GETATKBDRAW
Action
Reads a key from a PC AT keyboard.
Syntax
var = GETATKBDRAW()
Remarks
var The variable that is assigned with the key read fromthe keyboard.
It may be a byte or a string variable.
When no key is pressed a 0 will be returned.
The GETATKBDRAW() function needs 2 input pins and a translation table for the keys. You can read more about this at the CONFIG KEYBOARD compiler directive.
The GetatkbdRAW function will return RAW data from a PS/2 keyboard or Mouse.
While GetatKBD is intended to wait for pressed keys, GetATkbdRAW just returns raw PS/2 data so you can use your own code to process the data.

GETATKBD , CONFIG KEYBOARD
Example
See GETATKBD.BAS
GETDSTIP
Action
Returns the IP address of the peer.
page -506-
© MCS Electronics, 1995-2007
Syntax
Result = GETDSTIP( socket)
Remarks
Result |
A LONG variable that will be assigned with the IP address of the peer or |
|
destination IP address. |
Socket |
The socket number (0-3) |
|
|
When you are in server mode, it might be desirable to detect the IP address of the connecting client.
You can use this for logging, security, etc.
The IP number MSB, is stored in the LS byte of the variable.
See also
CONFIG TCPIP, GETSOCKET , SOCKETCONNECT, SOCKETSTAT , TCPWRITE, TCPWRITESTR, CLOSESOCKET , SOCKETLISTEN , GETDSTPORT
Partial Example
Dim L as Long
L = GetdstIP(i) ' store current IP number of socket i
GETDSTPORT
Action
Returns the port number of the peer.
Syntax
Result = GETDSTPort( socket)
Remarks
Result |
A WORD variable that is assigned with the port number of the peer or |
|
destination port number. |
Socket |
The socket number. |
|
|
When you are in server mode, it might be desirable to detect the port number of the connecting client.
You can use this for logging, security, etc.

Partial Example
Dim P as Word
P = GetdstPORT(i)' store current port number of socket i
GETKBD
Action
Scans a 4x4 matrix keyboard and return the value of the key pressed.
Syntax
var = GETKBD()
Remarks
Var |
The numeric variable that is assigned with the value read |
|
from the keyboard |
|
|
The GETKBD() function can be attached to a port of the uP.
You can define the port with the CONFIG KBD statement.
A schematic for PORTB is shown below
Note that the port pins can be used for other tasks as well. But you might need to set the port direction of those pins after you have used getkbd(). For example the LCD pins are set to output at the start of your program. A call to getkbd() would set the pins to input.
By setting DDR.x register you can set the pins to the proper state again. As an alternative you can use CONFIG PIN or CONFIG PORT.
When no key is pressed 16 will be returned.
When using the 2 additional rows, 24 will be returned when no key is pressed.
On the STK200 this might not work since other hardware is connected too that nterferesi.
You can use the Lookup() function to convert the byte into another value. This because the GetKBD() function does not return the same value as the key pressed. It willdepend on which keyboard you use.

Sometimes it can happen that it looks like a key is pressed while you do not press a key. This is caused by the scanning of the pins which happens at a very high frequency.
It will depend on the used keyboard. You can add series resistors with a value of 470-1K
The routine will wait for 100 mS by default after the code is retrieved. With CONFIG KBD you can set this delay.
