RESPONSES OFTHE EA EDIP160-7VIA SERIAL INTERFACE

The table below contains all response codes. Some response data will come automatically some

others on request. In addition to that with command 'ESC SB ...' user is able to transmit individual data

packages. All reponses are placed into the sendbuffer. With the smallprotocol command ’Request for

content of send buffer’ (see page10) the host can read out the sendbuffer. This can be done per polling,

alternatively pin 20 ’SBUF’ shows with Low-level that data is ready to transmit.

Remarks

automatic responses (placed into sendbuffer)

ESC

A

1

code

Response from the analog touch panel when a key/switch is pressed. code = down or up code of the key/switch. It is

only transmitted if no touch macro with the number code is defined !

ESC

B

2

no

value

When a bargraph is set by touch, the current value of the bar no is transmitted. Transmission of the bar balue must be

activated (see the 'ESC A Q n1' command).

ESC

N

1

code

After a menu item is selcted by touch, the selected menu item code is transmitted. It is only transmitted if no touch

macro is defined with the number code.

ESC

T

0

If automatic opening of a touch menu is disabled (see 'ESC NT n1'), this request is sent to the host computer. The host

can then open the touch menu with the 'ESC N T 2' command.

ESC

P

1

value

After the input port is changed, the new 8-bit value is transmitted. The automatic port scan must be activated. See the

'ESC Y A n1' command. It is only transmitted when there is no corresponding port/bit macro defined !

ESC

H

yHI

The following is transmitted in the case of a free touch area event: type=0 is release; type=1 is touch; type=2 is drag

within the free touch area at the coordinates xx1, yy1

Response only when requested by command (placed into sendbuffer)

ESC

N

1

no

After the 'ESC N S' command, the currently selected menu item is transmitted. noo=0, no menu item is selected

ESC

B

no

value

After the 'ESC B S n1' command, the current value of the bar with the number no is transmitted.

ESC

X

2

code

value

After the 'ESC A X' command, the current status (value=0 or 1) of the touch switch code is transmitted.

ESC

G

2

no

code

After the 'ESC A G nR' command, the code of the active touch switch in the radio group no is sent.

ESC

Y

2

no

value

After the 'ESC Y R' command, the requested input port is transmitted. no=0: value is an 8-bit binary value of all 8 inputs.

no=1..8: value is 0 or 1 depending on the status of the input no

ESC

V

num

version string...

After the 'ESC S V' command, the version of the edip firmware is transmitted as a string

e.g. "EA eDIP160-7 V1.0 Rev.A TP+"

ESC

J

num

projectname string...

After the 'ESC S J' command, the macro-projectname is transmitted. e.g. "init / delivery state"

ESC

DF in KB,

CRC-DF, CRC-DFsoll, DFlen

after the 'ESC S I' command, internal information is sent by eDIP (16-Bit integer values LO-HI Byte)

Version: LO-Byte = version number Software; HI-Byte = Hardware revison letter touch

Touchinfo: LO-Byte = '-|+' X direction detected; HI-Byte = '-|+' Y direction detected

DFlen: number of user bytes in data flash memory (3 Bytes: LO-, MID- HI-Byte)

after the 'ESC UH....' command, a hard copy is sent in BLH Format. xx1,yy1 = Start coordinates of the hard copy (upper

corner)

BLH-Data: 2 Byte: Width, height (in Pixel)+ amount of bytes of image data

amount = ((width+7)/8*height
