  • Page 1 iCE40 UltraLite™ Breakout Board User Guide EB96 Version 1.1, March 2017 Downloaded From Oneyac.com...
  • Page 2 iCE40 UltraLite Breakout Board Introduction Thank you for choosing the Lattice iCE40 UltraLite™ Breakout Board. This guide describes how to begin using the iCE40 UltraLite Breakout Board, an easy-to-use platform for demon- strating the high-current LED drive capabilities of the iCE40 UltraLite FPGA. Along with the evaluation board and accessories, this kit includes the pre-loaded LED Driver Demo that demonstrates driving the RBG LEDs with a PWM circuit.

  • Page 4 iCE40 UltraLite Breakout Board Demonstration Design Jumpers Lattice provides the RGB LED Driver Demo design programmed in the board. The RGB LED Driver Demo used in conjunction with the software GUI illustrates the use of a PWM driver controlling the LEDs on the board. Below is a description of the control jumpers for each LED.

  • Page 5: Clock Sources

    iCE40 UltraLite Breakout Board Clock Sources The board has a single 12 MHz clock source. The 12 MHz clock drives both the FTDI USB interface device, and the iCE40UL1K device. The iCE40UL1K device can be disconnected from the 12 MHz oscillator using J16. This is nec- essary, for example, when iCE40 Ultra Lite device ball D2 is mistakenly programmed as an output and prevents the FTDI USB interface from operating.

  • Page 11 iCE40 UltraLite Breakout Board GUI Serial Communication Interface LED Control via SPI The Software GUI demonstration program communicates with the iCE40 UltraLite device using a SPI serial com- munication channel. The SPI interface (mode 0) control link is implemented using a simple write-only protocol (see Figure 10).
