SETFONT

Action

Sets the current font which can be used on some graphical displays.

Syntax

SETFONT font

Remarks

font The name of the font that need to be used with LCDAT statements.

Since SED-based displays do not have their own font generator, you need to define your own fonts. You can create and modify your own fonts with the FontEditor Plugin.

SETFONT will set an internal used data pointer to the location in memory where you font is stored. The name you specify is the same name you use to define the font.

You need to include the used fonts with the $include directive:

$INCLUDE "font8x8.font"

The order of the font files is not important. The location in your source is however important.

The $INCLUDE statement will include binary data and this may not be accessed by the flow of your program.

When your program flow enters into font code, unpredictable results will occur.

So it is best to place the $INCLUDE files at the end of your program behind the END statement.

You need to include the glibSED library with : $LIB "glibsed.lbx"

While original written for the SED1521, fonts are supported on a number of displays now including color displays.

SETTCP

Action

(Re) Configures the TCP/IP W3100A chip.

Syntax

SETTCP MAC , IP , SUBMASK , GATEWAY

Remarks

MAC

The MAC address you want to assign to the W3100A.

The MAC address is a unique number that identifies your chip. You must use a different address for every W3100A chip in your network. Example : 123.00.12.34.56.78

You need to specify 6 bytes that must be separated by dots. The bytes must be specified in decimal notation.

The IP address you want to assign to the W3100A.

The IP address must be unique for every W3100A in your network. When you have a LAN, 192.168.0.10 can be used. 192.168.0.x is used for LAN’s since the address is not an assigned internet address.

SUBMASK	The submask you want to assign to the W3100A.
	The submask is in most cases 255.255.255.0
GATEWAY	This is the gateway address of the W3100A.
	The gateway address you can determine with the IPCONFIG command at
	the command prompt :
	C:\>ipconfig
	Windows 2000 IP Configuration
	Ethernet adapter Local Area Connection 2:
	Connection-specific DNS Suffix . :
	IP Address. . . . . . . . . . . .	: 192.168.0.3
	Subnet Mask . . . . . . . . . .	. : 255.255.255.0
	Default Gateway . . . . . . .	. . : 192.168.0.1
	Use 192.168.0.1 in this case.

The CONFIG TCPIP statement may be used only once.

page -631-

When you want to set the TCP/IP settings dynamicly for instance when the settings are stored in EEPROM, you can not use constants. For this purpose, SETTCP must be used.

SETTCP can take a variable or a constant for each parameter.

When you set the TCP/IP settings dynamicly, you do not need to set themwith CONFIG TCPIP. In the CONFIG TCPIP you can use the NOINIT parameter so that the MAC and IP are not initialized which saves code.

SETTCPREGS

Action

Writes to a W3100A register

Syntax

SETTCPREGS address, var , bytes

Remarks

address	The address of the register W3100A register. This must be the value of the
	MSB. For example in location &H92 and &H93, the timeout is stored. You
	need to specify &H93 then.
var	The variable to write.
bytes	The number of bytes to write.

Most W3100A options are implemented with BASCOM statements or functions. When there is a need to write to the W3100A register you can use the SETTCPREGS commands. It can write multiple bytes. It is important that you specify the highest address. This because the registers must be written starting with the higest address.
