Demonstration Design
Lattice provides a pre-programmed demo to illustrate basic operation of the MachXO2280 device. The design inte-
grates an up-counter with the on-chip oscillator.
Note: You may obtain your Breakout Board after it has been reprogrammed. To restore the factory default demo
and program it with other Lattice-supplied examples see the
Run the Demonstration Design
The preprogrammed demonstration design is an up-counter to drive an LED array. The program shows a clock
generator based on the MachXO2280 on-chip oscillator. The counter module is clocked at ~22 MHz (18-26MHz) to
illustrate how low speed timer functions can be implemented with a PLD. The 23-bit up-counter further divides the
clock to advance the LED display approximately every 200ms. The resulting light pattern will appear as an alternat-
ing pair of lit LEDs per row.

WARNING: Do not connect the Breakout Board to your PC before you follow the driver installation procedure of this
section.
Communication with the Breakout Board with a PC via the USB connection cable will require the FTDI chip USB
hardware drivers contained in the
reliably recognize and program the Breakout Board. Drivers are distributed by Lattice as a stand-alone package or
with ispVM System version 17.9 or later. Use one of the two procedures below to install.
To load the FTDI chip USB hardware drivers via ispVM System:
1. Browse to
2. Install ispVM System software.
3. Run ispVM System. Choose ispTools > Install/Uninstall LSC USB/Parallel Port Driver.
4. Select FTDI USB 32-Bit Driver or FTDI USB 64-Bit Driver then click Install.
5. Click OK, then click Close from the LSC 32/64-Bit USB Drivers Install/Uninstall dialog.
6. Choose File > Exit to close ispVM System.
7. Connect the USB cable from a USB port on your PC to the board’s USB mini-B socket (J2). After connection is
