2.3 Quick Start:

The SBC2104 (Single Board Computer 2104) starter kit is shipped with an ARM LPC 2104 micro controller.The default jumper settings will allow the micro controller to exe-cute from the clock source and voltageregulator on the SBC2104 board. The micro controller is programmed with a test program that toggles theLEDs.

Use the supplied 10-pin cables to connect the header marked HD1 with the header marked HD8. Anexternal 10 - 15V DC power supply is required. The input circuit is a full bridge rectifier. Connect the power

cable between a power supply and the SBC2104. Apply 10 - 15V DC to the power connector. The powerswitch turns the SBC2104 main power on and off. The red LED is lit when power is on. The program runningin the LPC 2104 now flashes the LEDS.

RS232 COM PORT

The SBC2104 should be connected to the COM port of your PC as shown in the figure 2-2. NowInstall the LPC 2000 FLASH UTILITY from the CD supplied with this kit in the folder Software Tools. To

program the Target ARM LPC 2104, power off the SBC2104 kit. The jumper JP2 should be installed on theboard. This enables the inbuilt BOOT LOADER code that is present on the chip. This code is set up in theROM during the factory settings. Now power ON the Kit and send the hex file of your application throughPhilips LPC2000 Flash Utility.

2.3.2 Programming the Target Device:

The SBC 2104 is controlled from PHILIPS Flash Utility, version 2.1.0 and higher. Philips Utility is anintegrated development environment (IDE) for downloading the ARM Application executables (.hex(INTEL)).

To program a hex file into the target ARM device, Select he Flash Utility from the Start Menu Of Your OS.Select the target Device LPC 2104 from the Pull Down Menu. Enter the XTAL Freq to 14745 kHz. Select theCOM port from the Communication Frame to which your Board is connected. Select the Baud rate. SelectionOf Higher Baud Rate transfers the code in a less time to the Target. Now Press the Read Device ID Button. Itwill prompt to reset the Board. Now press the Reset Button on your Board and Press Ok in the Utility. If theBoard is detected, you can see the Boot ID and the Part ID are filled up else the Utility presents an Errormessage on the Screen that Cannot communicate with the Test Board. Locate the Hex file and downloadthe HEX file into the target using the Upload to Flash Button. For Verification of the data download, pressthe compare Flash Button. In both the cases, the progress bar shows the Progress of the job. To run theapplication, uninstall the jumper JP2 after Power Off and Turn On the Kit.

If you still see any errors with the communications of the board, see the Trouble shooting section.

3.1 Description Of USER LEDS

The SBC 2104 includes 8 Green User LEDS and 3 Push Button Switches. The LEDS are connected tothe debug headers, which are separated from the rest of the Board. They can be connected to the ARM devicewith the supplied 10-wire cable to the pin header of the ARM I/O ports. The ARM processor IO PORTS arealso extended to the External Headers. The LEDS can be connected to any one of the Headers (HD1, HD2,HD3, HD4). The LEDS were connected to the Header 8 (HD8). The cables should be connected directly fromthe port header to the LED. The cable should not be twisted. A red wire on the cable indicates pin 1. Confirmthat th is is connected to pin 1 on each of the headers.Figure 3-2 shows how the LEDS should be connected

to the User IO ports.

Figure 3-2 Connection Of User LEDS:

Figure 3-3 Implementation Of LEDS and LED headers:

Note: The ARM can source or sink Current directly. The above figure descriptions of the user LEDS and how they are connected tothe Header 8.

3.2 Description Of the User Switches:

The switches connected to the debug headers are implemented as shown in the figure 3.4

Figure 3-4 Configuration Of switches for External Interrupts

Figure 3-5 Installed Jumpers For Configuring Switches

The External Hardware Interrupts can be used in two ways.

1. By the Use of switches.

2. Can be connected to External Hardware using HD9.


12/19


SBC 2104

12 18 October 2004

Using Switches:

The jumpers JP5, JP4, Jp6 need to be installed for Operation Of External Hardware Interrupts using Switchesas shown in the figure 3.5.

