Rgb Led Demonstration Design And Software Gui; Figure 10.1. Spi Flash Selection (Horizontal) For J6 - Lattice Semiconductor iCE40 UltraPlus User Manual

10. RGB LED Demonstration Design and Software GUI

The iCE40 UltraPlus Breakout Board can demonstrate a complete controller for an RGB LED. Following are the steps to
run the demonstration. The Software GUI tool used here is the same as the one used with the iCE40 Ultra Breakout
Board. You can refer to the Lattice website
To run the demonstration:
1. Ensure that the RGB LED GUI is installed.
2. Make sure the jumpers on J6 are both in the horizontal position. This is the default pins 1-3 and 2-4 shorted
together.
3. Connect the iCE40 UltraPlus breakout board via the USB cable to a PC or MAC.
4. After the iCE40 UltraPlus device has initialized and the RGB LED is illuminated RED, change the J6 jumper positions
to vertical, shorting pins 1-2 and 3-4. This is required to allow the USB port to communicate with the iCE40UP5K
device.
