Getting Started with the ASL5015EVBSLAV

2.1 Board Overview

ASL5015EVBSLAV features the ASL5015SHN. The ASL5xxxyHz family is a fully featured and flexible Matrix LED Controller (MLC). It provides a cost-effective design solution, specifically targeting advanced automotive exterior lighting applications. Smart PWM part numbers determine PWM dimming duty cycle from information stored inside the MLC in the form of dimming polynomial curve coefficients. These coefficients are programmable by the customer according to the dimming profile they would like to see. The MLC uses these polynomial coefficients to calculate the PWM duty cycle to 12-bit resolution.

2.2 Boards Features

The ASL5015EVBSLAV board features include:

• Interface connector to attach the ASL5015EVBMST Matrix LED Controller (MLC)
  • ASL5015EVBSLAV can be daisy chained with up to 9 follower boards that hang from a single Leader board
  • Dip switch to select device addresses
  • Populated with ASL5015SHN Matrix LED controller

The leader board is populated with one UJA1163 System Basic Chip (SBC) IC, to enable the communication with the microcontroller or Vector CANoe through CAN (FD) protocol, and to supply the MLC populated in the same board, together with the MLCs populated in the follower boards hanging from the leader board. A maximum of 9 follower boards can hang from a single leader board.

Example of connection between a leader board and a follower board. Up to 9 follower boards can hang from a single Leader board. If there is one or several follower EVBs in the system, create a chain with the leader board using connectors X1 and X3. Also attach customer LED boards to the follower EVBs.

2.4 Accessory Boards

ASL5015EVBSLAV Evaluation Board

The ASL5015EVBMST is compatible with the S32K144EVBQ100. The S32K144EVB-Q100 provides the control signals (through CAN (FD) communication) for the ASL5x15SHN devices. When used with the GUI, the S32K144EVBQ100 drives the channels in the way as selected on the GUI. The S32K144EVB-Q100 can also be used as a system processor to create standalone applications or prototype systems.

Figure 4. UM11224 aaa-030858.

ASL45XASLX41 - Multichannel LED Driver System Evaluation Board

The ASLx500SHN and ASLx41xSHN Evaluation Board (EVB) features the ASL4500SHN, a highly integrated and flexible four-phase DC-to-DC boost converter IC and two ASL3416SHN, a three-channel buck mode LED driver IC delivering constant average DC current. The kit is designed to drive six LED strings with 150 mA to 1.6 A and 2 V to 60 V LED string voltage. In a default application a microprocessor unit (MCU) controls the devices through a serial peripheral interface (SPI).

The ASL5x15EVBMST is only connected to the CAN physical bus of the S32K144EVBQ100 and to the LEDs. The ASL5x15EVBMST EVB is not directly connected to the ASL45XASLX41. More information on the connection of the ASL45XASLX41 EVB can be found in the ASL45XASLX41 User guide (NDA required).

3.1 Hardware Configuration

A full system configuration is completed with the ASL5015EVBMST wired with cable harness for power supply and CAN (FD) communication to the S32K144EVBQ100 associated by the connectors on the ASL45XASLX41 Multichannel LED board. Can also be configured with up to 9 ASL5015EVBSLAV follower boards not shown. Customer can configure using their own LED board.

Figure 7. UM11224

3.2 Configuration Image

To start working with the ASL5x15EVB, the following connections and setup must be performed:

1. Connect the ASL5015EVBMST to the S32K144EVB. Do not forget to supply S32K144EVB-Q100 with 12 V, to enable the CAN communication through the SBC
2. With power turned off, attach S32K144EVB-Q100 12 V DC power supply to ASL5015EVBMST's supply terminals
3. Attach an LED board (example shown in image) to the ASL5015EVBMST. Additionally, if there is one or several follower EVB in the system, create a chain with the leader board using connectors X1 and X3
4. (Optional) If using the optional ASL45XASLX41: attach the S32K144EVBQ100 to ASL45XASLX41, and supply the LED boards with any of the available buck outputs
5. Plug the USB cable from the mini connector end into the S32K144EVB-Q100
6. Plug the USB cable standard connector end into the computer
7. Turn on the power supply. The supply indicator LED (Red LED in ASL5x15EVBMST) (Green LED3 and LED4 in ASL45XASLX41) shall light up
8. (Optional) Use GUI to drive all the evaluation boards (S32K144EVB-Q100, ASL45XASLX41 and all MLC's evaluation boards)
9. (Optional) Use Vector CANoe software to drive MLC's evaluation boards
10. (Optional) Use your own software, microcontroller and LED driver module to evaluate the NXP's Matrix LED Controller using its EVB

4.1 Preparing Graphical User Interface Operating Environment

There are several steps to follow for the full system configuration using the ASL5015EVBMST, ASL5015EVBSLAV, S32K144EVB-Q100, and the ASL45XASLX41 evaluation boards.

3. Copy the flash image (*.srec) file from the one downloaded and unzipped before to the root directory of the S32K144EVB-Q100 USB drive
4. The copy process will take about one minute. Once completed, the S32K144EVBQ100 is flashed and is ready to be used with the GUI, the ASL5x15EVBMST, ASL5x15EVBSLAV and the ASL45XASLX41

4.3 Launching the GUI on Your Computer

The GUI provides easy control of all ASL5x15 EVB and ASL45XASLX41 EVB. To launch the GUI:

Note: The GUI can be found in DocStore, in the following path: LED drivers and controllers / Evaluation boards / ASL45XASLX41 EVB / GUI for ASL45XASLX41 EVB.

1. Locate the GUI folder where you unzipped the GUI
2. Start the GUI by calling the executable (*.exe) file
3. The GUI opens with the startup window

The GUI is divided into several pages. Each page gives some control options to the user. The GUI will always start up with the Setup page.