For the External Interrupt INT0-JP4 need to be installed to the pins 1&2. SW2 switch is configuredfor INT0 here.



When the corresponding switch is pressed, a low signal triggers the corresponding Interrupt.

The HD9 header can be used if the user wants some interrupt from the outside world of the kit.

3.3 IO Ports

The pin out for the IO Port headers is explained in the figure 3.6.

Figure 3-6 Pin out for the IO Port Headers

HD1 is connected to P0-7 of the LPC 2104.




The Pin1 of all the Headers were connected to 5 V DC and the Pin 10 were connected to GND.

3.4 Description of the RS-232 Interface

The SBC 2104 includes 2 Serial Ports. One RS-232 Port is used for communication with the PC whileProgramming the Target. Once the Target is programmed, the user can very well use this RS 232 port forUser Communication with the PC. The Other serial Port is used for communication with the externalMODEM. This was an excellent feature and it can be used in many Industrial and commercial applications.

Note: There is no need to instal l any jumper for the usage of the Ser ial Por ts. See the schematics suppl ied

with this document for brief overview of Which Port i s used for normal RS-232 communication and which

is used for Ful l modem communication.

3.5 Description Of PWM, I2C and SPI headers

Figure 3-7 PWM, I2C and SPI headers

PWM Connection To the User LEDS:

Figure 3-8 PWM signals connection to the User LEDS:

Here you can use a 10-pin cable for the connection of the available PWM channels to the User LEDS. Make


14/19


SBC 2104

14 18 October 2004

sure that you didnt connect the PWM channels to the VCC of the USER LEDS. While connecting to thePWM channels, leave the first two pins of the cable 1 & 2 and the last two pins of the cable 9 & 10 so thatcable header exactly comes in the middle.

SPI interface connections:

The available connections in the pin header are P4, 5, 6, and 7. The alternate functions of these GPIO pins areSCK, MISO, MOSI and SSEL. You need to have an additional external Hardware for the usage of these Pins.For example you can connect these four pins to a Data Flash, which is also featured with SPI protocol.

I 2C Connections:

The available connections in the pin header are P2 and P3. The alternate functions of these GPIO pins areSCL and SDA. You need to have an additional external Hardware for the usage of these Pins. For exampleyou can connect these two pins to an external RTC, which is also featured with I2C protocol.

3.6 Description of ON BOARD JTAG circuit:

The WIGGLER circuit used on this board is used to communicate the Target Board with the PC using a

TCP/IP port. The On-Board circuit reduced the need of an external Interface that is to be connected to theJTAG header. The GNU-GDB supports these utilities and can directly load, run, set Break points as issued bythe User. For a detailed description of using the Debugger, Read the INSTALLATION PROCEDUREDOCUMENT AND HOW TO USE GCC MANUALS.

No Jumper Settings need to be installed while using the JTAG. Remember the pins TMS, TCK, TDI, TDO,TRST, DBSEL and rTCK will not function as GPIO pins. While using the JTAG circuitry, the Header HD2is proposed to leave unconnected.

The brief explanation of using JTAG circuitry is explained in the INSTALLATION PROCEDUREDOCUMENT AND HOW TO USE GCC MANUALS provided with the CD. The parallel Port DB-25 pinconnector on the kit should be connected to the PC parallel port using a D-25 pin Parallel port cable. The

schematics of the JTAG WIGGLER circuit were shown in the schematics.pdf supplied with the CD.

3.8.2 Main Power LED

The red power LED is directly connected to the SBC2104 main power supply. The power LED is always litwhen power is applied to SBC 2104.

3.8.3 Main Power Switch

The Sliding switch allows the user to Power OFF/ON the Main Power Supply.

3.8.4 ON-BOARD Regulators for the Target

Three On-Board regulators were used to supply 3 different voltages 5V, 3.3V and 1.8V to the TargetProcessor. The Test Pads TP1, TP2 and TP3 can be used to test these different voltage levels. As most of theStandard TTL logic devices support 5V, all pin headers on the board are added with a 5V Pin so that the usercan interface any external circuitry easily.
