Software Requirements
Before using the iCEstick board, download and install the latest version of Lattice iCEcube2™ and Diamond Pro-
grammer. Make sure you log in to the Lattice website, otherwise these software downloads will not be visible.
These are available at http://www.latticesemi.com/Products/DesignSoftwareAndIP.aspx. If you install Diamond
Programmer 2.2, you will require a software patch. This software patch is available at http://www.lattice-
semi.com/icestick. Go to the Downloads tab and install the appropriate patch. This patch is not required with Dia-
mond Programmer 3.0 or higher.

Communication Between the PC and iCEstick
Communication between the iCEstick Board and a PC is via the FTDI 2232H USB device. To enable this connec-
tion the installation of the FTDI chip USB hardware drivers is needed. This driver is installed when Diamond Pro-
grammer 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 demonstra-
tions.
Connecting the iCEstick Evaluation Board
Insert the iCEstick evaluation board to an open USB slot in a PC. The default bitstream in the SPI flash loads the
iCE40HX-1k device on the iCEstick board. One should see the green LED on the board light up and continue to be
lit.
Preprogrammed Design and Board LEDs
There are a total of 5 LEDs on the iCEstick board. All are controlled by I/Os of the iCE40HX-1k device. The default
bitstream loads the iCE40HX-1k device and the green LED lights up signifying that the device has loaded correctly
and power is good. The other four red LEDs arranged in a diamond pattern begins to flash in a clockwise direction.
This is the intended function of the default bitstream.
Table 1. User I/O and LEDs
Download Demo Designs
The above demo is pre-programmed into the iCEstick board. Other than the default design, Lattice also distributes
source and programming files for demonstration designs compatible with this board. To download the demo
designs:
1. Browse to www.latticesemi.com/icestick and click on the Downloads tab to view other design files and capabil-
ities that the iCEstick board could implement. Various demo designs are available and can be download.
2. Extract the contents of zip files to a local hard drive.
Lattice provides the following demos based on iCEstick board:
• UART over IrDA. In this demo design, the iCEstick device communicates with a laptop or PC through UART over
USB. Then, the payload is transmitted through Vishay IrDA device. This data can be locally looped back or
another iCEstick board could receive the data via it’s IrDA receiver.
• Diligent Pmod Accelerometer. The demo makes use of Digilent PmodAcl 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 LEDs.

IrDA Functionality and Demo
The iCEstick board has a Vishay TFDU4101 IrDA transceiver on it. This device allows transmit and receive of infra-
red data up to 115kbps.
Table 2. IrDA Pin Description
There are two possible configurations for the IrDA demo design: IrDA TX and IrDA RX. For an end to end complete
IrDA link demo, two iCEstick boards are needed, however using just the IrDA Tx design can support a demo. The
IrDA TX design transfers the data from the PC keyboard input in a terminal window to the IrDA Vishay device TXD.
While the data is transmitted via infrared, it is also by default looped back to the receive channel of the IrDA 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 4. IrDA TX on iCEstick
Laptop or PC
iCE40
IrDA TX
UART
via USB
The IrDA RX design receives infrared data from the Vishay IrDA Tx device. After the IrDA data is wirelessly
received it is then sent to the iCE40 device. The iCE40 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.

For IrDA 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 IrDA TX and the other programmed with IrDA RX,
the character typed in IrDA TX PC is transferred to and displayed on IrDA RX PC monitor. You can change the
angle of the TX board facing the RX board to see when the IrDA link would break.

Diligent Pmod Connector and Accelerometer Demo
On the iCEstick board, location J2 is a 2x6 position Pmod (Peripheral MODule) Digilent connector. The iCEstick
board supports a variety of Pmod peripheral modules for easy I/O expansion. Figure 3 lists the 0.1” 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 3. Diligent Pmod Compatible Connector Description
The Accelerometer demo makes use of the Digilent PmodAcl accelerometer module from Diligent. The PmodAcl
module needs to be plugged into J2 on the iCEstick board through the cable that comes with this module. The four
LEDs D1, D2, D3 and D4 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 LEDs on the iCEstick board goes on/off corresponding to the direction of the movement and orientation of
the module. If all these LEDs light up at the same time (indicating a balance point), The D5 LED also lights up.

Expansion I/O Connections
The iCEstick board contains two unpopulated 0.1” headers for users to implement their own connections. Connec-
tors J1 and J3 each consist of 10 positions for a total of 20 connections. Two of these are tied to 3.3v and two are
tied to ground. This leaves 16 general purpose I/Os that connect to the iCE40HX-1k device for user I/O.
Table 4. Expansion I/O Connections
Test Points
There are three unpopulated test points. TP1 is tied to 3.3v, TP2 is tied to 1.2v and TP3 is connected to ground.
