2.2 Power Supply of Embest S3CEV40

Embest S3CEV40 development board uses nominal current of

500mA/5VDC. The board is assembled with a special-purpose DC adapater, so

that power can be supplied to the board via the adapater or an external.

2.3 JTAG Connection

Figure 2-3 is the model of Embest S3CEV40 development board. The host

is connected to the development board via JTAG emulator. The operating and

developing environment of the host, e.g. Embest IDE, can be directly

downloaded with the emulator and then debugged.

Figure 2-3 Development Model of Embest S3CEV40

Embest S3CEV40 development board provides a standard 20-pin JTAG

interface. User can use the JTAG line attached to this board to connect the

emulator.

2.4 Serial Port Connection

User can use the serial port line enclosed with the Embest S3CEV40

development board to connect the development board and the host. The host

communicates with the development board through the HyperTerminal (PC),

so as to facilitate preliminary hardware testing.

The serial port line connects port UART0 of the development board. The

HyperTerminal setting for host operating is serial port COM1 or COM2 and the

baud rate is 115200, as shown in Figure 2-4:

Figure 2-4 HyperTerminal Serial Port Setting

When correctly connected, the HyperTerminal will will be shown as in

Figure 2-5.

2.5 Hardware Testing

A detailed hardware test program is provided by Embest Info & Tech Co.,

Ltd. Open the disk attached to the board, copy S3CEV40 routine file to

EmbestIDE Installation Directory\Samsung folder, run corrpesponding files in

the workspace and you can test any individual hardware of the board.

User can also use the testing program provided by Embest Info & Tech Co.,

Ltd to test the hardware of this board in following steps:

1. Use the S232 standard serial port line to connect the development board

and the host,

2. Turn on the power,

3. All the 8-segment Digit LEDs of the development board are on. LED1 and

LED2 flashes in turn,

4. LCD screen displays the information showed as Figure 2-21. The

HyperTerminal output is shown in Figure 2-5:

Ethernet DHCP test, user must run the DHCP Server program or other similar

dynamic configuration tool on a local or networked PC. The DHCP Server

software used by this example is shared, so it is not available in the disk. User

may use any other similar tool software. Enter “ 6 ” into the PC HyperTerminal

after DHCP is conFigure d and parameter is set. If no dynamic IP configuration

software is running, or if the dynamic IP configuration software is running

abnormally, the HyperTerminal output will be as shown in Figure 2–12. Press

“ ESC ” and return to the initial state.

0 TouchScreen Test: When this test is activated, the HyperTerminal

output will be as shown in Figure 2-19. The touch screen is divided into 16

panes and displays 0~F. When touched, the LCD touch screen outputs a

corresponding coordinate value at the HyperTerminal through the serial port,

and, (at the same time, outputs the previous touch coordinate, whose origin is

near the top left of a 4x4 keyboard) as shown in Figure 2-20. The touch

screen, theoretically, can identify 1 unit. An identification interval of 10 units is

suggested for touch-screen design. The ex-work test program only finished the

digital-analog conversion test on the touch screen. As to the coordinate

location, please refer to TouchScreen_Test routine. Press any key on the PC

keyboard to return to the initial state.
