1. Introduction

The Raptor™ ™Touchscreen Display is a unique offering from New Eagle. By combining a general

purpose controller and a wide array of communications with a 7-inch touch screen display on top of the Raptor™

model-based development platform, engineers with little to no programming experience have unprecedented

power to create intuitive Man-Machine Interfaces that may either directly control the host system, or

coordinate with other devices.

1.1 Motivation

Figure 1.a –The Raptor™Display Library

The purpose of this paper is to introduce the reader to the Raptor™ Touchscreen Display. A user with no

knowledge of the device should be able to put together a simple but useful application. It is assumed that the

reader has a basic understanding of Matlab, Simulink, and the Raptor™ platform.

1.2 Setup

This guide assumes some knowledge of the Raptor™ platform and model-based development with

Simulink. The minimum requirements to get started are described below:

2. Building a Model

This guide assumes that the user has installed Raptor™ with a compatible versions of Matlab and

Simulink Coder. For details about compatible versions of Matlab and Raptor™ see section 1.2.2

2.1 Getting Started

Creating a New Model

With Matlab open, enter

‘

raptor_create_touch_display_project('example_project');

’

into the

command window. Simulink should open a model like the one shown in figure 2.1.1.a.

Figure 2.1.1.a –A Template Touchscreen Display Project

Performing a Model Update (ctrl+d)

The user may validate a model without executing a full build by performing a Model Update.

This will validate parameters, connections, data types and block-specific constraints to let the user know

if a build will fail, and what can be done to prevent it.

Building a Raptor™ Touchscreen Display Model

In Simulink, a build can be triggered with ctrl+b. This will begin the task of translating blocks

placed in the model into C code and compiling them into either a PC simulator or device binary. By

default the model is configured to generate both. The simulator is useful for debugging, or doing

developing without any display hardware present. Build configuration parameters can be set in the

Target Definition block.

©New Eagle 2017 www.neweagle.net PH: 734.929.4557

Configuring the Build

There are two configuration parameters specific to the VeeCAN devices. These can be set by

opening the Target Definition block at the top of the model.

Figure 2.1.3.a –Build Configuration Settings in the Target Definition Block

Compiler

There are actually two parameters to choose for Compiler,

Device

and Simulator. If a compiler is

selected (not set to ‘none’) for device, then a device binary to program a physical VeeCAN 800 will be

generated. If a compiler for

Simulator

is selected, then the same code will be compiled and loaded into

a simulator executable.

Figure 2.1.3.b –Compiler Settings in the Target Definition Block

©New Eagle 2017 www.neweagle.net PH: 734.929.4557

Auto-Run Simulator

Checking Auto-Run

Simulator

will start the simulator executable as soon as the build is finished (if

one has been generated). Here, the user can test functionality of their display by using their mouse as if

it were their finger. You can pause, zoom, grid, and control the fps of the display. These features allow

for additional bug fixing, as well as cosmetic optimization.

Figures 2.1.3.c & d –An Example of Auto-Run Simulator

In addition to simulating the on-screen graphics, users can use a virtual CAN channel to test the

functionality of the display. Open Raptor-CAN and select the simulate tab, notice that the screen will be

blank at first. Next, choose the DBC file you want to simulate by selecting ‘Add DBC’. The messages from

the DBC file will appear, they can be expanded using the ‘+’ icon give the user access to individual signals.

To simulate the messages over the virtual CAN bus, press the play button next to the messages. From

here, the user can adjust the values by using the sliders or typing values in to the text fields on the right,

this will cause the data going into the display to change.

Programming the Display

By default, Raptor™ builds are output to the

\\ECU\

directory. After a successful build the

output should typically look like,

\\ECU\

|...|-<Project Name>\

|...|...|-<Build Number>\

|...|...|...|- README_HOW_TO_INSTALL.txt

|...|...|...|- <Project Name>_<Build Number>.zip <-- Device Binary

|...|...|...|- Simulator\

|...|...|...|...|- VeeCAN_Simulator.exe <-- VeeCAN Simulator

The contents of the build directory will vary depending on what options were selected in the

target definition block. For instance, a device binary will only be generated if a compiler was selected for

one. For more details see section 2.1.3.

Programming from a USB drive

Programming the display requires a USB flash drive. To begin reprogramming, unzip the

contents of the device binary into top level of the flash drive. (ie. so the file system on the flash drive

mirrors what is inside of the .zip file) With the display turned on, insert the flash drive into either USB

port. After a few seconds the device should detect a new program on the USB drive and begin

reprogramming. Follow the instructions on the screen to complete the process.

Figure 2.1.4.a –USB Drive Inserted in Front of a Raptor™ Display

Raptor-Cal

Raptor-Cal allows the user to program the display from a Raptor™ Package file (.rpg), as well

as connect over XCP to probe adjustment and measurement values. For more information on Raptor-Cal

go to www.neweagle.net.
