Output:

The RS232 is a promising way to communicate with the

Evaluation Board. It is for that we have included the example

codes, with which one can study the RS232 communication.

The example code can be determined from the CD, “\ARM

EVB_LPC2138\Example Codes\Example\UART0&1\”.

To test the RS232 dynamically with the Evaluation Board…

After programming the LPC2138, the user can connect

the RS232 cable from the PC with the COM0/COM1 of the

ARM EVB. The output from the EVB can be displayed in the

PC’s HyperTerminal window as follows:


Start-> All Programs -> Accessories -> Communication ->

HyperTerminal

Choose a name for the window, the COM port number

and select the desired baud rateŦ.

The code can be used to check both UART0 and UART1 of

the ARM LPC2138, by connecting the serial cable with COM0

or COM1 of the EVB.

Ŧ - The default baud rate in our example program is 9600

bits/s.

6.6 Real Time Clock

The Real Time Clock (RTC) is a set of counters for

measuring time when system power is on, and optionally

when it is off. It uses little power in Power-down mode.

On the LPC2131/2/4/6/8, the RTC can be clocked by a


separate 32.768 KHz oscillator, or by a programmable

prescale divider based on the VPB clock. Also, the RTC is

powered by its own power supply pin, VBAT, which can

be connected to a battery or to the same 3.3 V supply

used by the rest of the device.

Features

Measures the passage of time to maintain a calendar and

clock.

Ultra Low Power design to support battery powered

systems.

Provides Seconds, Minutes, Hours, Day of Month, Month,

Year, Day of Week, and Day of Year.

Dedicated 32 kHz oscillator or programmable prescaler

from VPB clock.

Dedicated power supply pin can be connected to a

battery or to the main 3.3 V.


6.7 Serial EEPROM

The AT24C01A/02/04/08/16 provides

1024/2048/4096/8192/16384 bits of serial electrically

erasable and programmable read-only memory (EEPROM)

organized as 128/256/512/1024/2048 words of 8 bits each.

The device is optimized for use in many industrial and

commercial applications where low-power and low-voltage

operation are essential.

Features of AT24Cxx:

Internally Organized 128 x 8 (1K), 256 x 8 (2K), 512 x 8

(4K)

2-wire Serial Interface

segment displays are used. The segment lines of seven

segments LED is being terminated at connector CN5. The digit

select lines are connected to the port pins of LPC2138 by using

BC547. All the common anode displays consume very small

amount of current. User can use segment lines at any port P0,

in all, not (P0.8-P0.15), P1, by default digit select lines

connected to Port P0 of PinP0.10 to P0.13.

the connecter to connect the external circuitry. The relay can

be connected to the Microcontroller through any of the

selected port. But one has to make sure that the Relay and

Buzzer interfaces to GPIO Ports(D7 – D0) is done through the

Upper Nibble (D6, D5, D4) of the FRC connectors JP7, JP8,

JP11, JP12, JP13, JP14.


The Relay and Buzzer are connections in the connector

CN7 are highlighted as above.

The ENC28J60 is a stand-alone Ethernet controller with an

industry standard Serial Peripheral Interface (SPI™). It is

designed to serve as an Ethernet network interface for any

controller equipped with SPI.

The ENC28J60 meets all of the IEEE 802.3 specifications. It

incorporates a number of packet filtering schemes to limit

incoming packets. It also provides an internal DMA module for

fast data throughput and hardware assisted IP checksum

calculations. Communication with the host controller is

implemented via two interrupt pins and the SPI, with data

rates of up to 10 Mb/s. Two dedicated pins are used for LED

link and network activity indication.
