Himax HM01B0 UPduino Shield Based Hand Gesture Detection Demo
User Guide

1. Introduction

The Lattice Himax HM01B0 UPduino Shield Based Hand Gesture Detection Demo User Guide describes how to operate
the Hand Gesture demo on the Himax HM01B0 UPduino Shield board. This design features a Convolutional Neural
Network (CNN), using the Compact CNN Accelerator soft IP, which is used in hand gesture.

2. Functional Description

In this demo, there are three LED lights with potential to turn on. The bottom LED represents a detected open hand,
middle LED represents a detected closed hand, and top LED represents everything else.
Figure 2.1 shows the diagram of the Hand Gesture demo. The camera captures the image data and sends it to the iCE40
UltraPlus device. iCE40 UltraPlus then uses the image data with the firmware file from the external SPI Flash to
determine the three outcomes.

3. Demo Setup

Before running the demo, make sure that the two boards are properly connected. A micro USB is required for
programming and to turn on the board.
Important: Make sure that the protective film is removed from the camera sensor.
