1. Overview

Congratulations on your purchase of the New Eagle VeeCAN320L EV Supervisor Display! This rugged CAN bus display solution is easy to integrate into your EV system. The display’s casing is environmentally sealed to IP67 rating, and the 320*240 pixel LCD panel is viewable in direct sunlight. It is already configured to display fundamental EV parameters, such as battery SOC, motor speed, drive mode, and faults. This product includes a MotoHawk application library, which allows the developer to integrate the proper CAN messaging into the EV Supervisor model to interact with the display. Please continue reading to learn more about the display’s capabilities.

1.1 Kit Contents

The kit includes:

- Pre-programmed VeeCAN320L (ASM-DISP-MH-EV-01) - MotoHawk display app (MH-DISP-EV-AP-01) to integrate in existing EV software - Pigtail or display to SmartCraft harness (optional)

2. Setup

2.1 Hardware Setup

The display is ready to use out of the box. It will require battery power, ground, and CAN to operate properly. All of these pins can be located on the primary connector. Here are the required connections for operation.

Pin number Function

1 Ground

2 Power (10-32V DC)*

7 CAN1-

8 CAN1+

*Supply should be protected by 500mA rated circuit breaker/fuse

Please see Hardware Specifications for more connector information.

2.2 Software Setup

The display comes with a pre-programmed application library to facilitate easy integration with systems being developed on the MATLAB/MotoHawk platform. In order to communicate with the display, the CAN bus speed must be set to 250kbaud. Please see Display Application Library for more information.

To customize the splash screen, go to New Eagle’s wiki site: http://www.neweagle.net/support/wiki/index.php?title=EV_Components#Embedded_Displays

Download splash_update.zip, unzip the folder, and place its contents into a USB stick. The new image should be named splashscreen.bmp, and should be a 320x240 24-bit .bmp image. Plug the USB stick into the display while it is powered on. The display will automatically begin updating the

4. Display Application Library

In your MotoHawk model, include a CAN definition block configured for 250 kbaud. For each display library block, there is a dialog box that allows you to add the name of the desired CAN bus, as indicated in your CAN definition.

4.1 Battery Parameters

The Battery Status screen is accessible by pressing the middle button of the display. In your MotoHawk EV application model, connect the model signals for State of Charge, State of Health, Maximum Battery Temperature, Battery Voltage, and Battery Current to their corresponding inputs of the VeeCAN320L EVS Display library block, as seen below.



4.2 Motor Parameters

The Motor Status screen is accessible by pressing the second-to-left button of the display. In your MotoHawk EV application model, connect the model signals for Motor Power, Drive Current, Motor Speed, and Motor Torque to their corresponding inputs of the VeeCAN320L EVS Display library block, as seen below.



4.3 PCM Parameters

The PCM Status screen is accessible by pressing the second-to-right button of the display. In your MotoHawk EV application model, connect the model signals for Motor Not Healthy, Motor Temperature, IGBT Temperature, and Inverter Voltage to their corresponding inputs of the VeeCAN320L EVS Display library block, as seen below. Please be aware that the Motor Not Healthy message does not appear on the screen until the fault is set.



4.4 SOC Parameters

The State of Charge screen is accessible by pressing the left-most button on the display. In your MotoHawk EV application model, connect the model signal for State of Charge to its corresponding inputs of the VeeCAN320L EVS Display library block, as seen below.



4.5 Vehicle Parameters

The vehicle parameters are accessible throughout the whole display. In your MotoHawk EV application model, connect the model signals for Drive Mode, Hand Brake State, System State (Initializing or Ready), Accessory Mode, and other warning signals to their corresponding inputs of the VeeCAN320L EVS Display library block, as seen below. Please note that when an input signal is set to Boolean 1, that particular parameter will show on the screen.



4.6 Fault Handler

The Faults Display screen is accessible by pressing right-most button of the display. To use the Fault Display Handler, the model must contain a MotoHawk OBD fault manager, at least TWO MotoHawk OBD fault definitions, and a run time variable (time must be in seconds and data type must be uin32). To list all OBD faults, use the function motohawk_get_obdfaults. Otherwise, the user can choose individual faults by creating a list from the existing OBD fault definitions (e.g. {‘myFlt1’, ‘myFlt2’, ‘myFlt3’}).

To display different fault names (instead of using the names in the OBD fault definitions), you may use a custom faults list. The OBD fault names are listed in alphabetical order, therefore the custom fault list should be ordered appropriately.



The Faults Display screen shows all the faults sent by the Fault Display Handler. The up and down arrow buttons scroll through the list of faults, and the History/Active button toggles between displaying active and occurred faults. The center button acknowledges currently active faults, which are shown in red until acknowledged. Once an active fault has been acknowledged, it will remain as such until the fault changes state and then becomes active again.

4.7 Vehicle Run Time Example

This block contains sample code of the vehicle run time to be used with the Fault Display Handler. The vehicle run time variable name should match the name used in the Fault Handler block.

It is the user’s responsibility to execute a proper control strategy to achieve the desired outputs. New Eagle is not responsible for improper implementation of control.
