**Chapter 1. Introducing the DAB+ FM Development Board PRO2

**

INTRODUCTION

The following sections provide an overview of the DAB+ FM Development Board and demonstrate how to use it.
The following topics are covered:

• Description of the DAB+ FM Development Board PRO2
• Using the DAB+ FM Development Board PRO2

DESCRIPTION OF THE DAB+ FM DEVELOPMENT BOARD PRO2

• The DAB+ FM Development Board PRO2 provides a platform for developing and evaluating DAB+ and FM receivers. The board contains a Keystone T4B-6D60CDB  DAB/DAB+/FM/EPG/SlideShow the module on a PRO board with a Microchip PIC18F14K40 microcontroller.

The T4B-6D60CDB module is an ultra low power DAB/DAB+/FM receiver module with the following features:

• ETSI EN 300 401 compliant receiver
• DAB/DAB+ sensitivity to -99dBm (typical)
• Decodes multiple audio services up to 256kbps without external RAM
• FM with RDS (RDS reception is subject to certain conditions of power level and frequency deviation)
• Combined antenna input for FM / Band3
• Serial control interface
• RoHS compliant
• EPG
• SlideShow

The Microchip PIC18F14K50 provides a USB to Serial interface for the radio module to communicate with the host PC. Despite the sample code provided in this Development  Board for communicating with the board being based on serial communication, users can analyze the serial communication and implement a driverless HID protocol by rewriting the firmware on the PIC18F14K50.

Chapter 2. Quick Start Guide

 INTRODUCTION

This chapter explained the basic steps to get you started using the DAB+ FM Development Board.

 HIGHLIGHTS

Items discussed in this chapter include:

• Setting up the hardware
• Installing the Microchip’s CDC driver
• Running the sample program

SETTING UP THE HARDWARE

1. Download the DAB+ FM Development Board’s software package from the product website and then unzip the software package to a known folder.
2. Connect the supplied antenna to the SMA connector on the board. The antenna has a magnetic base, sticking the antenna to a large metal surface, for example, a window frame, will produce a better reception. Users need to experiment to find a suitable location to place the antenna.
3. Connect a USB cable (Mini B) to the board and the other side of the cable to the Host PC.
4. Ensure the three LEDs on the board light up.
5. Connect speakers or headphones to the 3.5mm stereo jack, possible to perform this step after the board is ready.

Handling the Board

When handling the board, it is important to observe the following precaution:
Caution Without proper anti-static handling, the board can be damaged. Therefore use antistatic handling precautions when touching the board.
Caution  In order to avoid damaging the board, only operate the board from a USB port’s 5VDC supply.

INSTALLING MICROCHIP’S CDC DRIVER

After the board is being plugged into the host PC, Windows should recognize the board as “CDC RS-232 Emulation Demo”. In the “Welcome to the Found New Hardware  Wizard” window select “No, not this time” and then click “Next >” (Figure 2.1)

The wizard will then prompt the user for a location from which to load the software for the communication port. Select “Install from a list or specific location (Advanced)” and  click “Next >” (Figure 2.2)

The wizard now prompts the user for the location of the .inf file that Windows will use to automatically configure the binary driver files (.sys files) to create the virtual COM  port connection for the USB. Ensure that both “Search for the best driver in these locations” and “Include this location in the search” are both selected. Select “Browse” and navigate to the product software folder unzipped in step 2.3.1. If the user unzip the product software into the root of C driver, the driver files should be in the following folder:

Click “Next >”. The window should now begin loading the driver. If any warnings are issued (Figure 2.4), select “Continue Anyway”.

The wizard should indicate that the software for the Communications port was successfully installed. Select “Finish”. (Figure 2.5)

Next, the virtual COM port will be checked in the Device Manager to identify the COM port number. Click on Window’s Start, Control Panel, System, Hardware, and finally  Device Manager.
Expand the Ports (COM and LPT). The new virtual COM port created by the .inf file should be located in the Ports (COM and LPT) drop-down list in the Device Manager window. Figure 2.6 shows the created COM port. The user’s COM port may differ.

Once the COM port driver has been successfully installed, the TX and RX LEDs will automatically turned off.

 RUNNING THE SAMPLE PROGRAM

The sample program (VB.NET source code included) for the DAB+ FM Development Board requires Microsoft’s .NET Framework 3.5 to work. The .NET Framework 3.5 can be found at:
http://www.microsoft.com/download/en/details.aspx?id=21
After installing the .NET Framework, navigate to the DAB software folder below:
C:\DABSoftware\TestKeyStoneRadio\bin\x86\Release
Execute TestKeyStoneRadio.exe 
Figure 2.6 shows the default start-up screen of the sample program.

Click the green Power On button and select a COM port number created by the Hardware Wizard in step 2.4. The DAB+ FM Development Board will start communicating with the sample software. If everything is working properly, the TX and RX LEDs will start to blink showing communication activities.
The DAB+ FM Development Board is designed and tested in Sydney, Australia. Therefore the stations around the Sydney location get stored in the default memory while the board was under manufacturing test. In order to tune to the user’s DAB/DAB+ stations, double click on the “DAB CHANNEL” word, the sample software will send a full rescan command to the board.
Figure 2.7 shows the basic navigation of the sample software and the function of each button.

1. Station Name. Drag the station name or frequency to Preset Button to save a channel.
2. RDS. Radio text.
3. DAB CHANNEL. Double click to force a full DAB channel to rescan.
4. Total channels of DAB stations stored on the board.
5. Radio status.
6. DAB data rate.
7. Radio reception strength. Click on the tower icon to switch between stereo and mono.
8. Audio volume scale.
9. Radio ensemble name.
10. Preset buttons.
11. DAB stations list. Click station name to play.
12. Mute.
13. Genre.
14. Power on and off buttons.
15. Previous or Next channel.
16. Radio modes select, DAB or FM.
17. Volume control.
18. COM port selection.

INITIAL AUTO SCANNING

When the board is shipped outside of Sydney, Australia, the stored DAB stations will no longer be effective. Users need to perform initial auto scanning in order to receive the local stations of the country. Double click the word “DAB CHANNELS” to perform an auto scan.

PRESET EQ

Users can also select preconfigured EQ like, Bass Boost, Jazz, Live, Vocal, and Acoustic.

ORIGINAL SOUND

If the pure original sound is what you need, then switching EQ off, and sitting headroom to 0 will get you the original sound.

SLIDESHOW

Slideshow adds visual content (slides) to radio broadcasts on DAB or DAB+. It enhanced the digital radio with visuals using images in JPEG or PNG format.

3.2 HARDWARE DESCRIPTIONS

Power Supply Circuit
The board is typically powered by 5VDC from USB. The PIC18F14K50 is drawing power directly from the USB. From the USB’s 5VDC, the power is further distributed into  1.2VDC and 3.3VDC LDO to the KeyStone module. The power of these LDO is always on.

Microchip PIC18F14K50
This microcontroller is used to provide a Virtual Serial Port to the KeyStone module. It is flashed with a customized CDC RS-232 Emulation Demo firmware. Other than performing the standard serial emulation, it also controls the reset and audio shunt of the KeyStone module.

Reset Circuit
Reset of the module is performed by pin emulated by DTR of the virtual serial port.

ICSP
The ICSP programming port is the standard Microchip’s In-Circuit Serial Programming port and is compatible with Microchip’s PICkit.

EXT
EXT port has two 5V logic signals, , and . They are used to control external audio circuitry’s power and mute.

Push Button (SW1)
