check if the US driver is installed correctly. Go to Start, right-click Computer and select Properties. The System window is shown. Click evice Manager. Figure 6. System Window. If the driver is installed correctly, the device is listed without an error tag under Ports (COM & LPT) as shown in Figure 7. Proceed to the next step. Figure 7. evice Manager 7

9 icestick Evaluation Kit If the driver is not installed correctly, the device is tagged with a yellow exclamation point as shown in Figure 8. You need to install the driver. To do this, right-click the device and select Update river Software. Figure 8. evice Manager with river Error Request Windows to search the web for the driver. fter Windows locates the FTI driver, install it and proceed to the next step.. Install Tera Term software. The installer can be downloaded from _ html. 6. Open Tera Term. 7. In the New connection dialog box, click Serial. 8. On the Port menu, click COMxx: US Serial Port (COMxx). If there are two or more options, select the last COM port on the list. Click OK. Figure 9. New Connection ialog ox 9.

Figure. Terminal Setup ialog ox When you type in the Tera Term VT window using the TX design, a lower case character is echoed with a capital character from the ice device as shown in the Figure.

12 icestick Evaluation Kit Figure. Tera Term VT Window Using TX esign For Ir RX, the above Tera Term setting is the same but the bitstream for the ice device is different. With a setup of two icestick boards facing each other, one programmed with Ir TX and the other programmed with Ir RX, the character typed in Ir TX PC is transferred to and displayed on Ir RX PC monitor. You can change the angle of the TX board facing the RX board to see when the Ir link would break.

13 iligent Pmod Connector and ccelerometer emo icestick Evaluation Kit On the icestick board, location J is a x6 position Pmod (Peripheral MOule) igilent connector. The icestick board supports a variety of Pmod peripheral modules for easy I/O expansion. Figure lists the. through-hole headers on the icestick board that support Pmod modules. Pmod modules come in different form factors, and each Pmod header includes power and ground supplies. The easiest way to support a Pmod module is to add the appropriate female socket. Straight-through or right-angle connectors can be used. Male headers are an alternate solution when using the interface cable provided with most Pmod modules. Table. iligent Pmod Compatible Connector escription Connection Left Row pins Right Row pins Connection PIO_ 7 PIO_6 PIO_ 8 PIO_7 PIO_ 9 PIO_8 PIO_ PIO_9 Ground Ground The ccelerometer demo makes use of the igilent Pmodcl accelerometer module from iligent. The Pmodcl module needs to be plugged into J on the icestick board through the cable that comes with this module. The four LEs,, and in the north, south, east and west pattern are configured to represent X+, Z+, X-, Z- of accelerometer movement direction respectively. When the accelerometer module is moved around, the diamond pattern LEs on the icestick board goes on/off corresponding to the direction of the movement and orientation of the module. If all these LEs light up at the same time (indicating a balance point), The LE also lights up. Figure. ccelerometer emo on icestick.v 6.v cl Module ice LE ccelerometer emo on icestick
