• UART-0 uses signal pin from P0.2(TXD0) and
P0.3(RXD0).
• UART-2 uses signal pin from P0.10(TXD2) and
P0.11 (RXD2).
Because Hardware UART of LPC2368 can configure
many points of signal Pin to connect; for example,
UART-2 can use signal Pin P0[10] and P0[11] or signal
Pin P2[8] and P2[9]. Board CP-JR ARM7 LPC2368 selects
signal Pin P0[10] and P0[11] to be the connecting
point with UART-2; so, we must set command to use
signal Pin correctly. Be careful if we use UART
because the Default value of UART-2 is disabled, so
we must enable operation of UART-2 Circuit before
command to Initial values for UART, otherwise we can
not command UART. The example Code to configure
initial values for UART is shown below.
// Config UART-0 Connect to P0[2]:P0[3]
PINSEL0 &= 0xFFFFFF0F;
// Reset P0.2,P0.3 Pin Config
PINSEL0 |= 0x00000010;
// Select P0.2 = TxD(UART-0)
PINSEL0 |= 0x00000040;
// Select P0.3 = RxD(UART-0)
// Config UART-2 Connect to P0[10]:P0[11]
PINSEL0 &= 0xFF0FFFFF;
// Reset P0.10,P0.11 Pin Config
PINSEL0 |= 0x00100000;
// Select P0.10 = TxD(UART-2)

Application of RS422/485
For RS422/485 Communication Circuit of Board CPJR ARM7 LPC2368 uses UART-3 and then use signal Pin
P0[0] and P0[1] to be the connecting point. We can
use this circuit to configure operation of Line
Driver Circuit to be either RS422 (Full Duplex) or
RS485 (Half-Duplex). If it is RS422, it can transmit
and receive data simultaneously as bidirectional as
RS232 but this function is longer distance. On the
other hand, if it is RS485, we can configure its
format of communication to be either Half-Duplex or
Full Duplex; in this case, if it is RS485 (FullDuplex), it is similar to RS422 but we must control
ON/OFF circuit of the transmitter; on the other hand,
if it is RS485 (Half-Duplex), it will alternate
function between receiver and transmitter by using
signal P1[19] to be Output Port function for setting
the direction of data. If status of P1[19] is Logic
“1”, it configures the direction of data to be
transmitter but if status of P1[19] is Logic “0”, it
configures the direction of data to be receiver. The
IC Line Driver of circuit can select either No.75176
or MAX3088; if using 75176, the maximum point that
can be connected signal of RS485 as Multi-Drop type
is 32 points; but if using MAX3088, the maximum point
that can be connected as Multi-Drop type is 256
points. The connector of RS422/485 is CPA-6 Connector
that has arranged as shown below.

Figure displays circuit of RS422/485.
If we want to use it to be RS422, we must
install 2 IC Line Driver Circuits and set Jumper J19
and J20 to be RS422 (Full Duplex) as follow; set
Jumper J19 (FULL/HALF) on FULL side and then set
Jumper J20 (422/485) on 422 side.
If using RS485 (Full Duplex), we must install 2
IC Line Driver as same as RS422; but in this case, we
must set Jumper J19 and J20 to be RS485 (Full Duplex)
as follows; set Jumper J19 (FULL/HALF) on FULL side
and then set Jumper J20 (422/485) on 485 side. The

operation is similar to RS422 because it can
simultaneously
transmit
and
receive
data
as
bidirectional type like RS422 but it can be connected
as Multi-Drop type. The circuit can receive data all
the time through IC Line Driver of U6 and IC Line
Driver U7 will transmit data. In this case, it can
control ON/OFF operation of transmitting data by
signal from P1[19]; if status of P1[19] is Logic “1”,
it enables operation of transmitting data but if
status of P1[19] is Logic “0”, it disables operation
of
transmitting
data.
When
the
operation
of
transmitting data is disabled, its status is similar
to removing cable of the transmitter from circuit, so
signal on the transmitter does not crash data of
other devices. We must write program to control all
devices to transmit only one data into a line once.
If using RS485 (Half-Duplex), we must install
only one IC Line Driver at position U7; in this case,
we must set Jumper J19 and J20 to be RS485 (Half
Duplex) as follows; set Jumper J19 (FULL/HALF) on
HALF side and then set Jumper J20 (422/485) on 485
side. Moreover, we must interface cable of CPA-6(J18)
Connector at the position TX(-) and TX(+); in this
case, function of TX(-) is RS485(-) and function of
TX(+) is RS485(+). Direction and function of this
signal RS485 depends on status Logic of P1[19] that
is Pin Output Port and its function is Direction
Control.
The method to set Jumper of Fail-Save Resistor
and Terminate Resistor is describes as follows; if
Board is generally installed in the beginning
position and destination of these Jumper Cables, we
must enable and then set Jumper(EN/DIS) of RZ, RL,
RH, TZ, TL and TH on EN side or always Enable. The
Fail-Safe Resistor (RL, RH, TL and TH) makes status
Logic in the signal cable is in the correct IDLE
status while not receiving and transmitting any data.
For the Terminate Resistor (RZ and TZ) will
compensate the resistance or Impedance that is
occurred in the line if it is very long line.
Code for writing program to configure operation
of UART-3 of RS422/485, we must use P0[0] and P0[1]

User’s Manual of Board Microcontroller CP-JR ARM7 LPC2368
to be the connecting Pin and then use P1[19] to
control the direction of receiving and transmitting
data of RS485. Be careful, the Default value of the
UART-3 Circuit in LPC2368 is normally disabled; so,
if we want to enable operation of this circuit, we
must not forget to write command to enable operation
of UART-3 before setting configurations into circuit.
The method to enable operation of UART-3 is to be
controlled by Bit in Register PCONP as example below.
// Config UART-3(RS422/485) Connect to P0[0]:P0[1]
PINSEL0 &= 0xFFFFFFF0;
// Reset P0.0,P0.1 Pin Config
PINSEL0 |= 0x00000002;
// Select P0.0 = TxD(UART3)
PINSEL0 |= 0x00000008;
// Select P0.1 = RxD(UART3)
PCONP
|= 0x02000000;
// UART3 Power-ON
// Config P1.19 = Output Control Direction RS485
// P1.19 = "0" = Received RS485
// P1.19 = "1" = Transmit RS485
PINSEL3 &= 0xFFFF3FFF;
// P1.19 = GPIO
IODIR1
= 0x00080000;
// Pin Control Direction RS485 = Output
// Select Direction RS485 = Receive
IOCLR1
= 0x00080000;
// RS485 Direction = 0 (Receive)
// Select Direction RS485 = Transmit
IOSET1
= 0x00080000;
// RS485 Direction = 1 (Transmit)
Port I/O Connectors of Board
For Port I/O Connector of CPU is arranged
outwards, so it makes user be able to connect as
desired; in this case, there are 6 sets as follows;
• 2 Sets of IDE 10 Pin Connector; each set has 8
Bit
that
is
P2[0..7]
and
KEY4X4
(P0[4..7],P1[20..23]). Its signal arrangement is
shown below.
